Blank values are saved as the Initial Values column for these fields is set.

Check table definition in SE11 or SE12.

3rd column is for Initial values. Remove the checks. Blank values will not be allowed.

when i check the key field column it automatically checks the initial value column for those fields on activation

The SM30 screen of the table ZMM_ZPRMSEL must be created in a Z function group.

Add your validations in the module pool program of the screen.

You can change the Z function group the way you want.
