It is not possible to set some fields as mandatory using fieldcatalog or by layout setting. But we can write some logic to check the whether required fields are filled or not and then give an error message.

Before updating the values, check the internal table whether all the required fields have been filled or not, other wise give an error.

LOOP AT lt_output INTO lwa_output.

IF lwa_output-req_field IS INITIAL.

MESSAGE e000(z1). "Field is mandatory

ENDIF.

ENDLOOP.

Regards

Hi,

Which ever field you want as mandatory,in the fieldcatalog place the component VALEXI as 'X'. It would make that field mandatory.

Hi Dishant,

thats not right, sorry...valexi works only, if in the dictionary is a foreignkey or valuetable defined...
