Understanding Building Transaction Master Business Functions

These flowcharts illustrate how transaction master business functions are built.

First, you create the individual business functions using several basic components:

Next, you combine the business functions into a DLL:

You typically use these basic components to create a master business function as described by this table:

Component	Purpose
Begin Document	Called when all header information has been entered. Creates initial header if it has not already been created. Can also include default values, editing, and processing options (POs).
Edit Line	Called when all line information has been entered. Creates cache for detail information if it has not already been created.
Edit Document	Called when ready to commit the transaction. Processes any remaining document edits and verifies that all records are valid to commit.
End Document	Called when you need to commit the transaction. Processes all records in the header and detail cache, performs I/O, and deletes caches.
Clear Cache	Called when you are ready to delete all cache records. Deletes header and detail cache records.
