• What is the cause and solution for SAP error message ILM_STOR812 - Name & invalid for data table; name must start with Y, Y, or Z ?

  The SAP error message ILM_STOR812 indicates that there is an issue with the naming convention of a data table in the context of Information Lifecycle Management (ILM). Specifically, the error states that the name provided is invalid because it does not start with the required prefixes.
  Cause:
  In SAP, custom objects such as tables, programs, and function modules are typically required to start with specific prefixes to avoid conflicts with standard SAP objects. The prefixes that are allowed for custom development are usually:
  
  Y
  Z
  
  If you attempt to use a name for a data table that does not start with either of these prefixes, you will encounter the ILM_STOR812 error.
  Solution:
  To resolve this error, you need to ensure that the name of the data table you are trying to create or reference starts with either "Y" or "Z". Here are the steps you can take:
  
  
  Check the Table Name: Review the name of the data table you are trying to use. Make sure it starts with "Y" or "Z".
  
  
  Rename the Table: If the table name does not conform to the naming convention, rename it to start with "Y" or "Z". For example, if your table is named CUSTOM_TABLE, you could rename it to Y_CUSTOM_TABLE or Z_CUSTOM_TABLE.
  
  
  Update References: If you have any references to the old table name in your code or configuration, make sure to update those references to the new name.
  
  
  Transport Requests: If you are working in a development environment and plan to transport your changes to a production environment, ensure that the transport requests are updated accordingly.
  
  
  Testing: After making the changes, test the functionality to ensure that the error is resolved and that the application behaves as expected.
