• What is the cause and solution for SAP error message /UI2/PAGE057 - The ID must start with Z or Y and may be up to 32 characters long. ?

  The SAP error message /UI2/PAGE057 indicates that there is an issue with the ID of a custom Fiori application or UI5 application. Specifically, the error states that the ID must start with either "Z" or "Y" and can be up to 32 characters long. This is a common requirement in SAP systems to differentiate custom objects from standard ones.
  Cause:

  Solution:
  
  Change the ID: Ensure that the ID you are using for your custom application starts with "Z" or "Y". For example, if your current ID is ABC123, change it to ZABC123 or YABC123.
  Check Length: Make sure that the ID does not exceed 32 characters. If it does, shorten it while still maintaining its uniqueness and relevance.
  Review Naming Conventions: Follow the naming conventions established in your organization for custom developments to avoid conflicts and ensure clarity.
  Testing: After making the changes, test the application again to ensure that the error is resolved.
