WM Source bin not determined automatically during pick

Hi All

For GI to delivery, when I do pick using LT03, system does not populates the source details automatically:

I think, it is because the SUT is not populated automatically

But, the palletization data is maintained for the part:

Also, Storage type check is active and indicator maintained correctly

No storage section check is active

for storage type 210, all SUTs are allowed

Also, when I manually enter the SUT as AA in the transfer order, system picks the bin from 210,

but does not populates the QUANT & SU number:

In LS26, there is a enough stock available, all with Quants and SU numbers in GATE1 bin

Please suggest!

Best Regards
