For those who are looking to create a new number sequence (say, for a new module), there are many references available online.
However, I could not find the last thing that I wanted to do: Put a specific prefix on the number sequence. It appears to default to the first four letters of the module’s name: Accounting sequences begin with Acco_ and our JointStuff sequences began with Join_. We wanted JVA, our prefix used elsewhere, instead.
This is set from the base enum NumberSeqModule.
Go to the specific value that you created
And change its label to simply the prefix that you want:
Then, your number sequences will be prefixed (segmented) with the code that you want. Note, too, that it also specifies the “Area” in the number sequences screen.
