Modification of a field in an IDOC

[Former Member]

Hi,

I want to modify a field in a standard IDOC. For eg., I want to change a vendor starting with "A" to one starting with "B" like A001 to B001.

I would like to know how should I use conversion rules for the same. Where are they defined? And what is the procedure?

Thanks,

Kshitija.

you need to program into an user exit.

When your segment is filled you can program the user exit and change the value of the segment.

What idoc, segment and field u need to change?
