• What is the cause and solution for SAP error message WO806 - Parameter type & is not defined (only S or P) ?

  The SAP error message:
  WO806 Parameter type & is not defined (only S or P)
  typically occurs in the context of SAP Workflow when defining or using workflow container elements or parameters.
  
  Cause
  
  The error indicates that a parameter type used in a workflow container element or in a workflow step is not correctly defined.
  Specifically, the parameter type must be either:
  
  S (Structure)
  P (Table Parameter)
  
  
  If the parameter type is something else or missing, SAP throws this error.
  This usually happens when:
  
  You define a container element or parameter with an invalid or unsupported type.
  There is a mismatch or typo in the parameter type.
  The workflow container element or method parameter is incorrectly configured.
  
  
  
  
  Explanation of Parameter Types
  
  S (Structure): The parameter is a single structure or data object.
  P (Table Parameter): The parameter is a table (internal table).
  
  SAP Workflow only supports these two parameter types for container elements and method parameters.
  
  Solution
  
  
  Check the Workflow Container Elements:
  
  Go to the workflow builder (transaction SWDD).
  Open the workflow and check the container elements.
  Verify that all container elements have their parameter type set to either S or P.
  Correct any container element with an invalid or missing parameter type.
  
  
  
  Check Method Parameters in Workflow Steps:
  
  If the error occurs during method call steps, check the method interface.
  Ensure that the method parameters used in the workflow step are of type structure or table.
  Adjust the method or the workflow step parameters accordingly.
  
  
  
  Check Custom Code or Enhancements:
  
  If you have custom workflows or enhancements, verify that the container elements and parameters are correctly defined.
  Fix any incorrect parameter type definitions.
  
  
  
  Transport and System Consistency:
  
  Sometimes, inconsistencies between development and production systems can cause this.
  Ensure that the workflow and related objects are properly transported and consistent.
