Hi guys,
I'm using a Dynamic Input with CTE (Common Table Expression), and i'm getting this error:

I noticed there are 3 execution of Dynamic input, the first 2 with same quantity of record and the last one with 1 plus record. First off all i don't know why the tool is executed 3 times, and the last one with one plus record.

Is there something that i can do to avoid this error? Someone can help me?
