• What is the cause and solution for SAP error message AD155 - Table & is new (action not allowed) ?

  The SAP error message AD155 ("Table & is new (action not allowed)") typically occurs when you are trying to perform an action on a table that has not yet been activated or is in a state that does not allow the action to be performed. This error is often encountered in the context of ABAP Dictionary operations, such as when trying to activate or modify a table that has not been fully defined or activated in the system.
  Cause:
  
  Table Not Activated: The most common cause is that the table you are trying to work with has not been activated in the ABAP Dictionary.
  Incomplete Definition: The table may have an incomplete definition, meaning that required fields or properties have not been set.
  Transport Issues: If the table was recently transported from another system, it may not have been activated in the target system.
  Development Environment: If you are working in a development environment, the table may be in a state that does not allow certain actions until it is fully defined and activated.
  
  Solution:
  
  
  Activate the Table: Go to the ABAP Dictionary (transaction SE11) and check the status of the table. If it is not activated, activate it.
  
  Open transaction SE11.
  Enter the table name and click on "Display."
  If the table is not activated, you will see an option to activate it. Click on the "Activate" button.
  
  
  
  Check Table Definition: Ensure that all required fields and properties are defined correctly. If any fields are missing or incorrectly defined, complete the definition and activate the table again.
  
  
  Check Transport Requests: If the table was transported, ensure that the transport request was successfully imported and that the table is activated in the target system.
  
  
  Review Authorization: Ensure that you have the necessary authorizations to perform actions on the table. Lack of proper authorizations can sometimes lead to unexpected errors.
  
  
  Consult Documentation: If you are unsure about the table's purpose or its required fields, consult the relevant documentation or reach out to your SAP Basis or development team for assistance.
