Enabling Classification Key (OPORD) field in DFKKKO

Hi SAP Experts,

In the table DFKKKO (FICA document header), the classification key field OPORD seems to be activated through enhancement activation from IMG path

SPRO-->Financial Accounting (New)-->Contract Accounts Receivable and Payable-->Program Enhancements-->Prepared Enhancements-->Classification Key.

In my project system, this field is already activated from the above said location. But this field does not appear in transaction FPE1 (Post document) but can be seen in FPE2/FPE3 only if field has any value. Now the requirement is to show the classification key in FPE1 transaction as sometimes the user will have to populate value into this field.

Found through debugging about the function module FKK_ENHANCEMENT_STATUS_CHECK which actually looks at the ACTIV indicator in the table TFKENH. Now this table is a system table and cannot be modified by customers.

Any idea on how to activate the indicator in table TFKENH or how to make the classification key field available for input in FPE1 transaction?

Thanks in advance.

Thanks,

Sakthi.
