Attribute Assistant - generate unique id based on domain value in another field

JonKwong1 — Wed, 24 Jun 2020 08:39:09 GMT

I have parcels with different landuse classes: Business, Residential, etc. I would like to generate a unique id when the parcel is being split. However, I need to generate a different id and counter depending on the landuse class. If Business, then generate B1, B2, B3, etc. If Residential, then generate R1, R2, R3, etc.

This is my progress.

Table Name	Field Name	Value Method	Value Info	On Create
Parcel	PLOT_ID	GENERATE_ID	COUNTER_B	TRUE
Parcel	PLOT_ID	GENERATE_ID	COUNTER_R	TRUE
Parcel	PLOT_ID	EXPRESSION	IIf([TYPE]="Business","B" & [PLOT_ID],"")	TRUE
Parcel	PLOT_ID	EXPRESSION	IIf([TYPE]="Residential","R" & [PLOT_ID],"")	TRUE

I could not figure out how to trigger it. Any help would be appreciated.

Is the layer subtyped by the type? If so you can specify that in the Table Name, such as Parcel|1. Without that, you cannot use different sequences.

Unfortunately it is not subtyped.

So, what if both IDs share the same sequence? For example the sequence is B1, B2, B3, R4, R5, R6. If I split R6, I'll get R7. Is that possible?

You can use one seq and put that value in the field and then use an expression to put the proper prefix

I tried this, but I am not getting expected results.

Table Name	Field Name	Value Method	Value Info	On Create	Rule Weight
Parcel	PLOT_ID	GENERATE_ID	COUNTER	TRUE	1
Parcel	PLOT_ID	EXPRESSION	IIf([TYPE]="Business","B" & [PLOT_ID],IIf([TYPE]="Residential","R" & [PLOT_ID]))	TRUE	0

Syntax is not complete, iif(statement, what to do when true, what to do when false)

IIf(="Business","B" & ,IIf(="Residential","R" & ,))

OK. I tried this with the cut polygon tool but I only get the sequence without the prefix.

Table Name	Field Name	Value Method	Value Info	On Create	Rule Weight
Parcel	PLOT_ID	GENERATE_ID	COUNTER	TRUE	1
Parcel	PLOT_ID	EXPRESSION	IIf([TYPE]="Business","B" & [PLOT_ID],IIf([TYPE]="Residential","R" & [PLOT_ID], [PLOT_ID]))	TRUE	0

Need to turn the log file on and see what it says

The log is very useful. I found my mistake. Accidentally changed the value method. It is working now. Thanks a lot.

This use of the feature class name followed by the subtype number in the Table Name field of the DynamicValue table is an excellent find! I've seen other, less than ideal solutions from ESRI support on how to use different subtypes sequences, but this is the most elegant and easy to implement by far. I just wish it was easier to find in the Attribute Assistant documentation.
