Issue in Performance based Inspection for PRT and Inspection lot creation

  Dear Experts,

                               My
requirement is as follows,                          
For an Material procured from the vendor,  the Vendor utilizes an PRT for manufacturing
the material. Our Quality inspector needs to inspect the PRT once the PRT has
produced 300 Each of components, as the PRT is an asset of company and provided
for vendor

                                
I have created an PRT with category - P in IE01 and I have created the
Measuring Point (Counter) in IK01 with target value as 300 Ea (Indicator as
measuring point as counter) and Equipment task list is also created with
Inspection points , Master Inspection characteristics for the PRT. Usage value
and formula also updated in for the PRT formula parameter

   I have also created Maintenance plan for
this PRT with cycle of 300 Ea

                         
Quality Inspection plan is also created with usage "5" - Goods
Receipt and I have assigned the PRT.

   When I make the Goods Receipt for 350
Ea with reference to the Purchase Order and I have done the Result
recording / Usage decision for an Inspection lot, but the Inspection lot is not
getting created with inspection type 14.

  I have executed the scheduling of
maintenance in IP10 and IP30

   I want the automatic generation of
Inspection lot when the GR is done more than for 300 Ea in order to inspect the
PRT

  Please suggest, where should I check
