Source document framework for accounting systems

At least one computer-readable storage device comprising instructions that, when executed, cause a system to:

• receive an electronic communication comprising a source document having unknown processing requirements;
• create a new source document type to process the source document and preserve referential integrity in a database by utilizing a set of extension points in computer memory to create a source document header relation with source document header information and a source document line relation with source document line information for a previous source document type, the source document header information and the source document line information being operative to reference at least a portion of the source document for process logic that is specific for use with the previous source document type and defining the new source document type with a non-overlapping foreign key reference to the source document header relation;
• and
• store the source document in the database by using the source document header relation and the source document line relation to reference the source document in that database.

An apparatus, comprising:

• a processor circuit;
• and
• an application arranged for execution by the processor circuit, the application configured to provide services to a database, the application comprising:
• a source document framework component arranged to:
• receive an electronic communication comprising a source having unknown processing requirements,
• create, for an enterprise resource planning (ERP) application, a new source document type from the unknown source document type to process the source document and preserve referential integrity in the database by utilizing a set of extension points in computer memory to create a source document header relation with source document header information and a source document line relation with source document line information for a previous source document type, the source document header information and the source document line information being operative to reference at least a portion of the source document for process logic that is specific for use with the previous source document type and defining the new source document type with a non-overlapping foreign key reference to the source document header relation, and
• store the source document in the database by using the source document header relation and the source document line relation to reference the source document in that database.
