Hi, I asked this question in an earlier thread but I guess the data was too confusing, so simplifying it into a sample datas:

I have a dataset that has the financial data recorded monthwise over a span of a few months. Let's say each enterprise has 3 months of financial data recorded, but the data collection isn't necessarily uniform i.e for some enterprises, data can be of Jan-Feb-Mar, for some it can be Mar-Apr-May

For the months where no data was recorded, the data entry is marked by '0'

input int ID byte(sales_Jan cost_Jan tax_Jan misc_Jan sales_Feb cost_Feb tax_Feb misc_Feb sales_Mar cost_Mar tax_Mar misc_Mar sales_Apr cost_Apr tax_Apr misc_Apr)

7896  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0
1235  0  0  0  0 40 60 20 40 20 90 20 10 50 20 50 20
6954  0  0  0  0  0  0  0  0  0  0  0  0 50 80 20 60
1254  0  0  0  0  0  0  0  0  0  0  0  0 40 20 40 40
end
I ideally wanted variables that look like sales_month1 cost_month1 tax_month1 and so on

Is this possible?
