multiple quant in a bin using add to existing stock stratgey

Hi,

I want to use addition to existing stock putaway strategy. I am slecting the mixed storage allowed indicator 'X' and 'add to existing stock' indicator 'X'. No SU management. I want that system should put the different quants of the same material in one bin. Once the bin is full, system should suggest an empty bin based on volume ( Capacity chek 4) . I also want to use FIFO stock removal with the same setting.

If I can put multiple quants of the same material in one bin , my problem would be resolved. If I manually try to put different quant in the same bin , system allows it. But system itself does not suggest the same bin.

Even after allowing miexd storage in storage type with putaway strategy ' I ' , system is not putting the different quant of the same material in one bin. So can you pls suggest what to do to achive the same.

In addition , system should not allow the different materials in one bin.

Pls give suggestion as early as possible. It is a critical issue.

Thanks
