User exit for populating custom fields in BSEGC table.

Hello,

We have to enhance the BSEGC table to add 2 custom fields. We will also be adding those in the IDOC WPUBON01 under segment E1WPB01 and sub segment E1WPB06.

We need a user exit what will allow us populate the 2 fields in the BSEGC table.

Regards,
