Semantic Grouping

If a semantic grouping is used, data records with the same values in the selected fields form a logical key and are processed together in one package.

This setting must be considered in combination with the settings for semantic groups in DTP:

If handling data records with errors is activated, only the sources fields of key fields can be selected in DTP. The actual grouping uses the intersection of these selected key fields and the fields selected from the transformation for semantic grouping.

If handling data records with errors is switched off, all the sources fields that were also selected in the transformation can be selected in DTP. The selection of the semantic group is formed from this intersection.

If handling data records with errors is switched off, and no source fields have been selected in the transformation for the semantic grouping, all the source fields can be selected in DTP. This function has been retained for compatibility reasons, due to it not being possible to display source fields for the semantic grouping in the transformation. We recommend selecting the fields in the transformation however.
