• What is the cause and solution for SAP error message R1420 - No change document objects have been assigned to the application tables ?

  The SAP error message R1420, "No change document objects have been assigned to the application tables," typically occurs when you are trying to use change document functionality in SAP, but the relevant application tables do not have change document objects assigned to them. Change documents are used in SAP to track changes made to certain data records, and they require specific configuration to function properly.
  Cause:
  
  Missing Change Document Objects: The application tables you are working with do not have change document objects defined. This means that SAP does not know which fields to track for changes.
  Incorrect Configuration: The change document functionality may not have been properly configured for the specific application or table you are trying to use.
  Authorization Issues: In some cases, the user may not have the necessary authorizations to access change documents.
  
  Solution:
  
  
  Check Change Document Configuration:
  
  Go to transaction code SCDO (Change Document Objects).
  Verify if the relevant change document object is defined for the application table you are working with.
  If it is not defined, you may need to create a new change document object for that table.
  
  
  
  Assign Change Document Objects:
  
  If the change document object exists but is not assigned to the table, you can assign it using transaction code SCDO.
  Ensure that the fields you want to track are included in the change document object.
  
  
  
  Review Table Settings:
  
  Check the table settings in transaction code SE11 (Data Dictionary) to ensure that the table is set up to use change documents.
  Look for the "Change Document" checkbox in the table definition.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to view change documents. This can be checked in transaction code SU53 or by consulting with your security team.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific instructions on how to set up change documents for the application you are working with.
  
  
  
  Related Information:
  
  Change Document Objects: These are defined in the SAP system to specify which tables and fields should be monitored for changes.
  Transaction Codes:
