append structure to the same table. Since both append structures would
then contain the same fields, this would mean that the appending table
would contain these fields twice.

If you want to include the fields of an append structure in another
table, you can do this with the function ->Extras->Copy fields
in the maintenance transaction for the target table.

• What is the cause and solution for SAP error message D0850 - You may not copy append structure & ?

  The SAP error message D0850, which states "You may not copy append structure &," typically occurs when you attempt to copy an append structure that is not allowed to be copied due to certain restrictions in the SAP system. Append structures are used to add fields to existing database tables, and there are specific rules governing their use.
  Cause:
  
  System Restrictions: The append structure you are trying to copy may have restrictions set by the system. For example, it might be a standard append structure provided by SAP, which cannot be copied or modified.
  Authorization Issues: You may not have the necessary authorizations to copy the append structure.
  Technical Settings: The append structure may be linked to specific technical settings that prevent copying.
  Inconsistent State: The append structure might be in a state that does not allow copying, such as being locked or in a transport request.
  
  Solution:
  
  Check the Append Structure: Verify if the append structure is a standard one provided by SAP. If it is, you cannot copy it. Instead, you may need to create a new custom append structure.
  Create a New Append Structure: If you need to add fields, consider creating a new append structure instead of copying an existing one.
  Review Authorizations: Ensure that you have the necessary authorizations to perform the operation. You may need to consult with your SAP security team.
  Check for Locks: Make sure that the append structure is not locked or in a transport request that is currently being processed.
  Consult Documentation: Refer to SAP documentation or notes related to the specific append structure for any additional restrictions or guidelines.
