any available BADI for Delta Report correction in SAP APO?

Dear Experts,

I hope you can help us on this topics:

we implemented successufully ZXCIFUSERU09 in SAP APO in order to change the location of certain PO we are transferring from R3 to APO. This is mainly needed to avoid to create in APO all the plants we are using in R3 for performance/sizing reason.

Now we are trying to apply the same logic in delta report too in order to be sure delta report will give us only the real exception and not the list of orders where via exit ZXCIFUSERU09 we changed the location.

This is to avoid delta report is showing inconsistency that are not

true .

Dop you have any idea wich is the correct exit in APO we can use to do that? we tried with method RELEVANT_FOR_COMPARE_R3_PO but this called after the comparison with R3 data have been already done and so it cannot help us.

Thank you in advance for your feedback,

Barbara
