The requirement isn't so strange. Imagine a service bay where complex machine checks are carried out. Form 1 documents the principal service operation very similar to the one shown in our COMPLEX FORM example. BUT certain of the items require a report on sub-assemblies which come from a different supplier, and have individual forms to the design/requirements of the subsidary suppliers. This means the service engineers have to skip back and forth between the forms - or user three tablets, which is a ridiculous solution. So we provide an option to work on all three forms at once as if they were all one big (multi-page if necessary) but you can still access each form individually if you want. The result is time saving and simpler for the engineers but also easier to control for the system managers.
