• What is the cause and solution for SAP error message /UI5/DTA019 - App variant id should have 'customer.' prefix ?

  The SAP error message /UI5/DTA019 App variant id should have 'customer.' prefix typically occurs in the context of SAP Fiori applications when dealing with app variants. This error indicates that the application variant ID you are trying to use does not conform to the naming convention expected by the system.
  Cause:
  The error arises because SAP requires that custom app variants (those created by users) must have a specific prefix, in this case, customer.. This is a part of the naming convention to differentiate between standard SAP variants and customer-specific variants. If the variant ID does not start with customer., the system will reject it and throw this error.
  Solution:
  To resolve this error, you need to ensure that any app variant IDs you create or use start with the prefix customer.. Here are the steps you can take:
  
  
  Check the Variant ID: Review the variant ID you are trying to use and ensure it starts with customer.. For example, if your variant ID is myVariant, you should change it to customer.myVariant.
  
  
  Create a New Variant: If you are creating a new variant, make sure to follow the naming convention from the start. When prompted for a variant ID, always include the customer. prefix.
  
  
  Modify Existing Variants: If you have existing variants that do not conform to this naming convention, you may need to rename them to include the customer. prefix.
  
  
  Check Configuration: If you are working with a custom application or have made changes to the Fiori app configuration, ensure that the app variant handling is correctly set up to enforce this naming convention.
