• What is the cause and solution for SAP error message WI412 - Select one object ?

  SAP Error Message:
  
  WI412 - Select one object
  
  Cause:
  The error message WI412 - Select one object typically occurs in SAP Workflow when a user or a process tries to perform an action that requires exactly one object to be selected, but either no object or multiple objects have been selected.
  In other words, the workflow step or transaction expects a single object instance (such as a business object, task, or container element), but the input provided is either empty or contains more than one object.
  
  When does it occur?
  
  When triggering a workflow step that requires a single object reference.
  When a user tries to process a task or event without selecting the required object.
  During workflow container binding or method calls where the parameter expects exactly one object.
  In workflow inbox or task processing screens where the system expects one selected item.
  
  
  Solution:
  
  
  Select exactly one object:
  
  Ensure that you select exactly one object before proceeding. For example, if you are in a workflow inbox or task list, select a single task or object.
  
  
  Check workflow container bindings:
  
  If you are developing or debugging a workflow, verify that the container element or method parameter is correctly bound to a single object instance, not a table or multiple objects.
  
  
  Review the workflow step configuration:
  
  Make sure the step or method that triggers this error is designed to handle only one object. If multiple objects are expected, adjust the logic accordingly.
  
  
  Check user input or selection screens:
  
  If the error occurs during user interaction, guide the user to select one item only.
  
  
  Debug the workflow:
  
  Use transaction SWI1 (Workflow Log) or SWDD (Workflow Builder) to analyze the workflow steps and container values to identify where multiple or no objects are passed.

  Common scenarios:
  
  Workflow step expecting a single object but receiving a table or multiple entries.
  User interface screens where multiple selections are possible but only one is allowed.
  
  
  
  
  Summary:
  The WI412 - Select one object error means that the system expected exactly one object to be selected or passed, but this condition was not met. The solution is to ensure that exactly one object is selected or passed to the workflow step or method.
