Increment ID with local Variable?

Hi Team,

I am facing issue while incrementing label "ID" value using local variable.

Can anybody help me how to write code for it?

Thank you!

You're incrementing a local variable that you're not initialising to an explicit value but will usually be zero. Use a global variable, eg. myID, instead of the local one. The you can use it in the label assigment directly with the increment operator++:

Hi @Jason Lightfoot,

Thank you for your answer!

But I am looking for approach using local variable only. The reason is I have to use hundreds of variable in my model. I don't know if defining global variable every time is effective approach?

What would your suggest in such case? Will you still recommend to use global variable?

Thank you!

Then put a label on an object and increment that. The question is how many distinct incrementing counters do you want and how are they grouped/partitioned?

combining Token.ID and table rows is not an recommended approach, because there are other processes under the hood which can create tokens,too. You should think about to set a process flow label for such a task, where you link an ID value to numbers of rows in tables. Or you you evaluate your table directly to get numbers of rows by property numRows.
