I am creating my first ever App in Zoho, using a number of Sub-Forms as my one-to-many relationships, and also to create one "Master Form".

 

Would I repeat my Primary Key Field on each Sub-Form as a Look-up Field, to accommodate "Auto Filtering"reporting from a field on one of the Sub-Forms when creating a Report from the Master etc?

Would I need to repeat other Fields from the Master or other Sub Forms to also accommodate this?
