S3258 - Details

• The SAP error message S3258 indicates that there is an issue with the structure of a node in a table type definition. Specifically, it states that only table names are permitted as node names for nodes of the type 'T'. This error typically arises when you are working with ABAP Dictionary objects, particularly when defining structures or tables.
  
  Cause:
  The error occurs when you attempt to define a node in a hierarchical structure (like a table type) with a name that is not a valid table name. In ABAP, when you define a node of type 'T' (which represents a table), the name of that node must correspond to a valid table name. If you use an invalid name or a name that does not conform to the expected format, the system will throw this error.
  
  Solution:
  To resolve this error, you should:
  
  
  Check Node Names: Review the node names in your table type definition.
