Electronic reporting (GER) allows to manage a model configuration that can be used as a data source for generation of electronic documents. Each data model can contain multiple root elements. Each root element specifies a unique data flow for using model that may require when a model is used in different business processes for generation of specific electronic documents. To specify a data flow for a single root element of a data model, a single model mapping must be configured.

When you create a new GER format for generation of electronic documents, you must select a desire data model along with its root element to explicitly define the desired data source. Currently, for the selected data model you can select the only root element to which a model mapping has been already created. You can’t design your report with using a data model’s root element which has no model mapping yet.

To work around this issue, you may create a new model mapping for the desired root element to pass a new format creation step. Then, this model mapping can be deleted since it is not needed at the design time and will be required at run-time only when you run your format for generation of electronic documents.
