• What is the cause and solution for SAP error message DT407 - Tables of type & may not be included ?

  The SAP error message DT407 indicates that certain tables of a specific type cannot be included in a particular operation, such as a transport request or a data dictionary operation. This error typically arises when you are trying to include a table that is not allowed to be transported or modified in the way you are attempting.
  Cause:
  
  Table Type Restrictions: The error often occurs because the table you are trying to include is of a type that is restricted from being transported. For example, certain system tables or temporary tables may not be allowed.
  Table Attributes: The table may have specific attributes set that prevent it from being included in transport requests, such as being a cluster table or a pool table.
  Development Class: The table might belong to a development class that is not transportable or is marked as local.
  
  Solution:
  
  Check Table Type: Verify the type of the table you are trying to include. You can do this by checking the table definition in the Data Dictionary (SE11). If it is a cluster or pool table, you will not be able to include it in a transport request.
  Review Attributes: Look at the attributes of the table to see if there are any restrictions that prevent it from being included. You may need to change the table type or attributes if appropriate.
  Development Class: Ensure that the table is assigned to a transportable development class. If it is assigned to a local development class, you may need to create a new transportable development class and move the table there.
  Consult Documentation: Refer to SAP documentation or notes related to the specific table type and its transportability. There may be specific guidelines or exceptions noted by SAP.
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is a critical table or if you believe it should be transportable.
  
  Related Information:
