I’m using Service Builder to import “ExtenderFileTransferLibrary.rodl” and save the existing RODL. Then I copy Intf.pas, Invk.pas and Impl.pas to project folder and add into the project. But it has the error from client as below. Am I missing something or procedure? If try to doing the “CodeGen”, existing “DataService” will overwrite and setting is lost. How to protect it or what is the correct steps? I’m review the Help that doesn’t mention how to keep the existing coding.
