Revision level in Inspection lot

Hello All,

Below is the scenario followed to create 'Inspection lot' automatically:

We are creating a production order in which one operation is 'externally processed'. After creation, according to customization in order-type dependent parameters, it is automatically creating a 'purchase requisition' which is without material.After conversion of this purchase requisition into purchase order and doing GR for the same, it's creating a 'Inspection lot' of type '0130'.

Now, the Inspection lot created has the material (same as header material of production order), but the issue is that 'Revision level' field is empty in the Inspection lot although material has revision level assigned.

Also, we can see there are two revision level fields in inspection lot:

Kindly let me know how these both fields gets filled in general scenario?

And, also, Is there any option to get 'revision level' for inspection type '0130'?

Thanks in advance.

Regards,
