Attach User exit to standard T-Code

[Former Member]

Hi friends,

I would like to know how to attach User exit program to standard program/Transaction.

We are using KO01 Create Internal order in which we want to control the naming convention of the Internal order numbers.

The Number range has been already defined as external in the Order Type.

For eg.

We have a policy of prefixing the country code before the internal order number.

Order belongs to UK start with UKXXXXX. The system should give an error to user while creation if UK is not entered.

Please help.

Hi,

Please check the below exits:

COOPA002 - Customer function for master data maint. - internal orders

COOPA003 - User-Defined Fields in the Order Master

COOPA004 - Customer function: Print order master data

COOPA_01 - Customer check modules for internal orders

I also met the problem. I'd like to check whether the data is correct or not, use "COOPA002".

If the data is not right, I write:

message e021(f1) with 'Error'.

But nothing happened! The error data was saved.

Why?
