I totally agree with Amol.
I don't think I would touch that development nor would I ever tell a client it could reliably be done through development.
Knowing what I know about the table structures, I don't think you could create any development for this that could use a significant amount of the existing tables and functionality. I think you'd have to create all your own Z tables and basically rebuild the functionality. Tying it back in with SAP data will be difficult.
You're even looking at all custom screens for your results recording and UD as well. And if you have follow-on functions like batch classification requirements, batch determination, COA publication, results copy functions, use of DMR and sampling procedures, physical samples, quality notifications, etc. etc.. you could be looking a whole lot of development.
