SQL: combined SELECT-command possible???

Question

Hello Experts!
in the enclosed SQL-command I'm actually selecting from table EKPO only the open POs with no reference in order-history (EKBE). Now I want to enlarge/combine this command in that way that additionally records from order history (EKBE) with a special movement type in EKBE are selected on top.
Is it possible or do need a second select-command in the Z-application???
THANKS for a response.
Regards,
Bernd

Answer 1

The result should be all open orders!
1.) no EKBE
2.) EKBE but quantity of goods receipt (WE) is less than quantity of the PO
3.) intercompany-POs (stock transport order) have other movement types (like LFS and WA) which do not effect the status of the open PO until good-receipt movement is posted in the receiving plant .
First/Second condition is realized. Third condition is the gap until now.
