Issue with Dynamic text in Textbox

Thankyou, Greg_Deckler, for your response.

Hi samratpbi,

We appreciate your inquiry on the Microsoft Fabric Community Forum.

Based on my understanding, the dynamic value feature in text boxes depends on the Q&A natural language engine in Power BI. In large models with many tables or measures, the Q&A index may fail to detect certain measures or may ignore filter conditions due to ambiguity, cache issues, or poor Q&A configuration.

Please follow the steps below, which may help to resolve the issue:

1. Update to the latest Power BI Desktop, as new releases often include fixes for Q&A and text box integration.
2. Re-initialise Q&A by adding a temporary Q&A visual and completing the Q&A setup. This refreshes the natural language index used by text boxes.
3. Clear local caches by navigating to File > Options and settings > Options > Global > Data Load → Clear cache, then restart Power BI. This often resolves measure not found issues.
4. For large models, use Q&A setup to exclude unnecessary fields and consolidate your measures in a dedicated Measures table.

If you require inline formatting such as bold numbers within sentences, a possible workaround is to insert multiple Value placeholders in the text box and format each one individually. Alternatively, you may concatenate values into a single DAX measure if consistent formatting is acceptable.
