Decentral EWM : Backflushing from EWM storage location for repetitive manufacturing

[ravihari67]

We are working with S/4HANA 1709 with Embedded EWM.

For repetitive manufacturing process, we observe that the parts used for the production order cannot be backflushed from an EWM storage location. This is described as a restriction in the S/4HANA 1709 (OSS note - 2494704) . The same restriction seems to also continue in S/4HANA 1809. ( OSS note-2668150).

The description in the OSS notes mentioned above seems to indicate that these restrictions exist only in the Embedded EWM setup.

Can somebody clarify whether Backflushing of parts for repetitive manufacturing happens from EWM storage location if we have a Decentral EWM system?

We are in a similar situation in our implementation. If we are using Repetitive Manufacturing backflushing with embedded EWM, that means that none of the production lines can be EWM managed? Can you please provide a solution for how to manage the storage locations?

As far as I can tell, the production line would need to be IM managed and then have an outbound posting change in EWM (triggered by process order, KANBAN, etc.) with an automatic PGI setting to transfer the stock for production after the materials have been moved to the PSA. Is there a restriction on how many fixed bins can be assigned to the PSA in case we have bins that need to be managed in the PSA?

Hi,

We have the following situation in company which I work:

Kanban materials has maintained control cycles in transaction PKMC. The PSAs for those control cycles are also created in EWM system (SCWM/PSA) and mapped in transaction SCWM/PSAMAP. PSAs are assigned to the (non EWM) IM storage location. There are created storage bins in PSA storage type (SCWM/LS01). Single PSA in EWM can have more than one storage bins (SCWM/PSASTAGE). The replenisment is execute by transaction PK21 in ERP system. After scanning of kanban barcode the ERP system creates outbound delivery. In reference to this delivery the EWM system creates warehouse order for picking from EWM warehouse to PSA. After several minutes all of stock delivered to the EWM PSA storage bins are automatically posted to the IM storage location (movement 411). The last step is posting the 261 movement by backflush indicator. The relevant stock is consumed by backflush depending on the production order quantity.

Best regards,

Marek

Hello Marek,

Thanks for the details, i am trying same scenarios in our system,

I am trying to create PSA with IM location, it always comes up with message the source storage bin has to be EWM managed, i am not sure how you made this setup

PSAs are assigned to the (non EWM) IM storage locationt.

would you be able to throw some light on this. many thanks in advance,

Regards
