The new feature Credit Management, once activated, adds some new menus. The error is in
"Credit and collection parameters" , the Tabs from top are named
- Collections
- Credit
- Number Sequences

The german Translation is incorrect. The Parameter String says "Parameter für Kredit und Inkasso"
the fields show
- Inkassi
- Haben
- Nummernkreise


Please update the "Haben" into "Kredit"
Then, the tab-list should read
- Inkassi
- Kredit
- Nummernkreise
