Hi Gurus

I have set a local variable process to perform a control check on my partita iva (italian vat number). I don't understand why there is incompatibility error and why i cannot use if statement.

Please see attaches

thanks for your help

You cannot use "if" there because what you write as an expression appears on the right side of the variable affectation. Let's say if you variable is called v1, the generated code will be "var1 = your expression" (have a look at generated code).
So the solution is to replace the "if" by a ternary expression such as "row1.field1 > 1 ? 1: 0".
