Block Storage Defination
Storage unit Management setup -This article describes the Block Storage Definition .
If you are integrating HUM with WM i.e implementing Handling unit management in a warehouse managed storage location , you will need to activate SUM in the storage type where you will store the Handling units. The handling units become storage units in the warehouse.Most commonly Storage units are stored in Bulk storage types . This is because the storage units can be pallets which are bulky and thus cannot be stored in conventional bins. The bins could be racks with capacity to hold more than one pallets or like.
In such a scenario we need to tell the system what is the spatial arrangement of the bin.i.e how does the bin store the SU (storage units) .So when you use a bulk storage type you need to make this additional setting called “Block Storage Defination” . This is true only for bulk storage type. And this is a mandatory setting.It tells the system how many storage units of which storage unit type can be stored in each storage bin type.
If you do not define this , you will hit an error “missing definition for block storage control” while doing put away .
Here is how the setup is done.
The Tcode is OMM4 .
Define Block Structure
Maintain an entry here with your warehouse number & storage type as follows
Whse No, St. type, B1, E1, bulk storage indicator, stacks, stack height, No. SUs ( No. of SUs = stacks * stack height )
Along with this you also need to define storage type control for bulk storage
Following is the meaning of each field-
If you want partial qty placement in bins, you can check “partial qty mgmt”.
If you want to combine different items into single TO, you can check “Combined Placement “.
If you want to block the row (storage bin) when the first transfer is made, you can check “Blocked for putaway”.
If you want to keep track of the total quant count when storage unit management is active in WM, you can give 1 or 2. This 1 or 2 selection has a significance if you want to have the totals information stored by the system. for eg in batch managed stock, 2 means system will store batch specific information. This is particularly important when we are pick stock from a particular bin and would want the system to point to the exact batch available in a particular bin.
Note that in a bulk storage type , system assumes that you are interested in the system pointing to a bin with the required batch and not the exact batch in that bin. Hence when system presents a TO for picking , it will show the bin in the TO and the operator is supposed to pick any SU from that bin (that is the essence of calling it bulk storage)
Also ensure that you have defined- Bulk storage Indicator for your warehouse in OMM4.
