I have an Id field in a table & need to add the max id + 1 to a new set of features with the same field name

Yes, StatisticsCalculator + ExpressionEvaluator will address this

A possible way is:

 

get the maximum value of Id in the first table with a StatisticsCalculator,

 

merge the "max Id" to the subset features unconditionally with a FeatureMerger,

 

then add Id starting with (max Id + 1) to the features using a Counter.

 

e.g.

 

 

To merge "Id._max" to the subset features unconditionally, set an identical constant value (e.g. 1) to the Join On parameter for both Requestor and Supplier.

 

 

If the first table was stored in a database, you can also use the SQLCreator or SQLExecutor to get the maximum Id value efficiently with a SQL statement like this.

 

select max(Id) as maxId from first_table;
