IDOC_INPUT_ORDERS with error message RV45A-VBAP_SELKZ (2) is not input fiel
I am creating a multiple line sales order from Idoc and using the FM IDOC_INPUT_ORDERS. The idoc is processed with status 51 with error message RV45A-VBAP_SELKZ (2) is not input field.
It only happens for Idocs that are processed 1st time (re-processing is succesfull) and only in the background (if processed first time in foreground - it is ok).
Have you ever seen this message?
