Hi,

We have a wide SharePoint list (150+ columns) which is causing issues on our farm.

We are looking to logically group the data into smaller lists related by a single reference number.

We use InfoPath to customize the list forms and, ideally, we'd like to be able to update the list data from a single place.

Is it possible to customize the list form for one of the lists (the 'main' list storing the overall details) and be able to update the other list forms on separate tabs with separate data connections?

I haven't had success trying to do this and am considering an alternative approach: a web part page displaying the main list and connected web parts for each of the related lists but this isn't ideal.

Any suggestions are welcome

Thanks,
