Storage type determination with inhomogenous / mixed storage units

[theinternets]

Hey there,

so i have this mixed storage unit containing 5 materials that all have their own putaway storage type indicator in the material master. If I try to move the storage unit (LT09 or FM L_TO_CREATE_MOVE_SU), the System will determine a destination storage type and bin. It seems that it's determined by putaway storage type indicator of the lowest numbered quant in the storage unit.

My questions:

1. Is my assumption (lowest quant number determines storage bin) correct?

2. If so, is there any way to influence this behaviour (apart from user exits)

Cheers

Hello theinternets

First of all it seams odd to put materials with different destination storage type search strategies on the same pallet. Different destination storage type search strategies mean that materials should be placed in different storage types usually. Yet you put them on the same pallet that by definition needs to be placed in a single storage type.

I'm not aware of any setting in WM that would allow you to specify which quant is used for storage type search in case of mixed storage units. To my knowledge storage type search strategy is implemented with the NACHTYPE_ERMITTELN FORM routine in the L03A function group. So you can debug that if you need to.

If the standard destination storage type strategy doesn't work for you, you can implement your own with the EXIT_SAPML03T_002 user-exit.

Hi Dominik,

it's a deliberate misuse of the Handling Unit structure (too specific to be explained here). Some more testing seems to confirm my initial suspicion - I will have a look at NACHTYPE_ERMITTELN, however, thank you very much for that!

EXIT_SAPML03T_002 is always an option for sure - i just wanted to make sure that I exhausted every standard-functionality before going down that route.
