• What is the cause and solution for SAP error message EG771 - Dev. cat. not possible due to different cert./internal cert. requirements ?

  The SAP error message EG771, which states "Dev. cat. not possible due to different cert./internal cert. requirements," typically occurs in the context of development category assignments in SAP systems, particularly when dealing with transport requests and the associated certification requirements.
  Cause:
  
  Different Certification Requirements: This error usually arises when there is a mismatch between the certification requirements of the development category assigned to the transport request and the certification requirements of the target system or the source system.
  Internal Certification Settings: The internal certification settings in the SAP system may not align with the development category being used. This can happen if the development category is configured to require certain certifications that are not met by the current transport request.
  Transport Layer Issues: If the transport layer settings are not consistent across systems, it can lead to this error. Each system in the landscape may have different settings for development categories and their associated certification requirements.
  
  Solution:
  
  
  Check Development Category Settings: Review the development category settings in the SAP system. Ensure that the development category assigned to the transport request matches the certification requirements of the target system.
  
  You can check this in transaction SE03 (Transport Organizer Tools) or SE01 (Transport Organizer).
  
  
  
  Adjust Certification Requirements: If necessary, adjust the certification requirements in the target system or the development category settings to ensure they are compatible.
  
  This may involve changing the settings in transaction SE03 or SE01 to align the requirements.
  
  
  
  Transport Layer Configuration: Verify the transport layer configuration in transaction STMS (Transport Management System). Ensure that the transport routes and layers are correctly set up and consistent across the systems involved.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to transport management and development categories for specific guidance on resolving certification issues.
  
  
  Contact SAP Support: If the issue persists after checking the above settings, consider reaching out to SAP support for further assistance. They may provide specific notes or patches that address the issue.
  
  
  Related Information:
  
  Transport Management System (TMS): Understanding how TMS works and how development categories are configured can help in troubleshooting this error.
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide additional context.
  System Landscape: Ensure that all systems in the landscape (development, quality assurance, production) have consistent settings regarding development categories and certification requirements.
  
  By following these steps, you should be able to identify and resolve the cause of the EG771 error in your SAP system.
