SAP EWM: Outbound delivery with returnable packaging material SMQ2 error

0 Kudos


I have created a scenario in which I have an outbound delivery, in which I am adding a returnable packaging material.

The problem is that when I do a goods issue, queue is getting stuck (SMQ2) with error "Error while determining for WM via table 156S:621 ///L/X/".

Any clue how to solve the issue?

We are using S42021.

the settings you are looking for can be found in SPRO under MM / Inventory Management ... / Movement types / Copy, Change Movement Types.

If you read the error message "from left to right" the system is missing an entry for 621 - blank - blank - L - X

This corresponds to the following columns of the table:

  • Movement type - 621
  • Value update - blank
  • Quantity update - blank
  • Movement indicator - L
  • Receipt indicator - X

You can see there is no such entry, hence the error.

As you cannot add any entries to that table in SPRO I am quite sure you are trying something that SAP has not intended you to do.

How to stock manage your returnables? Are you keeping them in a MM-managed or WM-managed storage location? My guess is "WM-managed", because only then is makes sense to try to find a WM reference movement type.

Remark regarding "classic WM": on the ERP side the EWM integration also uses the WM reference movement type (column "Ref" in table above). This is used to "organise" stock movements which normally do not involve a delivery, i.e. movements posted in MIGO. The MM movement type in MIGO has a WM reference movement type assigned to it (621 in the table above). That reference movement type is then used in the table below to determine a delivery type (DOG for 621). That delivery type is then used to create the delivery which is needed to communicate with EWM.

it means you should probably look for someone in your organization with WM knowledge? Because that is classic WM.

The item category which was determined in ERP is connected to a schedule line category. From this one you get the movement type 621.

Then the system goes through the tables to find a reference movement type. Now besides the 621 I would expect an x for value update and an x for quantity update? But not sure about that. I think that L says that it is a goods movement for a delivery note, the X a stock transport order? (is that what you are doing?)

Once the reference movement type is found, the system will also try to find a WM movement type. Which does not do anything, but this is simply how it works.

But yeah, you need someone who can look into your WM tables.




All the above is no official SAP statement.
