How to modify existing active user-exit

1381 Views

Hi all,

I have in the Production system, the user-exit for customer-specific data for Purchase Order EXIT_SAPMM06E_012. The include ZXM06U43 already contains some code which is running perfectly.

I need to append some more fresh code in this include. I have tried to use SE38 to change this include. But after appending the code, if I am trying to activate it, I encounter the following error message

"Field "" is unknown. It is neither in one of the specified tables nor

defined by a "DATA" statement."

I am only trying to apply conditional statement on a field which is a parameter given by the exit.

What could be the problem. What are the steps involved in modifying an existing active user-exit. Am I missing any one of those.

Thank you for your responses & time.
