Inbound processing analyzes the context of a form. During the conversion of data from the XML format to the ABAP format, the context is taken into account. In the properties of the context node (under Data or Structure in the Field attribute or under Loop in the Table attribute) a reference is defined to the interface, the parameters of which are to be evaluated (see also Data Extraction from Interactive PDF-Based Print Forms). During the conversion of the XML data of the form to ABAP data of the interface, only this reference is taken into account.
