PO Output for Communication, how to add specific parameters

PO Output for Communication

 

There are no parameters to select purchase orders using the po_date_approved_from and po_date_approved_to, while there are 2 parameters Release_Date_From and Release_Date_to.

 

Is there an explantation ?

Please could you tell me if there is a tip to make a selection using the the approbation date of an order.

 

 

If not, I could add 2 specific parameters.

But the executable is a java process I don't have source code. But I can use the PO_CUSTOM_XMLGEN_PKG package, to add restriction with my new parameters.

In the package, I know how to use a order_id parameter (using po_communication_pvt.getDocumentId() )
