• What is the cause and solution for SAP error message JP021 - Projects with this Project coding ID exist in the production system ?

  The SAP error message JP021 indicates that there are existing projects in the production system that are associated with the specified project coding ID. This typically occurs when you attempt to create or modify a project in SAP Project System (PS) and the system detects that the project coding ID you are trying to use is already in use by another project.
  Cause:
  
  Existing Projects: The project coding ID you are trying to use is already assigned to one or more projects in the production environment.
