Before: initial message map behavior

Review this topic for a description of the initial message map file for the scenario, its transformations and what changes you make when you implement the scenario solution.

The initial map file for the scenario is called MembersMFPFlow_Mapping.msgmap. The message map takes a generic input message with details of a person and transforms it to a message required by a member database system that adds a member record for the person.

Tip: This scenario was developed by using a sample of an initial message map configuration. If you want to try out the scenario, you can either use your own integration solutions, or set up a copy of the sample configuration as described in Creating the scenario message map configuration.

There are aspects to consider before you convert your maps to ensure that your broker (or integration node in IBM® Integration Bus) operates as intended. For more information, see Converting a legacy message map that includes ESQL mapping functions. Although this scenario includes the necessary information from that topic, if you are using your own maps you might want to review that topic to understand what changes you might encounter.

The following image shows how the MembersMFPFlow_Mapping.msgmap map file looks before conversion:

Screen capture of the initial message map configuration and some of the transformation types.

The image shows some, but not all of the transformations that are used in the message map. The message map includes the following significant transformation logic:

One of the transformations for MEMBER_COMMENT1 uses an ESQL function, esql:trim-both, that is not supported for graphical data maps. The list of non-supported ESQL functions is listed in Converting a legacy message map that includes ESQL mapping functions.

See the following image for the construction of the expression using esql:trim-both:

Review the next topic to see what changes are made to transformations when they are converted in a graphical data map. After: the converted graphical data map.
