I have a custom table in BC, and I need to add another field into the primary key. However it will not publish if I try that.
This table has no data in it so no issue with losing any data.  I have tried the below method however it seems to have no effect.

    Hi,
     
    Are you using docker or something similar to test the code where it will not publish?
     
    If so you can change the launch.jason file to recreate instead of synchronize:
     
    "schemaUpdateMode": "Recreate"

    In the launch.json file, set the Schema Update Mode to "Recreate"..
     
     
    Since you mentioned that there is no data in the table, it will automatically delete your existing data. You can proceed either directly publishing the project or by building the project (pressing Ctrl+Shift+B) and then manually uploading the .app file

    Hi, just to add one more point, if it is a production environment, please refer to the documentation below.
    Business Central 2021 wave 2 (BC19) new features: Force sync of customer-specific extensions in online environments (ForceSync mode in Production Environment)
    In-depth testing for Force Sync mode in Production Environment (Renaming tables, Renaming fields, Changing field type…)

    Hope this helps as well.
    Thanks.
