Short:
When creating a Customer (Account) in Dynamics 365 PO (CE / Dataverse) it should be possible to use a number from the number range from Finance.

Long Explanation:
I need the possibility to create records in Project Operations (CRM) and while they get created, Dual Write will call Finance (ERP) for generating a number from the NumberSequenceTable. The generated number goes back to Project Operations and replaces the standard generating number of CRM.

For ex: When I create an account in CRM I don't wont to insert an account number. The account number should be generated by the number sequence defined in ERP. Otherwise my numbering sequence will not be consistent as ERP uses a different structure as CRM. Sure.. I know I could make the structure the same.. But I need the more complex structure for number sequence from ERP provides. (Different numbers for vendors and customers, ...)

When I set account number to not be required in CRM I get an error from from Plugin Microsoft.Dynamics.Integrator.DualWriteFpRuntime.Plugins.PreCommitPlugin
Exception Message: {"RecordError0":"Unable to fetch entity CustCustomerV3Entity record. All primary column CustomerAccount, values are blank - "}
