What causes this issue?

The specified table is an append structure. These are provided to allow
customers to extend standard tables. All fields that the customer
wishes to add to a standard table are collected together in an append
structure. When you activate the table, all appends to this table are
located and the fields contained in these appends are added to the
table.
Consequently, an append structure must be assigned to a single table.
This condition is not fulfilled in this case.

• What is the cause and solution for SAP error message DT108 - Table & is of type append, but is not assigned to a table ?

  The SAP error message DT108 indicates that there is an issue with a database table that is defined as an "append" table but is not properly assigned to a base table. This can occur during the development of database tables in the ABAP Dictionary (SE11) when the append structure is not linked correctly to its corresponding base table.
  Cause:
  
  Incorrect Assignment: The append table is not assigned to any base table. This can happen if the append structure was created without linking it to a specific table.
  Table Deletion: The base table to which the append structure was originally assigned may have been deleted or renamed.
  Transport Issues: If the append structure was transported from one system to another, there may have been issues during the transport that caused the assignment to be lost.
  
  Solution:
  
  
  Check Assignment: Go to transaction SE11 and check the definition of the append structure. Ensure that it is correctly assigned to a base table.
  
  Open the append structure and verify the "Table" field to ensure it points to the correct base table.
  
  
  
  Reassign the Append Structure: If the append structure is not assigned, you can reassign it to the appropriate base table.
  
  In SE11, select the append structure, and in the "Table" field, enter the name of the base table to which it should be appended.
  
  
  
  Check for Deletions: If the base table has been deleted, you may need to recreate the base table or remove the append structure if it is no longer needed.
  
  
  Transport Check: If the issue arose after a transport, check the transport logs for any errors related to the append structure or base table. You may need to re-transport the objects.
  
  
  Activate the Objects: After making any changes, ensure that you activate both the base table and the append structure to apply the changes.
  
  
  Related Information:
