Hi Stefan,
This is infact one of a kind requirement we have seen for ByDesign. Logistics and Finance are tightly integrated in ByD. I have not experienced any such requirement from a customer yet in ByDesign.
Could you please let me know why your client does not want Finance for ByD. If we consider production the production lot closure etc is dependent of the runs which are executed at the Finance side. Release of outbound deliveries will create Goods and Activity confirmations which will also hit the Financial side.
Cancellation of every Financial postings that is made at the customer side by Support will not be a feasible option.
Regards
Anand
