loop step with a decision table - confirmation

Hi Guys,

I'm trying to create an expression for sending a table (2 fields: source, target) like line type - source_line

and I want to loop via a decision table to get the target field - can you please confirm my understanding of the flow:

1. processing mode (Perform Action - as I only want to change the target field in the source/input table) ?

2. rule:

change "source_line" after processing - "decision table with two fields - (source and target)"

is that all ?

Thank you for confirmation,

Regards,

Michal Krawczyk
