3543344 - How to replenish same product of different batches on the same bin in EWM

During planned replenishment system will never actively create a mixed stock situation, even if allowed in customizing.
Such mixed stock prevention is mentioned with slightly different words on KBA 2409948 - Mixed storage of different batches in same bin not working.

Therefore, if product X has batches A, B and C they will be putaway'ed into three different bins (if there are enough bins to perform addition to stock or empty bin), otherwise as soon as system tries to putaway product X with batch B to a bin where a different batch is stored, the warehouse task creation will fail with error:

"Product/batch check: Mixed storage in HU/bin &1 (storage type &2) failed
Message No. /SCWM/HU_WM150"

However, the expectation is that planned replenishment in /SCWM/REPL should consider the same bin for putaway of a given product that have multiple batches.
