Vendor Quote Maintenance

Those of you that are familiar with the vendor quote maintenance
program, can I please get you input on this situation. 

 

First of all we don't have the source for the program and we needed a
way to capture changes the users make so the purchasing manager could
approve the changes before they are to be used. So what I did was to
create a few programs to capture the changes using a trigger program and
then a new inquiry screen allows the manager to approve the changes and
then I go out and activate the records. This has been working to a point
but problems arise every now and then. 

 

My question is I am thinking of writing a new program like the vendor
quote maintenance so I can control the user fully. Right now the user
can made duplicate changes to the same quote and I have problems
replacing the data because the program deletes the record and replaces
it when the disc date is changed. 

 

So if you're familiar with the program can you tell me if it does
anything special except maintain the fields on the screen in the HQT
files?

 

Thanks for you help,

Daniel
