You can reuse multiple times a user-defined element that you have modeled in the input message assembly or in the output message assembly. All instances of the reused user-defined element must be of the same type.
You can reuse user-defined elements in the same message map or in a different message map.
To reuse a user-defined element in multiple maps, you can define the user-defined element in a submap. Alternatively, you can copy and paste the user-defined element between maps. When you copy a user-defined element, you must maintain in multiple places any changes you make to the user-defined element.
Complete the following steps to copy into the output message assembly a user-defined element that is defined in the input message assembly:
Edit the message map, and define transformations between the input message assembly and the output message assembly. For more information, see Mapping input to output elements manually.
