User Exit for ME21N First screen

Hi,

I found out the so many enhancements for the Transaction code Me21n. But Whicg enhancement is used for writing the code for the First screen. That means by entering the ME21n transaction code type is NB and Purchase requition and line item must enter. without entering those columns it gives the error. That is userexit. How to write the user exit. Please help me.

Regards

Mohan

    Mohan,

    Then you have to develop the field exits on those fields.

    Use program RSMODPRF, execute it and provide the data element of those fields.

    Which will give you 2 Function modules 1 for Transaction type and 1 for Line item field.

    throw an error message in thos function modules if those values are empty.

    Regards,
