Hi Jürgen, thx for coming back on this.
I took it from an online Skype presentation of an other IT-department, who I don't want to ask directly. They mentioned it in the content regarding the switch of the material number.
I guess your assumption is very close to reality. they called it SAP CR code resolution, so they might put the naming themselves to their own "product".
anyway it seems we have to look for our own solution as well and I will try to stay with the SAP-standard
Thx for your help
Matthias
