Smart SAP Assistant

• What is the cause and solution for SAP error message SDDL_PARSER_MSG072 - Name list cannot be used with Select * or $$EXTENSION ?

  The SAP error message SDDL_PARSER_MSG072 indicates that there is an issue with the use of a name list in conjunction with a SELECT * statement or the $$EXTENSION keyword in a query. This error typically arises in the context of SAP's Data Dictionary or when working with ABAP programs that involve database queries.
  Cause:
  The error occurs because:
  
  Name List Usage: In SAP, a name list is a way to specify a set of fields or database objects. However, when you use SELECT *, it implies that you want to select all fields from a table, which conflicts with the specificity required when using a name list.
  Incompatibility with $$EXTENSION: The $$EXTENSION keyword is used to extend the functionality of a query, but it cannot be used in conjunction with a name list that specifies fields.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  *Avoid Using `SELECT **: Instead of usingSELECT *`, explicitly specify the fields you want to retrieve from the database. For example:
  SELECT field1, field2, field3 FROM your_table WHERE condition.
  
  
  Remove $$EXTENSION: If you are using $$EXTENSION, consider removing it or restructuring your query to avoid its use with a name list.
  
  
  Check the Query Structure: Ensure that your query is structured correctly and that you are not mixing incompatible elements (like name lists with SELECT *).
  
  
  Review Documentation: Consult the SAP documentation or help resources for more details on the specific syntax and usage of name lists and the SELECT statement.
  
  
  Related Information:
  
  ABAP Programming: Understanding how to write efficient and correct ABAP code is crucial. Familiarize yourself with the best practices for database access in ABAP.
  SAP Data Dictionary: Knowledge of the SAP Data Dictionary and how it interacts with ABAP programs can help prevent such errors.
  Performance Considerations: Using SELECT * can lead to performance issues, as it retrieves all fields, which may not be necessary. Always select only the fields you need.
  
  By following these guidelines, you should be able to resolve the SDDL_PARSER_MSG072 error and improve the quality of your SAP queries.
