ORDERS05 at item level

Hi,

I have a requirement to send ORDERS05 idoc for each item in a po at creation/change/deletion. it has some enhancements and also some changes in the std idoc segment values.

this will be triggered from a custom program assigned to an output type.

My issue:

   1)  I want the idoc first to be filled as per standard logic.

               I understand FM IDOC_OUTPUT_ORDERS can be used for this, but it will send an idoc (whole PO idoc). which i dont want. I only need idoc structure filled. So that i can change and send it per line item.

Is this possible??
