Basically I have two groups of data
Group 1 is machine info and has
Serial Number Build Month Commission Month
Group 2 is warranty info and has
Serial Number Service Claim Value of Service Claim
What I need to do is for all machines built in a given month count the number of claims within a given number of months after commissioning and the total value of the claims.
Eg
If I have a machine serial number abc123 built in jan 07 and commissioned mar 07 I need to search the table of data in group 2 for the number of claims between mar 07 and may 07 and also the total value of those claims
If you have any suggestions it would be a great help.
Thanks
Colin
