Hello Sathish,
i found the necessary rules/ filter in the customizing for one warehouse order for severals inbound deliveries. These are the relevant settings:
SPRO> EWM> Cross-Process Settings> Warehouse Order>
-Define Sort Rules for Warehouse Tasks: SortFields= NLTYP and AAREA
-Define Filters for Warehouse Order Creation Rule: Filter Type= Warehouse Task; Filter Type= Filter at Item Level; unmark only 'No Putaway'
-Define Limit Values for the Size of Warehouse Order: Limit Val. Type= Warehouse Task; Max. WTs per HU=1
-Define Creation Rules for Warehouse Orders: Create WOCR with Creat.Cat 'B Pick Path' with the previously created Rules, Filters and Limits
-Define Search Sequence of Creation Rules for Activity Areas: assignement of WOCR to the relevant activity Areas.
If now a HU in goods receipt is delivery across packed (item from severals inbound deliveries) and then has to deconsolidate, it is created for the HU one warehouse order with one warehouse task.
