So far there was no tolerance in delivery document.
Hence more material was received and moved to warehouse.
GR is done in EWM with 120 qty but PO and Inbound delivery in ECC is of 100 qty.
Due to which there is failed queue in SMQ2 i.e system is not unable to communicate back to ECC.
Please suggest if any one of you have came across such issue.
Thanks in advance.
