• What is the cause and solution for SAP error message DDLS456 - At least one column, apart from the client column, must be specified ?

  The SAP error message DDLS456 indicates that when you are trying to create or modify a database table, you have not specified any columns other than the client column (which is typically the MANDT column in SAP). This error usually occurs in the context of Data Dictionary (DD) operations, such as when you are using the Data Dictionary tools (like SE11) or when executing a Data Definition Language (DDL) statement.
  Cause:
  The primary cause of this error is that the table definition lacks any user-defined columns apart from the mandatory client column. In SAP, every table that is client-dependent must have a client field (MANDT), but it also needs at least one additional field to be meaningful and functional.
  Solution:
  To resolve this error, you need to ensure that you define at least one additional column in your table definition. Here are the steps to do this:
  
  
  Open the Data Dictionary (SE11):
  
  Go to transaction code SE11 in your SAP system.
  
  
  
  Select the Table:
  
  Enter the name of the table you are trying to create or modify.
  
  
  
  Add Columns:
  
  In the table definition, ensure that you have at least one additional column defined apart from the MANDT column. You can add fields by specifying their names, data types, lengths, and other attributes.
  
  
  
  Save and Activate:
  
  After adding the necessary columns, save your changes and activate the table.
  
  
  
  Check for Other Errors:
  
  If you still encounter issues, check for any other errors or warnings in the table definition that might prevent activation.
  
  
  
  Related Information:
  
  Client-Dependent vs. Client-Independent Tables: Understand the difference between client-dependent and client-independent tables in SAP. Client-dependent tables have the MANDT field, while client-independent tables do not.
  Data Dictionary (DD): Familiarize yourself with the Data Dictionary in SAP, as it is crucial for defining and managing database objects.
  Field Attributes: When defining fields, pay attention to their attributes (like data type, length, and key status) to ensure they meet your application requirements.
  
  By following these steps and ensuring that your table definition includes at least one additional column, you should be able to resolve the DDLS456 error.
