• What is the cause and solution for SAP error message WTYMP004 - Job ID not allowed: use only letters A-Z and numbers 0-9 ?

  SAP Error Message:
  
  WTYMP004 – Job ID not allowed: use only letters A-Z and numbers 0-9
  
  Cause:
  This error occurs when a job ID (or job name) contains invalid characters. SAP requires that job IDs consist only of uppercase letters (A-Z) and digits (0-9). If the job ID includes any other characters such as lowercase letters, special characters, spaces, or symbols, the system will raise this error.
  
  Explanation:
  
  SAP job IDs are identifiers used in background job scheduling.
  The system enforces a strict naming convention to avoid issues in job processing and identification.
  Invalid characters can cause problems in job management, logging, or interfacing with other system components.
  
  
  Solution:
  
  Check the job ID/name you are trying to use.
  Modify the job ID so that it contains only uppercase letters (A-Z) and digits (0-9).
  Avoid spaces, special characters (e.g., -, _, @, #), and lowercase letters.
  For example:
  
  Valid: JOB123, MYJOB01
  Invalid: job123, Job_01, JOB-01, JOB 01
  
  
  
  
  How to fix in practice:
  
  When creating or scheduling a job via transaction codes like SM36 (Define Background Job), ensure the job name follows the naming rules.
  If the job name is generated programmatically (e.g., via ABAP code), add validation or conversion logic to enforce uppercase letters and digits only.
  Example ABAP snippet to convert and validate job name:
  
  DATA lv_jobname TYPE tbtcjob-jobname.
  lv_jobname = 'job_01'. " Example input
  
  " Convert to uppercase
  lv_jobname = to_upper( lv_jobname ).
  
  " Remove invalid characters (example: keep only A-Z and 0-9)
  REPLACE ALL OCCURRENCES OF REGEX '[^A-Z0-9]' IN lv_jobname WITH ''.
  
  " Now lv_jobname is valid for job creation
  
  Related Information:
  
  Transaction SM36 – Define Background Job
  Transaction SM37 – Job Monitoring
  SAP Note or documentation on job naming conventions
  Background job naming restrictions are important for system consistency and integration with external schedulers or monitoring tools.
  If you are using third-party tools or custom programs to create jobs, ensure they comply with SAP's naming rules.
