I have a set of data containing firms with their annual reports listed by
idnumbers for each company(duplicate cases). Now i´d like to identify the
duplicate cases and set casenumbers to them. Something like the $casenum
function but starting at each PrimaryFirst.
This would then make it possible to for example select "$casenumber 3"
wich will be the annual reports for all the companies three years ago.
Is this possible without to much hazzle??
