3566890 - Dump ASSERTION_FAILED in /SCWM/CL_GOODS_MOVEMENT during GI

After posting Goods Issue for an EWM Outbound Delivery with active parallel processing, the Goods Issue link(s) may be missing from the Document Flow.

Symptom 1: When the user repeats the Goods Issue posting, processing will be terminated with Runtime Error ASSERTION_FAILED in the ABAP Program /SCWM/CL_GOODS_MOVEMENT=======CP.

Source code extract from the Runtime Error:

   51   IF lt_stock_loc IS INITIAL.
   52 * try to get stock location table from buffer
   53     CALL FUNCTION '/SCWM/STOCK_LOC_GET'
   54       EXPORTING
   55         it_doc         = lt_doc_id
   56         iv_read_buffer = abap_true
   57       IMPORTING
   58         et_stock_loc   = lt_stock_loc.
   59   ENDIF.
   60
>>>>>   ASSERT lt_stock_loc IS NOT INITIAL.

Symptom 2: Alternatively, if the item is Serial Number managed, the delivery may be blocked with error "Serial numbers needed for product &1" (/SCWM/DLV_SERIAL205) upon using the Check button, or when trying to post GI again.

Symptom 3: The GI status of some ODOs assigned to a TU is still "Not Started". When trying to post GI of TU, it is failed with the error "Required handling units could not be found, Message no. /SCWM/HU_WM015".
