Hi Ömer,
In my system I have a similar case. I created Characteristic RCOSTELMN as equivalent of Characteristic 0COSTELMNT. It is compounded to Characteristic RCOAREA. I.e. all custom InfoObjects.
I do not suggest to maintain External Characteristics in Hierarchies. I did not enter anything here.
Please have a look at the following screenshot of the Transformation.
Note the following rules:
- DataSource field FIELDNM is mapped to Characteristic 0H_IOBJNM using rule type "Derive Hierarchy Characteristic";
- DataSource field KOKRS is mapped to Characteristic RCOAREA;
- DataSource field KSTAR is mapped to Characteristic RCOSTELMN.
Please have a look at my configuration and modify yours accordingly.
Thanks,
Sander
