• What is the cause and solution for SAP error message /UI5/MP_CA_OVP003 - Card with id &1 already exists in base desciptor ?

  The SAP error message /UI5/MP_CA_OVP003 Card with id &1 already exists in base descriptor typically occurs in the context of SAP Fiori applications, particularly when dealing with the configuration of cards in the Overview Page (OVP) or when using the SAP UI5 framework. This error indicates that there is an attempt to create or register a card with an ID that has already been defined in the base descriptor.
  Cause:
  
  Duplicate Card ID: The most common cause of this error is that there is a duplicate card ID being defined in the application. Each card in the OVP must have a unique identifier.
  Configuration Issues: There may be issues in the configuration files (like manifest.json) where the card definitions are specified.
  Caching Issues: Sometimes, caching can lead to this error if the application is not picking up the latest changes.
  
  Solution:
  
  
  Check Card IDs: Review the card definitions in your manifest.json or any other configuration files to ensure that each card has a unique ID. Look for any duplicate entries and resolve them by renaming the card IDs.
  
  
  Clear Cache: If you have made changes to the card definitions, clear the browser cache or use the "hard refresh" option (Ctrl + F5) to ensure that the latest version of the application is loaded.
  
  
  Check for Multiple Instances: If you are using a custom component or have multiple instances of the same card, ensure that they are not trying to register the same ID.
  
  
  Review Base Descriptor: If you are using a base descriptor for your cards, ensure that the card IDs defined in the base descriptor do not conflict with those defined in the derived descriptors.
  
  
  Debugging: Use the browser's developer tools to check for any additional error messages or logs that might provide more context about where the duplication is occurring.
