In this article I will share some handy information about SAP Storage Unit Management.
What is Storage Unit Management:
SAP developed Storage Unit Management concept to enable warehouse management to identify the container that holds a material as it moves around the warehouse. Storage Unit Management was developed exclusively for WM, and from it SAP developed Handling Unit Management for MM. There are slight differences between the two, as we have seen earlier .I am noting them as below
1)Handling Unit Management allows for the nesting of Handling Units i.e., a Handling Unit containing a number of other Handlingn Units, while Storage Unit Management does not allow nesting of Storage Units.
2)Handling Unit Management requires that an item be unpacked and packed, while this is not required for Storage Unit Management. The Storage Unit is used to contain a quantity of material for its movement around the warehouse.
In SAP ,Storage Unit Management configuration is done as follows :
First need to activate SUM at warehouse level
Menu path: IMG * Logistics Execution * Warehouse Management * Storage Units * Master Data * Activate Storage Unit Management per Warehouse
step 2 SU Number range-
Define SU number ranges:- Menu path: IMG * Logistics Execution * Warehouse Management * Storage Units * Master Data * Define Number Ranges.
step 3 :Activate SUM at specific storage type level-
Define Storage Type Control:- • Menu path: IMG * Logistics Execution *Warehouse Management * Storage Units * Master Data * Define Storage Type Control.
You need to consider some of the below settings that influence SU management-
1) SU mgmt active: This indicator is set to show that storage type is SU managed.
2) Putaway strategy: This is set to P, which means that the SU type putaway has been selected.
3)Mixed storage: Different materials can be moved on the same pallet as a defined SU.To do this the mixed storage indicator must be activated.This depends on business requirement.
4)Full stk rmvl reqmt: If this indicator, is set, it affects the complete SU. A full stk removal means complete removal Storage Unit regardless of the required quantity.
4)Define Storage Unit Type:- Menu path: IMG * Logistics Execution * Warehouse Management * Master Data * Material * Define Storage Unit Types .
For SU management activation we need to have palletization data maintained in material master .This palletization data is linked to storage unit type .We also need to maintain bin type data. The bin type is the different types of bins available in the warehouse. The Bin type is assigned to requisite Storage unit type giving system information about which Storage unit type can be stored in what bins
Picking with SUM:-
Following are methods used to do picking with SU:
Complete Stock Pick: The entire storage unit can be picked for a GI even if the
requirement is for less than the quantity in the SU. We need to set configuration in
storage type. Menu path: IMG * Logistics Execution * Warehouse Management *
Master Data * Material * Define Storage Types. Make sure “Full stk rmvl reqmt
act” indicator is set.
Partial Stock Pick: If full stock removal is not set in storage type configuration then partial stock picking is possible.
Complete stock Pick with Return to Same Bin: If “Return stock to same storage bin” indicator is set in configuration of storage type.
Partial Stock Removal Using a Pick Point: If indicator “Stor.type is pck pnt” is set for storage type. Then by removing SU from a pick point, the SU information is not lost, as it would be if the material was removed to an interim GI and then a partial amount was returned to stock. When TO confirms a qty of material, system posts the remaining qty from SU to pick point. The remaining material from SU can be moved back to the org. storage bin or to a new storage bin.For this we need to create a pick point storage type .
