I would like to use the $group_counter for invoices. As soon as I transfer the group_counter into the number scheme I get the error message:
To use $client_counter please add either $client_number or $client_id_number to prevent conflicts
When I combine the group_counter with the client id or counter (like asked) the value of the client_counter is used instead of the value of the group_counter:
Ex. {$group_counter}-{$client_counter} results in 002-002 as invoice number.
The system will prevent any combination which enables duplicates. That is why we force a unique constraint to be included when using group or even client counters.
I understand this point. But does that mean I can’t use the Group Counter at all? But why is it offered for the numbering scheme?
Or can I use it. Which scheme will work then? I need a solution to create invoice numbers that are consecutive. The scheme does not matter. But the number must be sequential for each department separately. Unfortunately the customer counter is too short thought here, because both departments invoice the same client. So in my understanding, the group counter looks like my best solution. But it does not work.
