Why for Bulk putaway strategy does mixed storage not need to be set
I have setup a storage type to use bulk storage for putaway. I only have addition to stock flagged and not mixed storage. This actually allows me to move different SU's into the block storage until the full capacity is met which each time creates a new quant for each new SU. Now this is what confuses me....because a new SU is a new quant.
Per the SAP definitions you need to flag the Mixed Storage if you wish to add additional quants to a bin so why does SAP allow this if I have not flagged mixed storage?
I would expect that as I only have addition to stock flag the system would actually only allow 1 SU in that bin and never accumulate as another SU is considered as a new quant so the system would propose another bin.
To confirm this I created another storage type which is SU managed and set it up as manual placement flagging only 'addition to stock' and not 'mixed storage'. I then tried to move a SU into existing bin with the exact same material and attributes packed in a SU and the systen gives the error 'Mixed Storage not allowed'. Now this makes sense as it wanted to create a new quant and its not flagged to allow it.
So why is it ok that for bulk it adds new quants if mixed storge is not set?
Thanks for any feedback
