• What is the cause and solution for SAP error message WZ855 - Rule does not determine any valid agents ?

  SAP Error Message:
  
  WZ855 - Rule does not determine any valid agents
  
  Cause:
  This error occurs in SAP Workflow when a workflow rule (used to determine agents responsible for a workflow step) does not return any valid agents. In other words, the rule evaluation results in an empty agent list, so the system cannot assign the task to any user or organizational unit.
  Common reasons include:  
  
  The rule logic is incorrect or incomplete, leading to no agents being found.  
  The organizational data or master data (e.g., positions, organizational units, users) is missing or not maintained properly.  
  The rule is referencing invalid or non-existent objects or attributes.  
  The workflow container values used by the rule are empty or incorrect.  
  Authorization issues or inactive users/agents.
  
  
  Solution:
  
  
  Check the Rule Logic:  
  
  Go to transaction PFTC (Workflow Builder) or SWO1 (Business Object Builder) and review the rule assigned to the workflow step.  
  Test the rule independently using transaction PFTC or SWI1 to simulate agent determination.  
  Ensure the rule logic correctly references container elements and organizational data.
  
  
  
  Verify Organizational Data:  
  
  Check if the organizational units, positions, or users referenced by the rule exist and are active.  
  Use transaction PPOME or PO13 to verify organizational assignments.  
  Ensure users have valid SAP user IDs and are not locked.
  
  
  
  Check Workflow Container Values:  
  
  Use transaction SWI1 or SWI2_FREQ to inspect the workflow container values at runtime.  
  Make sure the container elements used by the rule are populated correctly.
  
  
  
  Test Agent Determination:  
  
  Use transaction SWI2_DIAG or SWI6 to diagnose workflow errors and agent determination issues.  
  Use the "Agent Determination" test function in the workflow builder.
  
  
  
  Adjust or Redefine the Rule:  
  
  If the rule is too restrictive, modify it to include valid agents.  
  If necessary, create a new rule or use a standard SAP rule that fits your scenario.
  
  
  
  Check Authorizations:  
  
  Ensure that the users or agents have the necessary authorizations to receive workflow tasks.

  Summary:
  WZ855 means the workflow rule failed to find any valid agents to assign a task. To fix it, verify and correct the rule logic, ensure organizational data and container values are correct, and test agent determination thoroughly.
