I'm steadily progressing with my conversion of my Access accounting system to a Linux based system.

I've moved from using mysql to postgresql which has made a few things easier by having VIEWs in the database.

Rekall seems to have most of what I need on the forms and reports front except for one thing - I can't see how to implement a 'running total' column.

The Access97 report tool has a specific 'running total' column type which does exactly what I need. Rekall doesn't have anything like this (that I can see).

Has anyone got any bright ideas of how I can do this, it's rather vital on things like a Bank Reconciliation report to enable me to check my accounts against the bank statement.
