SV355 - Details

• The SAP error message SV355, which states "The dynpro number is in the reserved customer range," typically occurs when there is an attempt to use a screen number (dynpro) that falls within the range reserved for customer development. In SAP, certain ranges of screen numbers are reserved for standard SAP use, while others are designated for customer-specific development.
  
  Cause:
  
  Dynpro Number Conflict: The dynpro number you are trying to use is already reserved for customer use or is conflicting with an existing screen in the system.
  Development Environment: If you are working in a development environment, it is possible that the screen number you are trying to create or modify is already in use or has been reserved by another developer.
  Incorrect Configuration: Sometimes, the configuration settings may not be correctly set, leading to the system interpreting the dynpro number as reserved.
  
  
  Solution:
  
  Check Dynpro Number: Verify the dynpro number you are trying to use. Ensure
