Storage Bin Allowance by Material

[former_member606141]

We have the below requirement and are curious if there is a standard solution:

Storage Units/Handling Unit of Material 123 is put away in Storage Type A1

When Material 123 is stored in A1, only other storage units/handling units of material 123 are allowed to be stored at A1 until the bin is emptied of material 123. Multiple different batches of this same material, however, can be in this storage bin. Then any other material number is allowed to be stored at storage bin A1.

Dependencies are that many different materials use the same packaging material that uses the same Storage Unit Type to the restriction on storage unit type on the storage type does not fulfill the requirement. Bulk storage is not a possiblity.

The requirement is to have some sort of dynamic storage bin allowance by material.

Does this setting exist in SAP standard or would this need to be accomplished by a userexit.

Hello chbright1

You are right in your comment of mix storage control not being suitable solution here. I have mentioned it just to show there is a possibility to control mixed storage on storage type level. I'm positive you can implement your specific requirement with MWMTO003. Just take your time to understand how the 4 functions of the enhancement work together and make sure to implement both automatic determination of the destination storage bin as well as validation of a storage bin entered manually.

Hello chbright1

The way I understood your questions is that you need to restrict mixed storage on storage type level. Although mixed storage settings are indeed set up in storage type configuration, they are executed no storage bin level, i.e. the system check that you don't mix different stock in a storage bin, but it doesn't check that for the entire storage type. The check on the storage bin level is usually just fine for the most common business scenarios. Yours is pretty specific. As such you can implement that with a custom stock placement strategy, user exit MWMTO003.

Thank you 3a9e4ce873a94034b33dc62b0ce600ee !

Unfortunately, multiple batches of the same material are allowed on these storage bins. Not allowing mixed storage requires the material and batch to be the same across all storage units to my knowledge...

I will take a look in to the User Exit that you suggested because I believe this requirement is too specific for SAP standard.
