UPPER() Key Columns

[Sirfyaad]

Hi Team,

I have created a table inside which the column is Client Id. And I have also created an action behavior for the same column but I am facing an error. Appsheet is not running UPPER() functions for key columns. how can I run this action behaviour.

You can't because you are not able to modify key column's value after it's created.

Any suggestions

If the goal is to have that key column with upper letters, use a validation and your own error message. For that purpose this should do the job..
FIND([KeyColumn],UPPER([KeyColumn]))>0
