Stock on bin assigned to different storage locations and moving inbetween these?

Hi all,

our colleagues from ERP S4 HANA project are planning to use different storage locations to seperate stock for specific customers from stock available for everybody in future. So the result should be some kind of reservation one can say, but as we had several troubles with reservation itself in the past they want to do it the described way.As we also plan to implement EWM in future, but I have honestly not that much knowledge currently about it, we would like to avoid any troubles with this solutione then in the future on EWM side.

So please imagine following situation:

There are 50 pcs of product A in WH A001 in storage type 1000 in Bin 1001-01. All 50 pcs are located on storage location 0001 in plant 0001.Now a specific customer announces that we would like to order 10 pcs.Colleagues now want to move the stock of 10 pcs. from storage location 0001 in plant 0001 to storage location 0002 in plant 0001.From warehouse operational point of view this does not matter. We want to keep all 50 pcs. on bin 1001-01 in storage type 1000 of WH A001.

So now the questions:

Is it possible to "ignore" the movement on storage location level in EWM or perform the movement in a way that it does not impact EWM or at least is automatically?Would one even have an information in EWM (e.g. in the monitor or somewhere) that the 50 pcs. are located on different storage locations in ERP?

Thanks for any hint

Hi,

The first thing you have to consider is that you have to allow mixed storage in the storage type. As you keep the 40 + 10 pieces in the same bin, but they belong to different storage locations, this is necessary.

The question is how you want to do this posting change? If you trigger it from the ERP side, the system would create a delivery which is sent to EWM as posting change (delivery) and the posting change will have to be confirmed in EWM. That can happen automatically, but you have not standard way to influence the bin in which this happen then. The other way would be to do the posting change directly in EWM, there you can select the bin and change the the storage location (resp. that will be the stock type) for the required quantity.

For a warehouse point of view of course this does matter as it effects the quants you have in your stock. Maybe not from an operation point of view, but you will definetely see in the warehouse monitor that you have stock of different storage locations in one bin.

Hi Jürgen,

thanks for your answer.

Ok. Mixed storage should not be an issue.

I suppose the change of the storage location would be triggered from ERP, as they have the information first and automatically can trigger it. As we are talking about multiple such actions a day (means several hundreds) I guess doing it manually in EWM would not be feasible.
I understand in your comment, that a change in the ERP storage location would correspond in a different stock type in EWM, correct? Would this then mean I need one stock type per storage location I use to differentiate the parts? (e.g. if I have storage locations 0001 to 0010 to differentiate I need 10 stock types in EWM?)

Further topic I do not understand:

You write that

"If you trigger it from the ERP side, the system would create a delivery which is sent to EWM as posting change (delivery)..."

In fact movement from storage location to storage location would not be a delivery, but an MM movement with material document.

So ERP would sent some kind of transfer request instead of a delivery. Is this correct or do I miss something here?

Thanks again for your help!

Regards

Michael

Hi,

"As we are talking about multiple such actions a day (means several hundreds) I guess doing it manually in EWM would not be feasible."

If you check how the process is done in EWM, you would probably see that it does not take longer.

"Would this then mean I need one stock type per storage location I use to differentiate the parts? (e.g. if I have storage locations 0001 to 0010 to differentiate I need 10 stock types in EWM?)"

No... it means you need usually 40 stock types in EWM. Because you might have unrestricted stock, blocked stock, quality inspection stock and return stock. In each storage location. Each combination is a stock type.

"In fact movement from storage location to storage location would not be a delivery, but an MM movement with material document. So ERP would sent some kind of transfer request instead of a delivery. Is this correct or do I miss something here?"

If you trigger this from ERP, this will always be a delivery. You can not have a direct MM movement from ERP to EWM. And there is no "transfer request". Only a warehouse request, and this is a delivery.

Recommendation: have a look into EWM before you have any more discussion how to solve this.
