Problem with BAdI ME_PROCESS_PO_CUST

Hi,

I have a "tiny" problem with BAdI ME_PROCESS_PO_CUST.

I do some checks in Method CHECK and want to output a message regarding the whole PO (not for a specific item).

The message is displayed in the protocol - but in the last PO item section above the appropriate item schedule message.

But my message is not item related.

I can not do the check in the PROCESS_HEADER because I need the total qty of all items to do my check.

What do I have to do to let my message be displayed in the protocol above the first po item information - as a Header Information ?

Thanks in advance

Britta
