I appreciate all of you guys, Priti, Jurgen, Prasoon.
Priti thanks for clarification, Standard SAP allows to delete PO even though there are subsequent document ( not sure why SAP allows it )
Jurgen, I have used Mass PO program again and entered Deletion field value = Empty whereas at the time of deletion I kept deletion field value = X. System ran program successfully with 0 errors, but no data change, But I can manually delete the from ME22N. I am not sure it standard SAP behavior
Prasoon, thanks for sharing SAP note option 1741606. is it two steps.
A. First implement SAP note then
B, Run MASS PO again
Or A step is enough where I will be able to upload the file and populate PO deletion = empty
thanks
