Warranty work / field Service

Looking for ideas to address the current situation. Capturing and posting
cost to closed jobs that require field service, or Warranty work. The
accountants would like to see the cost reflected on the job it relates to,
with reason codes for the work performed, and all cost expensed to a
warranty account. I have not played with projects before, would it be best
to created a new job with a War suffix / prefix ?, and link it to the
original job using the project function?.

Thanks
