Bulk Storage (SU Managed) with No Mixed Storage Allowed
In Bulk Storage with SU and no mixed, i've already defined that each bin has 5 pallet (5 SU) maximum, there's an incoming material A, material A with batch X will put into storage bin A01-01 as 3 pallet (only filled with 3 SU), and then there's an incoming again for material A with different batch let say batch Y, SAP prompt an error message (Mixed storage is not allowed in storage type) while TO creation because WM putaway strategy propose to fill in storage bin A01-01 not the next bin.
Why the system suggest storage bin A01-01 not the next bin like A01-02? because i already defined that my warehouse doesnt allowed mixed storage with any combination, my requirement is only one material one batch in one bin. why SAP always look for same material whereas i already set no mixed allowed for batch or material? is there any option to fulfill my requirement? Bulk storage as next empty bin?
I think you have to change the level of total in the storage type control of bulk storage from 1 to 2 (see your first picture posted):
Level of totals information
If a bulk storage area has storage unit management, the system must keep a record of the totals information since this is needed for stock removals. The exact level within the bulk storage area for this totals information is defined by this field and by the field for mixed storage in the table for storage type control.
You can control whether or not batch information can be kept in the totals information. If you have the setting "batch-neutral", stock removals are batch-neutral up to confirmation, and, if you have stock placements, the system searches for bins where the respective material, not necessarily the same batch, is stored. If you have the setting for "batch-specific", stock removals take place with the batch specification, and, in the case of stock placements, the system searches for bins that have the same batch.
Note: The value 1 for batch-neutral is interpreted in connection with bins with non-mixed storage (mixed storage ' ') as a 2, this is, the batch information is also stored in the totals information.
In your case the system searches for a bin with the same material irrespective of the batch (vene if the Note says the contrary, but just try)
