• What is the cause and solution for SAP error message DT879 - Table & is not active in ABAP Dictionary ?

  The SAP error message DT879, which states "Table & is not active in ABAP Dictionary," typically occurs when you are trying to access a database table that has not been activated in the ABAP Dictionary. This can happen for various reasons, such as changes made to the table structure that have not been activated, or the table being in a state that prevents it from being used.
  Cause:
  
  Table Not Activated: The most common cause is that the table has been modified (e.g., fields added, deleted, or changed) and has not been activated after these changes.
  Transport Issues: If the table was transported from one system to another, it might not have been activated in the target system.
  Development Environment: If you are working in a development environment, the table might be in a state of modification and not yet activated.
