This error typically arises in the context of using the ABAP Development Tools (ADT) in Eclipse or when working with CDS views in the SAP system.
  Cause:
  
  
  Missing Metadata Extension: The specified metadata extension (indicated by &1 in the error message) does not exist in the system. This could be due to:
  
  The extension was never created.
  The extension was deleted or not activated.
  There is a typo or incorrect reference in the CDS view or the associated code.
  
  
  
  Transport Issues: If the CDS view or its extension was transported from another system, it may not have been transported correctly, leading to missing objects.
  
  
  Authorization Issues: The user may not have the necessary authorizations to access the metadata extension.
  
  
  Solution:
  
  
  Check Existence: Verify if the metadata extension exists in the system. You can do this by:
  
  Navigating to the relevant package or using transaction SE11 (Data Dictionary) to check for the existence of the extension.

  Create or Activate the Extension: If the extension does not exist, you may need to create it. If it exists but is not activated, activate it.
  
  
  Check Transport Requests: If the extension was supposed to be transported, check the transport requests to ensure that all necessary objects were included and successfully imported into the target system.
  
  
  Review Code: If you are referencing the extension in your CDS view or ABAP code, double-check the syntax and ensure that the reference is correct.
  
  
  Authorization Check: Ensure that the user has the necessary authorizations to access the CDS objects. You may need to consult with your security team to verify this.
