PCW call custom task after approval process

Hi comunity,

I need to know how could call a custom task from PCW. Because I need to update a Z log table after the users approval SC just when the document is set to approved. I've checked the WS40000015, but seem to me that this is not possible.

I have no other option to use the BBP_DOC_CHECK_BADI to do so? Am i right?.

Regards.
