Hello

I am trying to interface the Fusion Purchase order cancelled line to WMS Cloud. If single line PO, by providing DELETE action for both Haeder and Line enable the WMS Cloud PO cancelled. But if the Fusion PO has multi lines and trying to cancel one of the line. Tried with UPDATE/DTLUPDATE in header and DELETE/UPDATE with line action by updating zero quantity. but nothing works. tried through Input Interface.
