Warrenty contract need to generate based on RMA Line

We are in compressor business and leadtime of repair is 30days. Customer cant wait till the time, Hence we will give the availabel model as replacement.

insted of same compressor against RMA.

For inwarrenty we  need to pass the balance warrenty contract on the repaired compressor.

i.e of fresh comperssor had 18 months warrenty,

Customer return to  business after 6 months due to failuer.

the remaining 12 months warrenty need to pass on replaced compressor during replacement.

The  problem is - when we issue out defective comperssor (RMA) its warrenty get terminated due to MISC Issue.

Hence balance warrenty not get transfered to repaired compressor given aginst that (Ship) Line.
