• What is the cause and solution for SAP error message S1323 - More than one select field ?

  The SAP error message S1323, "More than one select field," typically occurs in the context of ABAP programming when a SELECT statement is improperly defined. This error indicates that the SELECT statement is trying to retrieve multiple fields, but the context in which it is being used expects only one field.
  Cause:
  
  Multiple Fields in SELECT: The most common cause is that the SELECT statement is attempting to select multiple fields from a database table, but the program logic or the context (like a single variable assignment) expects only one field.
  Incorrect Use of SELECT SINGLE: If you are using SELECT SINGLE to fetch a single record but have specified multiple fields in the SELECT clause, this will trigger the error.
  Data Structure Mismatch: If you are trying to assign the result of a SELECT statement to a single variable or a structure that is not compatible with the number of fields being selected.
  
  Solution:
  
  
  Check the SELECT Statement: Review the SELECT statement in your ABAP code. If you are using SELECT SINGLE, ensure that you are only selecting one field. For example:
  SELECT SINGLE field1 FROM table INTO variable.
  If you need multiple fields, you should not use SELECT SINGLE and instead use a regular SELECT statement:
  SELECT field1, field2 FROM table INTO TABLE @DATA(result).
  
  
  Adjust Data Structures: If you need to select multiple fields, ensure that the target data structure (like an internal table or a structure) is defined to accommodate all the fields being selected.
  
  
  Use Appropriate Data Types: Make sure that the variables or structures you are using to store the results of the SELECT statement match the data types of the fields being selected.
  
  
  Related Information:
