This field is used to define grouping criteria by providing a list of expressions (or fields) separated by semicolons. This is useful to group detail lines and thus only trigger one Workflow upon each break on the values defined by these expressions.
This is possible in two cases :
- When a Workflow event uses a data template displaying links (1,N), and the Workflow is of a line type (it runs through all the lines in the selected line table), lines can be grouped together.
- When a Workflow event is of a Manual type, (all read lines can be grouped together in the same manner).
