  Error Message
  WFF_FORM_SERVER803: Select one object only
  
  Cause
  This error occurs in SAP Workflow when a user or a program tries to select or process multiple objects at once in a context where only a single object is allowed or expected.
  Common scenarios include:
  
  A workflow step or task is designed to handle only one object instance, but multiple objects are selected or passed.
  The workflow container or the workflow task expects a single object reference, but the input contains multiple objects.
  User interaction in a workflow form or selection screen where multiple selections are made but only one is permitted.
  
  
  Explanation
  SAP Workflow engine enforces strict rules on object selection in certain steps or tasks. When a workflow step is configured to work with a single object (for example, a single purchase order, a single document, or a single master data record), selecting multiple objects violates this rule and triggers the error.
  
  Solution
  
  
  Check the Workflow Step Configuration:
  
  Verify the workflow step or task that triggers this error.
  Ensure that the step is designed to handle only one object.
  If multiple objects need to be processed, consider redesigning the workflow to loop over objects or handle them one by one.
  
  
  
  Check the Input to the Workflow Step:
  
  Review the container elements or input parameters.
  Make sure only one object instance is passed to the step.
  If the input is coming from a selection screen or user input, restrict the selection to a single object.
  
  
  
  Adjust User Selection:
  
  If the error occurs during user interaction (e.g., in a workflow form), instruct users to select only one object.
  Modify the UI element (e.g., radio buttons instead of checkboxes) to enforce single selection.
  
  
  
  Debugging:
  
  Use transaction SWI1 or SWI2_DIAG to analyze the workflow log and identify the exact step causing the error.
  Check the container values and the object references passed.
  Use debugging tools to trace the workflow execution and verify the object selection.
  
  
  
  Enhance Workflow Logic (if needed):
  
  If business requirements demand processing multiple objects, implement a loop or multiple workflow instances.
  Alternatively, modify the workflow to accept a table of objects and process them accordingly.
