Why valuate batch characteristics

Hello all,

I am currently doing some research around Batch Derivation, and keep coming up against the same question. I have worked for sites that require all results from an inspection lot to be sent to the Batch Characteristics, and I have have seen where only a select few MIC's used for costing need to be linked.

Can someone please explain why a client would need every single MIC to be linked to a Batch Characteristic? (Note: assume no potency / active ingredient requirement)
