• What is the cause and solution for SAP error message HRPADUN_GEN404 - No unused Index-Number available. ?

  The SAP error message HRPADUN_GEN404: No unused Index-Number available typically occurs in the context of HR (Human Resources) data processing, particularly when dealing with infotypes or records that require unique index numbers for storage or processing.
  Cause:
  The error indicates that the system has run out of available index numbers for a specific infotype or data structure. Each infotype in SAP HR is assigned a unique index number, and when all available numbers are used up, the system cannot assign a new one, leading to this error.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check Existing Infotypes: Review the infotypes that are currently in use for the employee or object in question. You can do this by using transaction codes like PA20 (Display HR Master Data) or PA30 (Maintain HR Master Data).
  
  
  Delete Unused Records: If there are infotype records that are no longer needed, consider deleting them to free up index numbers. Be cautious with this step, as it may affect historical data.
  
  
  Increase Index Number Range: If the infotype is designed to handle a limited number of records, you may need to adjust the configuration to allow for a larger range of index numbers. This typically requires access to the SAP configuration settings and may involve working with your SAP Basis or HR team.
  
  
  Check for Custom Developments: If there are custom programs or enhancements that interact with HR data, ensure they are not inadvertently consuming index numbers without releasing them.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address this issue. There may be specific recommendations or fixes provided by SAP.
  
  
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP Support for assistance. They can provide guidance based on the specific configuration and version of your SAP system.
