Different Types of Assigns
The assign element is a BPML construct you can use to perform simple assignment operations within a service call. You can also use assign statements outside of any operation, input, or output tags.
Performing a simple assignment operation within a service call is illustrated in the first example (see Input and Output Examples). Sometimes called top-level assignment, this method enables you to manipulate the process data directly, outside the service call in a process rather than within the service step.
Within Sterling B2B Integrator, the Assign service configuration is available for this purpose, and in the GPM, it is represented as the Assign activity, available as an icon from the BPML stencil. This topic discusses the assign element, not the service or activity, but it is important to note that top-level assignments follow the same conventions outlined here.
