3750767 - ASSERTION_FAILED dump at GR/WT confirmation

In embedded EWM, summary is active for a product, and more deliveries get linked to the same inspection lot. The process is IOT4, inspection after GR. At least one delivery has an open warehouse task, while on another delivery the open WT for the total item quantity is cancelled, or total item qty GR is reversed. This action incorrectly cancels the inspection lot, and leaves the cancelled lot linked to the other delivery with the open WT. When the other delivery's WT is confirmed or when GR is posted, there is a dump:

Category               ABAP programming error
Runtime Errors         ASSERTION_FAILED
ABAP: Program          /SCWM/CL_QLOT_S4==============CP
Application Component  SCM-EWM-QM

If there are deliveries that were GR-ed before (and GR is not reversed) against the inspection lot, their stocks will remain linked to the cancelled inspection lot.
