• What is the cause and solution for SAP error message RJ036 - Do not use a projection view in a pool/cluster table ?

  The SAP error message RJ036, which states "Do not use a projection view in a pool/cluster table," typically occurs when there is an attempt to create or use a projection view on a pool or cluster table in the SAP system. Pool and cluster tables are special types of database tables in SAP that are designed to store data in a way that optimizes storage and performance, particularly for certain types of applications.
  Cause:
  The error arises because projection views are not supported for pool or cluster tables. Projection views are designed to provide a simplified view of a database table by selecting specific fields, but they are not compatible with the structure and storage mechanisms of pool and cluster tables. These tables are managed differently in the database, and the use of projection views can lead to inconsistencies or performance issues.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Avoid Using Projection Views: Instead of using a projection view, directly access the pool or cluster table using a standard database view or a different type of view that is compatible with these table types.
  
  
  Use Transparent Tables: If you need to create a view that simplifies access to certain fields, consider using transparent tables instead of pool or cluster tables. Transparent tables are standard database tables that can be used with projection views.
  
  
  Check Data Model: Review the data model to ensure that the use of pool or cluster tables is necessary. If possible, redesign the data model to use transparent tables where projection views are needed.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on the limitations and best practices regarding the use of pool and cluster tables and views.
  
  
  Seek Expert Advice: If you are unsure about the best approach, consider consulting with an SAP expert or a developer who has experience with database design in SAP.
  
  
  Related Information:
  
  Pool Tables: These are logical tables that group multiple tables together to save space. They are not directly accessible in the same way as transparent tables.
  Cluster Tables: These tables store data from multiple tables in a single physical table to optimize storage. They are also not directly accessible like transparent tables.
  Transparent Tables: These are standard database tables that have a one-to-one relationship with the database and can be used with all types of views, including projection views.
  
  By following these guidelines, you should be able to resolve the RJ036 error and design your data model appropriately for your SAP applications.
