I am trying to perform a GroupBy function using two constant variables, and a third set of variables groups in succession via the TableRow to Loop Start method. However, I get the following error:
Execute failed: Input table's structure differs from reference (first iteration) table: Column 2 [name=Tagged:X,type=StringCell] vs. [name=Tagged:Y,type=StringCell]
...where Tagged:X and Tagged:Y are the first two values of the flow variables.
