Warehouse Management Or SU Is Active Or Not

How to know Warehouse Management is active or not in the system?

I have found Table TCURM and Field LVS_CUS to know WM is active or not. If this field LVS_CUS is 1 means WM is active and other than 1 means WM is not active. I have tried to run scenarios in WM by making this field is in active but all scenarios are running properly.

So, what is the use of this and how to control this ?

Check SPRO -> Enterprise structure -> Definition -> Logistics execution -> Assign warehouse number to plant/storage location

Check on this one and check the Plant and WM relation.

or

You have to check T320 table. This table shows assignment of IM storage location to warehouse number

In WM in SPRO, "Define Control Parameters for Warehouse Number" is mandatory to enable "SU management active"?

What is the purpose of this flag?

SU means storage units. It's a different concept in WM wherein you maintain materials in containers (boxes, pallets...etc). These containers are numbered and have SU IDs, they have their type (the sizes of container) which is SU Type, all these terms are integrated in SU management. Only if your business scenario invloves such type of units you need to maintain SU active.

SU management check box is NOT recommended to be activated for interim storage types.

You can make a whole Warehouse as SU managed or you can define it by Storage type too. Once you make a storage as SU managed, along with the Bin, the stock also gets updated on a Storage unit.

If you have a warehouse with pallets, you can define one pallet as a SU and the palletization data will be defined in the Material Master (Warehouse view 2).
