Necessary to Model the Status Variable with BOPF?

Hello community,

I want to implement the archiving functionality in a BOPF object and I use this description - so far so good. One point of the description is the modelling of the status variable via TAC SAMDT. My first question: Is it generally necessary to model the variable in this context?

If I start the TAC SAMDT and choose my BO, the node and scheme the program terminated with a dump, because JNet is not installed. My second question: Is a JNet installation on the front-end server necessary to configure the archiving functionality of a BOPF object?

Thanks for hints.

Cheers

Stefan
