It seems as if developers from SAP had been forgetting two orgvalues when establishing the authorization concept for SAP EWM.

I recommend defining the following two permission values as orglevels:

/SCWM/ORG and APO_LOC

This is achieved by report PFCG_ORGFIELD_CREATE

As a result, within all dependent roles, the values can be maintained via the orglevel popup and thus a proper role derivation shall be possible.

Permissions: orglevels for SAP EWM
