• What is the cause and solution for SAP error message SWF_EXP_001183 - Parameter names must be specified as constants ?

  The SAP error message SWF_EXP_001183 indicates that there is an issue with the way parameters are being defined in a workflow or a related function module. Specifically, the error states that parameter names must be specified as constants, which means that the system expects the parameter names to be hard-coded rather than being passed as variables or dynamic values.
  Cause:
  This error typically occurs in the following scenarios:
  
  Dynamic Parameter Names: If you are trying to use a variable or a dynamic expression to define parameter names in a workflow or function call, the system does not allow this and requires that parameter names be specified as constants.
  Incorrect Workflow Configuration: The workflow might be incorrectly configured, leading to the use of non-constant values for parameter names.
  Custom Code Issues: If there is custom code involved in the workflow, it may not be adhering to the expected standards for parameter definitions.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Parameter Definitions: Review the workflow or function module where the error is occurring. Ensure that all parameter names are defined as constants. For example, instead of using a variable to define a parameter name, use a hard-coded string.
  
  
  Modify Workflow Configuration: If you are using a workflow template, check the configuration settings. Make sure that all parameter names are explicitly defined and not derived from variables.
  
  
  Review Custom Code: If there is custom code involved, inspect it for any instances where parameter names are being set dynamically. Change these to use constant values.
  
  
  Testing: After making the necessary changes, test the workflow or function module to ensure that the error is resolved.
  
  
  Consult Documentation: If you are unsure about the correct parameter definitions, refer to the SAP documentation or help resources related to workflows and function modules.
