Bin Lock for Previous task creation prevents the next WT creation to the same Storage Bin in EWM

[gokugarv07]

Fixed Bin Storage Type EXPH is created to putaway certain products. When the delivery containing these products is completed all the Warehouse tasks get created parallely. However when we check the WT's we find the only couple of tasks are created to the EXPH storage type rest are created to the following storage type EHPE in the putaway search sequence. This seems to be happening because of the Fixed Bins are already under process. Any suggestions how can we mitigate the issue and not do a total havoc in the warehouse setup.

Hi,

We had the same problem. We fixed it by activating the following:

SPRO - EWM - Cross Process Settings - Define General Settings for Parallel processing and Perfomance - Check the last checkmark box "One Proc.".

This solved the exact same issue for us. Hope this helps.

Kind regards,

Ozgur

Hello,

Your bin must be getting locked by a parallel process as multiple Warehouse task is getting created for the same bin. This happens because parallel processes that try to use the exact same destination bin, however, an exclusive lock is put on the bin by the first process. In EWM, there is no wait mechanism to process the executed iteration sequentially( Process Task one by one using some wait mechanism) unless you do some changes in your system, either by changing PPF execution or using a badi. There is a SAP note for the issue, its worth to review it and opt the correct option.

May be something do with system performance. However you can also try one more option, define item filter (max 1 item) on warehouse order creation rule, you can do put away by queue.

Thanks and Regards,

Hi Prabhakaran, I set the item filter as max 1 item but still the system response is same.

Thanks.
