Parent licence plate information in F4611 when there is single Parent child relationship

Hi,

whenever there is single Parent child LP relationship, the Parent license plate number is not getting updated in F4611.PLPNU(Parent license plate) after pick slip suggestion. After pick slip suggestion, the parent license plate gets updated in "From license plate number" (LPNUF) and also in "To license plate " (LPNUT).

fyi -when there are multiple child LP on single parent LP, then Parent license plate number is getting updated correctly in F4611.PLPNU and child license plate gets updated in "From license plate number" (LPNUF).

Issue is when single Parent child LP relation exists as mentioned above.

Can someone confirm if this is standard behavior?
