• What is the cause and solution for SAP error message DO787 - Naming conflict: &1 is deleted as &2 and activated as &3 ?

  The SAP error message DO787 indicates a naming conflict in the system. This typically occurs when an object (like a program, function module, or class) is deleted or renamed, and there is an attempt to activate another object with the same name. The message format is as follows:
  
  &1: The name of the object that was deleted.
  &2: The name of the object that was activated.
  &3: The new name of the object that is being activated.
  
  Cause:
  The error arises due to the following reasons:
  
  Naming Conflict: An object with the same name already exists in the system, which can happen if an object was deleted or renamed, and another object is being activated with the same name.
  Transport Issues: If you are working with transport requests, there might be inconsistencies between the development and production environments.
  Development Environment Changes: Changes made in the development environment that have not been properly transported or activated in the target environment.
  
  Solution:
  To resolve the DO787 error, you can follow these steps:
  
  
  Check Object Status: Verify the status of the objects involved. Use transaction codes like SE80 (Object Navigator) or SE11 (Data Dictionary) to check if the object is indeed deleted or if there are any inconsistencies.
  
  
  Rename the Object: If you are trying to activate an object with a name that is already in use, consider renaming the new object to avoid the conflict.
  
  
  Transport Consistency: Ensure that all relevant transport requests have been properly imported into the target system. If there are pending transports, complete them.
  
  
  Delete or Adjust Conflicting Objects: If the object that is causing the conflict is no longer needed, you may delete it. However, ensure that this does not affect other dependencies in the system.
  
  
  Check for Dependencies: Sometimes, other objects may depend on the object that is being activated. Check for any dependencies and resolve them accordingly.
  
  
  Re-activate the Object: After resolving the conflict, try to activate the object again.
  
  
  Related Information:
