• What is the cause and solution for SAP error message VO220 - Enter a table from the customer namespace ?

  SAP Error Message:
  
  VO220 - Enter a table from the customer namespace
  
  Cause:
  The error message VO220 occurs when you try to enter or use a table name that does not belong to the customer namespace in SAP. In SAP, customer-specific tables must be created in the customer namespace, which typically starts with the letter 'Z' or 'Y'. This naming convention ensures that custom developments do not conflict with standard SAP objects.
  If you enter a table name that starts with any other letter (i.e., standard SAP namespace), the system will raise this error to prevent overwriting or interfering with SAP standard tables.
  
  Explanation:
  
  Customer namespace: Tables created by customers or partners should start with Z or Y.
  Standard SAP namespace: Tables starting with other letters are reserved for SAP standard objects.
  The system enforces this to maintain the integrity of SAP standard objects and avoid conflicts.
  
  
  Solution:
  
  Use a table name starting with 'Z' or 'Y': When creating or referencing a custom table, ensure the table name begins with Z or Y.
  Check the table name: If you are entering a table name manually, verify that it follows the customer namespace naming convention.
  Create a new custom table: If you need a new table, create it in the ABAP Dictionary (transaction SE11) with a name starting with Z or Y.
  Avoid using standard SAP table names: Do not try to create or modify tables that belong to the SAP standard namespace.
