• What is the cause and solution for SAP error message WS355 - Enter a run name ?

  SAP Error Message:
  
  WS355 - Enter a run name
  
  Cause:
  The error message WS355 "Enter a run name" occurs when you are trying to execute a background job or a report that requires a run name (also called a variant name or job name) but you have not provided one. The system expects a run name to identify the specific execution variant or job instance, and if it is missing, this error is triggered.
  This typically happens in scenarios such as:  
  
  Scheduling a background job without specifying a run name.  
  Executing a report or program that requires a run name to differentiate between different execution variants.  
  Using transaction codes or custom programs that mandate a run name parameter.
  
  
  Solution:
  To resolve the WS355 error, you need to enter a valid run name in the input field where the system expects it. Here are the steps:
  
  
  Identify the field for the run name:
  
  When scheduling a job or running a report, look for the input field labeled "Run name," "Job name," or similar.
  
  
  Enter a meaningful run name:  
  
  The run name should be unique or descriptive enough to identify the job or report execution.  
  It can be alphanumeric and follow your organization's naming conventions.
  
  
  
  Save or execute the job/report:
  
  After entering the run name, proceed with saving or executing the job.
  
  
  If using variants:  
  
  You may need to create or select an existing variant that includes the run name.  
  Use transaction SE38 or SA38 to create/select variants for reports.
  
  
  
  Check authorization:  
  
  Ensure you have the necessary authorization to create or schedule jobs with run names.
  
  
  
  
  Additional Information:
  
  
  Background Jobs:
  
  In SAP, background jobs are scheduled with a job name and optionally a run name to distinguish different executions or variants. The run name helps in managing and identifying jobs in job monitoring transactions like SM37.
  
  
  Variants:
  
  Variants store input values for reports/programs. The run name can be linked to a variant to reuse input parameters.
  
  
  Transaction Codes:  
  
  SM36 - Define background job (where you specify job name and steps).  
  SM37 - Monitor background jobs.  
  SE38 / SA38 - Execute reports and manage variants.
  
  
  
  Custom Programs:
  
  If this error appears in a custom program, check the program logic to ensure the run name parameter is correctly handled and mandatory fields are validated.
