Generate Inspection lot operation when needed

Hi

We are using inspection lots to record supplier results for certain raw materials.

We now need to include our own test results to these inspection lots.

To accomplish this we’re thinking of using the same inspection plan with a 2^nd operation.

This will enable us to generate one inspection lot per GR while recording two types of results (i.e. Op1 = Supplier, Op2 = Own).

The inspection lot will always have results from Supplier, but we might only internally test every 10^th delivery (GR).

Is it possible to generate the 2^nd operation (i.e. Own results) when needed?

Or any other elegant approach/process?

Thanks
