You have created Case # 644239 for this issue. I believe part of the question has been cut off on the title field, the full question looks to be the following:
I have a query regarding the changing context in processbook displays. Suppose there are four network health tab. On clicking each of them, a new tab opens in same display. Since each of them have similar attributes, everytime same tab will open. But the values of attributes will be different for each of them. So how will I do it using Backend vba coding? Also is there any way that I could make my display look more fancy and better?
As suggested by our Technical Support Engineer, the functionality can be achieved out-of-the-box via Element Relative Display (if you are using element template for these attributes). This solution is scalable and requires no custom coding. If we have misunderstood your requirement, please elaborate and we can offer a better suggestion.
Regarding your second question, you can perform many customization with the tools offered in PI ProcessBook. If additional features are required, you can look into VBA coding.
