1.3.4.5.1 Group

Group is a sub-processor of the Group and Merge processor.

Use the Group sub-processor to select the attributes that you want to group by. Records will be grouped where the values for all selected attributes are exactly the same - in some cases, you might therefore need to resolve any case or punctuation discrepancies using transformation processors before using Group and Merge.

Select the attribute or attributes that you want to group records by, from the input attributes to the Group and Merge processor.

The Allow Nulls checkbox at the bottom of the screen drives whether or not to group together records which are Null in all the selected grouping attributes. Note that if many grouping attributes are used, records may be Null in some but not all attributes in any case; that is, they will be grouped if the values in the non-Null attributes are the same.
