While we are able to import PO header and lines using data entities, I am looking for a way to import these documents together . We would like the system auto assigns the PO number, We have lots of user created POs in the system and we would like to use imported POs also to use the same sequence. Is it possible in this scenario where system will create the PO number(which it can) but reference this newly created number in the lines file that is also being imported in the same project simultaneously? thanks
