HI, all
I encounter a new problem. it's urgent to get your help. I have take a long time to resolve it. The following is the problem's description:
A Customized item can be derived form a standard item, this link can been created via copy a standard item to a Customized item. and I can unlink them by click the button "unlink der. item" on tab "engineering". then how can I to link them again. In BAANIV , the derived field can change anytime. but In BAAN V , this field is grey and cannot be changed.

I am looking forward to your reply.

Benny :)
