Subtypes of the SPP Format Project 
When creating an SPP format solution, you need to select from the following two subtypes:
Electronic Document: Used for creation of electronic files from marketing documents.
Electronic Authority Report: Used for summarizing electronic documents created within a specific month.
For either subtype, there is a predefined source file for the default mapping. For the source tables of the Electronic Authority Report subtype, a general naming convention is applied to cover all marketing document tables, as illustrated below:

DOC1 | INV1 |
DOC2 | INV2 |
