# Example of IMS BMP Trigger

This example illustrates how a trigger process delivers data from an IMS Batch Message Program (BMP) or a 3270 device to a TIBCO messaging application through Substation ES.

The JCL is supplied with the installation of Substation ES. The IMS BMP Trigger example uses this JCL to invoke the IMS transaction.

The IMS BMP initiates the request by inserting the output data to the IMS message queue (TPipe). The TPipe delivers the IMS outbound events to Substation ES, which gets the trigger based on the defined search criteria for this trigger process. Substation ES Transformer then processes the data conversions according to the selected conversion rule in the trigger recipe.

After the data has been converted, Substation ES publishes the output message to the IVP Generic Listener.

For more information about the process flow, see the "Messages Flow" section of the TIBCO Substation ES Concepts manual.
