Full Update/Delta Process

I did a full update of data into an ODS object as instructed by the best practice manual for my scenario.

If I understand correctly, this now stops me from initializing the delta process?

As I want the ODS to be updated every day, I have deleted the initial request from the ODS and the InfoCube which the ODS updates.

However, when I now try to create an InfoPackage to initialize the delta process I receive a message telling me to delete the initial request first. There is no initial request any more!

Do you know where else the initial request might be?

Also, after I have run the delta initialization, presumably I schedule the same infopackage to run every night?
