Many thanks for the reply.
We currently maintain stock level control via our accounts software, and have done so for many years. The problem we have is that the guys in the workshop have no user rights to access this programme (security reasons). What i am trying to introduce is a system so the chaps in admin know excatly who,what, and when to invoice a customer, after a clients machine has gone through our workshop. Filemaker is accessed in all departments of the business, and once the guys in the workshop carry out a job, he can print a record (job) from the SERVICE RECORDS file, and hand to accounts for them to sort out.
My SERVICE RECORD file contains information about individual workshop jobs, client machine repairs, also our own machine repairs and warranty works.
Parts Orders records are line items to be used via the portal in SERVICE RECORDS file, linked via the job number relationship.
This is about as far as i have progressed, with no Parts tracking (number bought, number sold etc). At the moment stock level control is not reliable.
As i said in my post, Filemaker is new to us her, and i would eventually like to have our accounts software / Filemaker integrated.
