This error indicates that the system expects you to specify which fields from a particular table you want to work with, but none have been provided.
  Cause:
  
  Missing Field Specification: The most common cause of this error is that the user has not specified any field names when trying to access or manipulate data from a database table.
  Incorrect Query Definition: If you are using a query tool (like SAP Query or InfoSet Query), the query may not have been properly defined to include the necessary fields.
  Programmatic Errors: In custom ABAP programs, if a SELECT statement or a data declaration does not include field names, this error can occur.
  
  Solution:
  
  
  Specify Field Names: Ensure that you specify the required field names in your query or program. For example, if you are using a SELECT statement in ABAP, it should look something like this:
  SELECT field1, field2 FROM table_name INTO TABLE @DATA(result).
  Make sure to replace field1, field2, and table_name with the actual field names and table you are working with.
  
  
  Check Query Definitions: If you are using a query tool, go back to the query definition and ensure that you have selected the fields you want to include in your output.
  
  
  Review Program Logic: If you are working with custom ABAP code, review the logic to ensure that all necessary fields are included in your data operations.
  
  
  Consult Documentation: If you are unsure about the required fields for a specific table, refer to the SAP data dictionary (transaction SE11) to view the structure of the table and the available fields.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or SQ01/SQ02 (SAP Query) to investigate the table structure and query definitions.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  Field Names: Familiarize yourself with the specific table you are working with to understand which fields are mandatory and which are optional.
