Field Exits

I have a requirement to put validation to the fields of transaction F-28. My requirement is :

I have to put validation like this.

I have 2 fields Reason code field and Xref2 field.

I have to check reason code field, if it is not empty then xref2 field should not be blank. I dont have parameter id's also for these fields.

So how to do validation using field exit.

Thanks & Regards

Haritha.

hi Haritha,

you can do this with validation (transaction GGB0). Let me know if you need more help!

Try to create field exits for both.

Field exit for the reason code would be like this:

if input is not initial.
  l_reason = input.
  export L_reason to memory id 'ZF28'.
endif.
output = input.

In the field exit of the XREF2, check the value of the L_REASON from the memory.

IMPORT L_REASON TO MEMORY ID 'ZF28'.
IF NOT L_REASON IS INITIAL.
* ... CHECK THE VALUE OF THE XREF2
ENDIF.
FREE MEMORY ID 'ZF28'.

Both L_REASON should have a same data definition.

I haven't tried this one.. but you can try it.

Hi,

You can use FM DYNP_VALUES_READ to read value of Reason code and Xref2 field values.

You have to pass program name , screen number and field name to the above FM.
