IFS Cloud 23.2.9

We are managing standardized parts which are certified by an accredited certification.

This involves, after qualification, a freeze on the configuration of those parts and only one person in the company is empowered to modify any data on such a part. 

So, the objective is to freeze (block modifications) all the data we have on master part, inventory part, product structure, routing, purchase part, SFPP and sales part considering that many people can interact on these projections for classic parts

Any idea to manage access/rights on many projections but only for some parts ? or is someone already got this need ?

Thanks for your help
