Bypassing standard driver prog and executing own logic

Hi All,

I have a sap script which gets triggered from the standard FM - 'ME_PRINT_PO'. Now my requirement is to create a new smartform

which should get called instead of the sapscript for a specific output type.

Which means that I have to bypass the FM 'ME_PRINT_PO ' and call my smartform instead . To achieve this I have to

create an implicit enhancement where I would call my smartform.

But since the implementation for implicit enhancement can be created at the beginning or end only of the subroutine

"entry_neu " in FM06PE02, the script will always get called.

How can I avoid this.

Thanks,

Faiz
