The Edit Transaction function allows two database files to be updated simultaneously. The Edit Transaction function type requires a SPN access path, which is a logical file with two formats.
In order for a SPN access path to be built over two files, the two files must be connected by a file-to-file relation; for example, an Owned by relation. The Edit Transaction function provides a display consisting of a subfile control format for the owning file and a subfile record format for the owned file.
You will set up an Edit Transaction function for the RACE and RACE ENTRY files. This provides the facility to enter both the race details and the race entry details for a given race on the same interactive panel.
