Changing Rules Sample

Download sample

The workflow in this sample implements a simple PO approval condition: if the supplied PO amount is less than or equal to $10,000, the PO requires manager approval; otherwise, it requires VP approval. The workflow runs this logic two times via a simple WhileActivity loop. The application starts the workflow with a request value of $14,000. Therefore, for the first iteration of the loop, VP approval is required.

For the second iteration of the loop, the business logic is changed, and the manager approval threshold is increased to $15,000. Therefore, on the second execution, only manager approval is required.

For the sake of simplicity, this sample uses a DelayActivity activity to block the workflow. For a more robust application, a SuspendActivity activity or a HandleExternalEventActivity activity should be used.

When you build and run the sample, your output will appear similar to the following:
