Mat-to-Mat posting with consignment stock

819 Views

Hello everybody,

we have the following, simple situation:

We want to perform a material to material posting with consignment stock. Nothing else.

When trying this, we get the following error message:

As I know, the movement type is determined by the /SCWM/TIMB* tables. In most cases, when posting something, initially posting string reference 411 is found according to /SCWM/TIMBWA. As we are just posting material to material unrestricted, we should usually get the posting string reference 309 according to /SCWM/TIMBWAXTRA. But /SCWM/TIMBWAUSG determines 311 as PSR, when consignment stock is posted with PSR 411 (without changing the consignment stock usage - usage: C to C).

AND it looks like the system takes /SCWM/TIMBWAUSG earlier into account than /SCWM/TIMBWAXTRA. Otherwise, we wouldn't end up with 311 in our case.

Now, we get to the core of the problem:

The TIMB-tables are system tables and therefore not to be customized. We should instead use the customizing transaction "Define Customer-Specific Movement Types". So in our case, we would connect the PSR 311 to Mvmt-type 309 to get a proper posting.

BUT, in /SCWM/TIMBWAUFC, field combinations for posting changes are defined for the posting string references. Here, it is defined that 311 doesn't allow product changes and 309 does. But these is also taken into account when customizing the Customer-Specific Movement Types and we get the following error message when trying to connect 311 to 309:

My question to you guys: What can we do to make mat-to-mat posting with consignment stock possible, without changing SAP own system tables (and probably mixing up the whole movement type determination...)
