• What is the cause and solution for SAP error message WEBI_CHECKS021 - Service Definition &1: Parameter &2 has unknown Type &3 ?

  The SAP error message:
  WEBI_CHECKS021 Service Definition &1: Parameter &2 has unknown Type &3
  Cause:
  This error occurs in SAP BusinessObjects Web Intelligence (WebI) when a service definition contains a parameter whose data type is not recognized or supported by the system. Essentially, the WebI processing engine encounters a parameter type in the service definition that it cannot map to a known or valid data type.
  Common scenarios causing this error include:
  
  Custom or incorrectly defined service definitions with parameters having unsupported or misspelled data types.
  Mismatches between the service definition and the WebI report/query expecting certain parameter types.
  Upgrades or patches that introduce stricter type checking or changes in supported parameter types.
  Corrupted or inconsistent metadata in the repository or service definitions.
  
  Solution:
  
  
  Check the Service Definition:
  
  Identify the service definition mentioned in the error message (&1).
  Review the parameters defined in this service definition, especially the parameter named &2.
  Verify the data type of this parameter (&3).
  
  
  
  Correct the Parameter Type:
  
  Ensure the parameter type is one of the supported types in WebI service definitions, such as:
  
  String
  Integer
  Boolean
  Date
  Double/Decimal
  
  
  If the type is custom or unknown, change it to a supported type.
  
  
  
  Update or Recreate the Service Definition:
  
  If the service definition is corrupted or outdated, consider recreating it or updating it via the Central Management Console (CMC) or the relevant administration tool.
  Re-import or re-publish the service definition if it was imported from an external source.
  
  
  
  Check for Patch or Version Issues:
  
  Verify if the SAP BusinessObjects version you are using supports the parameter types defined.
  Apply any relevant patches or updates that fix known issues related to service definitions and parameter types.
  
  
  
  Clear Cache and Restart Services:
  
  Sometimes, cached metadata can cause inconsistencies.
  Clear the WebI cache and restart the SAP BusinessObjects services to ensure changes take effect.
  
  
  
  Consult SAP Notes and Documentation:
  
  Search SAP Support Portal for notes related to WEBI_CHECKS021.
  There might be specific fixes or recommendations for your SAP BusinessObjects version.
