I'm using the Attribute Assistant add on to try to achieve this task. Is there an expression that I could write in the DynamicValue table so that the tool looks at the subtype field of a feature class and then determines which Sequence that it needs to use?
For example, I'm working with a dummy valve feature class where there are two subtypes : 3 and 6.
The largest Subtype 3 valve ID number is 0107910, and the largest Subtype 6 valve ID is 1702300. How can I get the tool to update these two ID numbers independently but within the same feature class?
