Hi all,

I'm trying to insert a column into addons/purchase/report/order.rml so that every line of the purchase order starts with a consecutive number.

The trouble is that the report uses data from the database and these numbers are neither there nor shall be there. The only sensible thing to to would be to generate these numbers on the fly for every report.

I tried to do this in the RML file itself but this does not work. It seems that the code executed between the square brackets is local for this execution - I cannot define a "global" variable, increment it and print it's value on each row. I searched the internet but cannot seem to found an answer. How shall I go about this problem?

Thanks in advance!
