Bulk Putaway Strategy

Hi,

I have a query relating to the determination of bins for my bulk putaway strategy.

On my bulk storage type I am using putaway strategy B (Bulk Storage) and mixed storage indicator C (several batches per bin only SU bulk storage)

Having generated a putaway the system successfully denotes next empty bin until capacity as per the block structure under OMM4 is full. So far so good however it does not then allocate the remainder of the putaway to a bin where the same product is house although a different batch. (ie the error message below appears)

System message L3 009

No destination storage bin to be found in storage type 004

However i can manually denote a bin where there is already the same material but with a different batch. The system then allows this entry.

Does anybody understd why the system would not automatically select this bin which should be ok?

Any ideas appreciated.

many thanks,

Adam.
