Consult the Power Apps Community for Targeted Guidance
Since this involves specific Microsoft Power Apps customization, the best approach is to gather your form configuration details and seek targeted guidance from specialists in the official community.

Note down the exact table names and column types for both the Project ID and Analytical ID fields within your Power Apps environment.
Check your current form setup and any existing business rules to ensure that a new automation rule will not conflict with current processes.
