Thanks Anil for providing this note.
This is a consulting note, so I also checked with SAP by opening an OSS message.
I was advised by SAP that i can apply this note in my system, however ... since it is a consulting note, i can not expect any more support from SAP on this.
So now i have decided to use BBP_PD_PO_CREATE FM for limit/material POs.
