🔍 This page covers the initial connection and configuration of the the Luware Power BI Template, allowing you to retrieve Nimbus call data (via OData interface) from your data cluster. If you already connected your template before and want to learn more about the individual parts of the template itself, head to the Power BI Template Usage section
REPORTING CHECKLIST
✅ Nimbus Reporting - Roles and Licensing
-
Out of box, only users with specific (Service Admin, Supervisors Admin User Roles) have access to the BI OData Interface.
- General Reporting queries work with any Tenant / Service admin role.
-
Contact Center Optional Nimbus Features:
- Extended User States reporting, require an additional Contact Center license in order to apply the User Role → “User Supervisor” to your service account.
- Access to BI User / Service Session data can also be granted to Contact Center licensed users. A specific User Role → “Service Supervisor” enables access to the Odata interface, while also granting Supervision features in the Nimbus Frontend.
☝ Important Licensing Notes
Each additional user to access Reporting data can result in additional costs, as the required Contact Center licences are subject to a charge. Get in touch with Customer Success to discuss your needs on roles and licensing.
Without the according user role, the tabs User States and Service / User Session data on the Nimbus Power BI Report Template may remain blank, or not update anymore after a data query.
✅ Please ensure to hold the according Admin / Supervisor O365 user credentials ready when connecting via Power BI desktop. The detailed connection steps are explained below
✅Power BI and PC Requirements:
Nimbus uses Power BI to connect to your tenant via OData Feed and retrieve the necessary KPI facts and dimensions according to the Nimbus Reporting Model. Since the BI Report File is stored locally on your PC, no Power BI Pro account is needed to use this feature.
- The Power BI Desktop App, Version 2.87.xor better is required to use all Nimbus features. We always recommend keeping your Power BI Desktop version up to date.
- Note that querying, displaying large call session volumes in BI Desktop requires substantial amounts of RAM and hard drive space, leading to errors if either is insufficient on your PC. Even on high-speed internet connections a query with millions of entries can take several minutes. Refer to our “Known Issues and Solutions” section below when you encounter issues.
- We recommend to always use our latest BI template files, downloaded to the PC in which you inspect Nimbus retrieved data.
INC Nimbus Power BI Files
✅Luware provides the following Power BI Files. Contact Luware Support or your Customer Success Specialist to get the latest version.

Configure Connection
- Open Power BI Desktop.
- Open the Nimbus report file (Nimbus.pbit).
💡 You may immediately abort any update process as it will fail without proper connection details. When opening the Template for the first time you will be requested to parameters → See next step. - As the report connects you will be requested to enter the connection details and other parameters.
- Determine the URL below, depending on your Tenant data cluster location, as specified during Nimbus Installation.
In most cases this region is selected by your tenant administrator when provisioning the first Nimbus service.
🤔 I'm not an admin. How can I find out my data cluster location?
When you log into https://portal.luware.cloud, keep track of the URL shown in your browser. Depending on the Cluster you are on the URL will change: - Example: The UK data cluster uses a "UK" subdomain while Germany uses a "DE" prefix.
- If the base subdomain does not change as you remain in Switzerland.
- Depending on your cluster, copy the URL from the list below:

☝ Note that the "DaysLimit" and "From/To Date" directly affects how much data is being downloaded when you refresh the report. This value has a great impact on Power BI's processing.
🤔 Not seeing this dialog? It might have been closed on accident. Please re-open the report file, as this dialog opens as default when the parameters are missing.
💡 After the connection dialog was confirmed, values can be changed again later. → See "Customize Template Parameters" chapter below.
Provide your Connection Details
✅ Your Nimbus team owner credentials must be held ready for this. Nimbus uses impersonation permissions to connect to the data source.
- On the OData Feed Login Window, switch to the tab: "Organizational Account"
- Sign in by providing your team owner O365 credentials (the same you would use within Nimbus) → 💡 You will be asked for permissions to impersonate your user to access Nimbus data on your Tenant.
Learn more...
✅ Connecting to your reporting data via the Nimbus API will request delegated user impersonation permissions from a user with tenant administrator privileges. The permission will be requested by either the Power BI Desktop application or by Power BI Online when trying to access your Tenant data for the first time

Click on "Connect" and allow for up to 1 minute to establish a connection.
Note: Depending on your parameter and call volume on your Nimbus Tenant the data retrieval process can take >10 min, as Power BI also needs to build the Reporting Model around your data. → As long as no error is shown you can leave the "Refresh" running, even if it appears stagnant for a while.
- Once the refresh is done, inspect the BI Report
→ your O365 Tenant Nimbus Session Data should now be loaded into the template.
At this point you can go and learn about the Power BI Template Usage or carry on with the steps below to adjust further parameters.
☝ Please note that nearly each parameter change requires a data query refresh within the entire template.
Customize Template Parameters
ABOUT PARAMETERS
- Certain parameters in the BI Template can be adjusted to your liking. To do so, make sure the BI Template is opened, then go to Home Ribbon > Transform Data > Edit Parameters.
- On paramter changes we recommend to update via " Apply changes" (Yellow bar) instead of pressing the "Refresh" button from the ribbon bar. This saves time as "Apply changes" only queries the actually needed data instead of the whole set.
| Parameter | Notes | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Connection URL | Connects your template to the data repository. This parameter usually doesn't need changing once you've configured it for your Template at first startup. However if you're having problems connecting – or need to connect to a different source – you can check and adjust the parameter at any time. → Also refer to the "Configure Connection" step above. Here are the connector links again for reference: INC Nimbus OData Connector URLs
✅ Make sure to configure your web proxies to allow access to these domains or whitelist the complete *.luware.cloud domain. 💡 If you need to connect to multiple tenants and their data, we recommend saving multiple reports, each with their individual connection parameters. 🤔 Connection Problems? → Read our “Known Issues and Solutions” section below. |
||||||||||
| Last X Days (Lookback) |
Changes the number of days, always referring back from the current date (today). Useful when you want to your report consistently look back at a certain amount of days. 💡 When defined, this value takes precedence over "From Date and To Date" parameters. Leave it blank when you want to define a specific time range. |
||||||||||
| From Date and To Date (Range) |
Allows to specific a specific date range for the query. This is useful when you have a very large monthly call volume that would slow down the report query significantly, or in case you want to ignore certain periods of data. 💡 The date must be specified in a yyyy-MM-dd format. Otherwise the parameter will be ignored. |
||||||||||
| Generate Unified Sessions |
Unified Sessions consolidate Caller (Customer) data like PSTN or Name, the Caller Path (Transfers, Customer Journey, Services Called) and indivdual call Session Times with a Final Session Outcome as a new lookup table. 🔍 This option loads and processes data for the "Unified Sessions" Tab for drilldown purposes. Also see Power BI Template Usage > "Unified Sessions" tab. ☝ Enabling this parameter (EnableUnifiedSessionLoad = TRUE) can have a significant impact on your data queries. If you do not need session outcomes in your report, consider disabling this. On errors during your query refer to our “Known Issues and Solutions” section below. |
||||||||||
| Load User States |
🔍 This option loads and processes data for the "User States" Tab for drilldown purposes. Also see Power BI Template Usage > "User States" tab. ✅ In order to generate data this feature needs to be enabled. → See Tenant Administration > "Data Privacy" > "Show User Time in State". ☝ Enabling this parameter (Enable UserStatesLoad = TRUE) can have an impact on your data queries. Learn more about User States to determine if this option is needed for your reporting needs, as it also conserns personal data (GDPR) protection laws. On errors during your query refer to our “Known Issues and Solutions” section below. |

Known Issues and Solutions
Connection Problems
🤔 Connection Problems: If your connection to the Odata source fails outright, there are a few steps you can follow.
✅ Try these steps:
- Ensure that your connecting user fulfills the role criteria described in the prerequirements. Also see Portal Roles > Reporting / Odata
- If for any reason the connection window does not appear or errors occur, go to File > Options and Settings > Data Source Settings and revoke any user permissions / login data specified in your Nimbus reports.
⮑ The next time you open the Nimbus BI report or trigger a data refresh you should be asked for new credentials again.
⮑ In case of a wrong OData URL you can also change the template parameters. - Also ensure that the "ConnectionLink" parameter in your template was set to the correct Nimbus cluster. Your user credentials will not work on a different data cluster URL. To identify your cluster, log into the Nimbus Admin UI and check the URL redirect in your browser.

Data Privacy Firewall causing query errors
🤔 High volume query errors: Particularly on high data volume queries, we currently get issues reported that relate to the BI Data Privacy firewall. We continue to investigate this case to make further improvements to our query and templates as needed.
Learn more…
✅ Current workaround → If you encounter problems with your version of Power BI, please follow these steps.
💡 Do not load the template file or data yet. Close any report files, but leave Power BI open.
Head to Power BI Options and Settings > Options > Global > Privacy
- Ensure "Always ignore Privacy Level settings" is selected
Next, head to Power BI Options and Settings > Options > Global > Security
- Select "Allow any extention to load without validation or warning"
Finally, open your Nimbus Report file and provide the connection details, starting with a small time-range test query.
💡 If everything works as required, continue to expand your query sizes. However, consider the known BI Performance Issues warning below in mind.
💡 If there still are issues: Head to Power BI Options and Settings > Options > Global > Security
Verify that "Ignore the Privacy Levels and potentially improve performance" is selected. If it is not, check the previous steps first, then and follow the linked Microsoft documentation for more details.
Unable to read transport connection (on WiFi)
🤔 When trying to connect “OData" the following error is shown:
Unable to read data from the transport connection. A existing connection was forcibly closed by the remote host”.
This error can occur due to the Wifi network protocol being set to IPv6.
✅ Try these steps:
Microsoft advises that changing the network protocol as follows, solves the issue:
- Go to Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings
- Double Click Wifi
- In General Tab, click properties
- Uncheck Internet Protocol Version 6 (TCP/IPv6)
- Click “OK”
Query aborted with unspecific errors
🤔 Query abort issues or errors?
Sometimes BI is not building the tables properly or conflicted with data from a previous query. Try another data refresh, as it can sometimes resolve the issue.
✅Try the following:
- Ensure to save, close and re-open your template prior to a refresh to ensure no other queries are hanging.
- Depending on your session data amount, queries can take up several minutes. If timeout-errors are returned from the OData API, try decreasing your date range and/or remove taxing session / user state parameters to improve loading speed.
- Power BI Desktop can struggle as report files reach several gigabytes in size. Ensure your PC has sufficient hard drive space and RAM to manage large amounts of data.
Performance issues and long query times (>10 minutes)
🤔 Performance Issues: On recent BI Versions – running on Windows 11 in particular – we have noticed considerable CPU and RAM usage spikes both during BI queries. The high frequency data access can lead to query errors (e.g. out of memory, connection forcibly closed) as your computer hits CPU and RAM boundaries.
Learn more…
💡 The Report parameters Unified Sessions and User States greatly increase the data load on Power BI and thus can increase the occurrence of query errors and connection aborts.
- Even on a powerful PC with good internet connection you must still expect overall query and calculation times of ~10-15 minutes. → We recommend using a workstation equipped with Core i7 CPU or newer and at least 16 GB RAM to keep processing speeds acceptable.
- Our BI template has been tested with up to 2 million call sessions. → With additional data parameters (Unified Sessions, User States) enabled we recommend querying your date range in smaller ranges and increments. This is especially applicable when you are running services with high call volumes >1 million monthly sessions.
✅ Recommended workarounds
→ If you got a Nimbus .pbit template file successfully connected and used for queries, save it as a .pbix report file for continued work. We have noticed considerably lower resource usage on pbix file extensions.
→ Consider decreasing your reporting range and/or deactivate unneeded parameters to strike a balance between query times and data reported.
Invalid Resource Error
🤔 “Invalid Resource” Error: New tenants setting up Power BI template connecting to the Nimbus historic data via the OData URL no longer get the message to grant permission but are faced with the error:
access_denied: AADSTS650057 : Invalid resource.
Learn more…
🔎 This is a problem with MS app permission management issue, not specific to Power BI. We suspect that this issue is due to some recent changes made by Microsoft in its app permission management system.
✅Workaround:
Create the application as a Global Admin for the 'Microsoft Power Query for Excel' default app (Power BI Desktop).
Connect-MgGraph -Scopes 'Application.ReadWrite.All'
New-MgServicePrincipal -AppId 'a672d62c-fc7b-4e81-a576-e60dc46e951d'Copy and execute the following API consent link as a Global Tenant Admin:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=a672d62c-fc7b-4e81-a576-e60dc46e951d&response_type=code&response_mode=query&state=12345&prompt=consent&scope=https://[cluster_uri]/user_impersonation☝IMPORTANT: Replace [cluster_uri] with the API URL relevant to your cluster. You can find your cluster by logging into the Nimbus Admin UI, then check the browser address bar for the redirected URL that indicates your cluster location. Below is a list of all our cluster URLs:

STILL NOT WORKING AS INTENDED?
🤔 Still having Issues?
- When encountering frequent errors, ensure you test-run the latest “clean” template provided by your Luware Support or Customer Success. This helps to narrow down and exclude any errors caused by leftover data structures, old queries, deprecated features or “hidden”manual changes.
- Especially after major reporting feature or parameter changes (see Nimbus BI Template Release Notes) we recommend starting on a fresh template (Nimbus.pbit / .pbix).
- If your problem still persists on a new template, don't hesitate to contact us to analyze the issue.
