Debugging Workflow in SAP: A Step-by-Step Guide

How To Debug Workflow In Sap

Finding why the particular work item routed to agent ‘X’ and not to agent ‘Y’ is one of the most common issues which you come across when you are working on SAP Workflow.


Imagine a scenario where a purchaser generates a Purchase Order with the number 123456789. A workflow associated with this specific purchase order is activated to seek approval or rejection, and it is directed to various agents or approvers based on customized business code logic or standard procedures.

Let’s see how the workflow is triggered for this Purchase Order and whom it is routed to.

Navigate to transaction ME23N and enter the Purchase order number. Access the Workflow overview section.

Next, select the workflow Log option. This will direct you to the page displaying comprehensive information about the work item or workflow.

After selecting the log button, you will be directed to the workflow log page. Here, you can access all the technical information related to the work item. By clicking on the Agent information button, you can find out which individual is currently assigned as the agent for this specific work item or workflow. This indicates whose inbox contains this particular work item.

Debugging Workflow in SAP: Unraveling the Routing of Work Items

In order to solve this puzzle, it is necessary to debug the work item if the determination of the agent is carried out through a workflow rule.

  • Click on the ” List with technical details ” button

When you select the technical settings button, it will display all the technical information associated with this particular work item at the lower part of the system.

  • Now as you can see the workitem “987456321” is coming under the task “TSXXXX”. Click on the task and it will route you to the Task id. Go to the “Default rules” tab. Under the rule, a rule number ” 1478529 ” is set. So friends, this is the rule that is responsible for fetching the agents/approvers.
  • Now to find out the standard or custom logic behind this function module ” ME_REL_GET_RESPONSIBLE “, double click on the function module and put a external breakpoints in the program.

Please ensure to utilize the External breakpoints for debugging the Agent Determination Rule.

Return to the agent determination Rule and select the Simulation option. This will open a screen called Simulation for Rule Resolution. Fill in the required information using F4 and run it. In our case, we entered the Purchase order number and Release code as examples.

When you press the F8 key or exit the debugger, the simulation will display a list of agents.

I trust that you have gained an understanding of the process for debugging the Agent Determination Work Item in SAP Workflow. 🙂
