How To Fix OO021 - Interface &2 comprend encore interface &1

SAP Error Message - Details

• Message type: E = Error

• Message class: OO - Class Builder/API

• Message number: 021

• Message text: Interface &2 comprend encore interface &1

Quelle est la cause de ce problème?

You wanted to delete the implementation relationship for interface
&V1&. However, interface &V1& is still implemented in interface &V2&.
Since all interfaces contained in &V2& must be implemented, you cannot
delete the implementation relationship for &V1& unless the
implementation relationship for &V2& is also deleted.
