CA Gen provides the NEXTTRAN (next transaction) special attribute as the means to invoke non-CA Gen transactions from a CA Gen-generated transaction. The NEXTTRAN attribute is specified within a Dialog Flow Diagram.
Note: For more information about the Dialog Flow Diagram and NEXTTRAN, see Design Guide.
You can use the NEXTTRAN attribute to implement the following types of flows:
When transferring to non-CA Gen-generated transactions, the NEXTTRAN attribute can specify the transaction code to be invoked by the Dialog Manager when the current transaction terminates. You can place the NEXTTRAN attribute on a screen and can have the user enter the desired transaction code in the field. Alternately, you can set the NEXTTRAN attribute using the SET command. In either case, the transaction code must conform to the requirements of the teleprocessing monitor and the receiving transaction.
The NEXTTRAN field must be formatted correctly for the receiving transaction. The transaction code and any unformatted input data must be valid to the receiving transaction.
The use of external action blocks is another method by which you can access existing subroutines and databases.
