Hello Pavan,
As your are using POSC don't you think system shall create HU WT task not Product WT ?
Please create :
Create HU Types
Assign HU Types to Storage Type
Assign consolidation group to Activity Area and Storage Type
Assign Hu Types for each storage bin type
Define Attributes for deconsolidation
Assign number ranges for consolidation groups
Also check with storage type,storage section,Bin Type search strategy.
