Former Member — Tue, 13 May 2008 07:04:04 GMT

Hi Experts,

I have found the list of user exits for ME21N. But i unable to find the right exit for validating the me21n fields . My requirement is that based on PO document type and plant i need to validate.

Ex: JSD is document type

if i give plant 4000 it should accept if i give any other plant for JSD document type it should give me error message.

so could u tell me the what is the user exit used for it??

<b>points will be rewarded</b>

Hi,

There are couple of ways of finding the user exits.

1) Finding through the development class

2) Searching for User-exit word in the program

3) Giving the transaction code as an input to the program and get the list of user exits.

4) If project is known, move to transaction codes SMOD and CMOD or tables MODSAP and MODACT tables.

This is the first way..

1. Goto transaction SE93 for 'ME21N', get the program name and find out Developement class from the program in SE38.

2. Goto transaction SE84 path Envir.-> Exit Techniques ->Enhancements. Give the dev. class and press the execute button.

It will give you the list of all exit available.

This is the third way...
