• What is the cause and solution for SAP error message NP230 - Field name & is reserved (Do not use structure as include in DB table) ?

  The SAP error message NP230, which states "Field name & is reserved (Do not use structure as include in DB table)," typically occurs when you attempt to use a structure as an include in a database table definition. This is not allowed in SAP because certain fields in structures are reserved for internal use or have specific constraints that prevent them from being used directly in database tables.
  Cause:
  
  Using Structures in DB Tables: The primary cause of this error is the attempt to include a structure that contains reserved fields or is not suitable for direct inclusion in a database table.
  Field Naming Conflicts: The field name you are trying to use may conflict with reserved keywords or system-defined fields in SAP.
  Data Dictionary Restrictions: SAP has specific rules regarding the use of structures and includes in database tables, and violating these rules will trigger this error.
  
  Solution:
  
  Avoid Using Structures Directly: Instead of including a structure directly in the database table, consider defining the fields of the structure individually in the table. This way, you can avoid conflicts with reserved field names.
  Check Field Names: Ensure that the field names you are using do not conflict with reserved names in SAP. You can refer to SAP documentation or the Data Dictionary (SE11) to check for reserved names.
  Use Transparent Tables: If you need to include fields from a structure, consider creating a transparent table that contains the necessary fields instead of using the structure directly.
  Review Data Model: Reassess your data model to ensure that the design adheres to SAP's guidelines for database tables and structures.
