Exit of IDOC PEXR2002 to change the data in the segment E1IDKU3-PAIUZAWE
I have a requirement in which I need to change the value in the field PAIUZAWE of segment E1IDKU3.
Basic type of IDOC is PEXR2002 and Message type is PAYEXT.
For eg: if the value in the field is 'PP', I need to change it to '110' in the payment file generated at the application server path.
Thanks for your response.
