J5320 - Details

• The SAP error message J5320 indicates that the namespace for generating programs is full. This typically occurs when the system has reached its limit for the number of objects (like programs, function modules, classes, etc.) that can be created in a particular namespace. 
  
  Cause:
  
  Namespace Limit Reached: Each SAP system has a limit on the number of objects that can be created in a namespace. If this limit is reached, you will encounter this error.
  Development Objects: The error may arise in a development environment where many objects are being created, and the namespace is not properly managed.
  Transport Requests: If there are many transport requests pending or if objects are not being properly deleted or archived, it can lead to this issue.
  
  
  Solution:
  
  Check Namespace Usage: Use transaction code SE03 (Transport Organizer Tools) to check the usage of the namespace and see how many objects are currently in use.
  Delete Unused Objects: Identify and delete
