LOSC with multiple interim LBs

Hi all,

I am facing issues with LOSC.

Item is requested for staging from storage type A to storage type E.

Picking is required, so EWM creates interim LB for HU from storage type A to storage type D.

The HU needs to be handed over via handover point, so another interm LB for HU is created from storage type A to storage type C.

Those LBs are created correctly.

Before the HU can reach the hand over point, it has to pass an elevator, so another interim LB for HU should be created from storage type A to storage type B.

Because I like drawing pictures, here the visualization of the as is and as should be situation:

As is:

As should be:

Somehow the system only creates a maximum of two interim LBs, so 3 LBs in total.

Can anyone explain to me why this is happening and a way on how to solve this issue?

Thanks in advance and best regards,

Benjamin

Hi Benjamin,

first task is a product task for pick-point, and losc would be

From A to E via D.

For second LB try to set

A to D via B.

You should have in this case

  • LB1 Picking Task in stauts B
  • LB3 HU Task A to D in status B
  • LB4 A to B active.

when LB4 gets confirmed system tries to activate LB3 and here you need a LOSC record B to D via C. Istead of activation you get your LB2.

This should work

Hi Daniil,

thanks a lot! Thats my desired solution! I was focused on creating all LBs in advance rather than have a look at the actuel material flow.

So SAP Logic to prohibit the creation of a third inactive interim LB totally makes sense.

Hi,

if you use LOSC, at first there only should be the LB1 and LB4, LB2 and LB3 would only be created during the processing.

Maybe it would help to see your LOSC setup and also what storage type roles you have there. Does "handover point" mean that this is a storage type with the role pick point? Not sure if a scenario with an additional interim point is then even possible.

All the above is no official SAP statement.

And it is EWM. NOT eWM - Duh!

And if your question includes the word "transfer order" - do NOT tag the question with Extended Warehouse Management!

Hi Jürgen,

Thanks for your reply.

From my understanding LB1 and LB4 would be the only LBs if we work with complete HU movements. So interim bin for relation A to E would be B. In my scenario I need to transport the complete HU on 3 different resources before it can even be picked.

Here is some more detailed information about config and the logistics scenario:

A has storage type role ` ` regular storage type – and active pick point

B has storage type role ` ` regular storage type – no active pick point and level of av. Qty on bin level

C has storage type role ` ` regular storage type – no active pick point and level of av. Qty on bin level

D has storage type role `C` as ID- and P-Point

E has storage type role `D` as staging area

Here a simplified visualization of my losc config:

Furthermore I tried to debugg a little bit and found out that in function module /SCWM/ROUTING_LAYOUT_CHECK there is a parameter IV_ROUTETO which gets a new value each time the FM is called.

First it is blank ` `

Second it gets value `1`

Third it gets value `X`

In line 61 of this FM there is a check if IV_ROUTETO is differenct to constant WMEGC_ROUTETO_LAYOUT which has value `X`.

That means for my understanding that SAP prohibits the creation of more than 2 interim HU LBs.

This ist he material flow from Resource Perspective:

Rsrc 1: Pick up in A, place in B

Rsrc 2: Pick up in B, place in C

Rsrc 3: Pick up in C place in D

(Rsrc 3a – not rel for LOSC: Performs Picking and packing in D, closes HU)

Rsrc 4: Pick Up in D and place in E

Thanks in advance and best regards,

Benjamin

hi, can you try to make configuration as below:

SAP Logic, System use source and destination location of warehouse task and compare with configuration. If there is an intermediate locations in between, System creates 2 tasks:

Task 1: Source to intermediate locations.

Task 2: intermediate locations to Destination.

HI Ngan,

thank you very much for your input. But unfortunately this would not work in our scenario. Because we can not perform actual picking in B. Picking is required to happen in D, directly before staging. I guess this would work if we have complete HU movements.

We have multiple resource changes in this scenario.

Pick Up 1: A to B

Pick Up 2: B to C

Pick Up 3: C to D (Here picking happens)

Pick Up 4: D to E (Final staging)
