It is very useful to have overridenumberseries on several endpoints. But we have customers with POS systems where we want to import the receipt number into Visma.Net. The easiest and safest way, to avoid duplicates and to simplify searches, is to use the referenceId field for the receipt number.
There is already a setting for the possibility to import manual numbers in the number series setting. What is missing is the overridenumberseries option. This applies to both CashTransaction and CashSales.
