Hi Vemuri,
Thanks for you prompt reply. This is the process:
1) The purpose is to service a vehicle that is still under a service plan.
2) It is claimed through a warranty vehicle not because it is still under car warranty period (which is a different scenario), but because a dealer is claiming the amount of the repair cost they had performed to a vehicle, which the vehicle owner has bought the service plan sold by the distributor of the brand.
3) Warranty will be raised against a vehicle, which will have identification number, known as VIN. This corresponds to the field Ext. Obj. No., with Obj Type VELO. Refer below:
However in equipment, it will have its own Equipment Number which is different from Ext. Obj. No. The VIN number is recognized only as description field in IE02. Refer below:
4) Warranty will have a 'validation/check' before it could proceed. For this particular scenario, it will be validated against the service contract number, which I believe will be tied to Equipment number instead of the VIN number (integration between SD-PM/CS).
5) The rest of the warranty claim process will happen after the plan<->vehicle relation has been validated (contract/plan exist,still valid within that day), which is not important in this discussion context.
EDIT:
Additional Notes
The vehicle is uniquely identified as VIN, in VLCVEHICLE table (VMS module), thus it does not have serial number. The reference material description's is as in the 'Model' field.
