>
> loan_schedule and customer_attendance are 2 tables which are brought into the 
> Data Warehouse.
> Although there are dates on these tables, I can't find anything sensible that 
> allows me to know the 'system' date that records are added or updated to them.
> A timestamp column is a simple way to allow this.
> Without the timestamp I have to clear down the DW version and copy all of 
> their data over each time.  Not a major problem for small MFI's (even Secdep) 
> but would be for bigger ones.
> It would be best to add this to Release E to get it out of the way and not 
> have it on our backlog.  However, if it isn't done in Release E we'd tackle 
> it the same way we will tackle 1.6 use of DW.  We'd manually add the 
> timestamp before we put the DW live on an MFI (part of the data quality 
> check).  And then when we eventually get round to putting it onto the mifos 
> schema formally... the upgrade has to check that the column isn't already 
> there.
> May be similar thing for PPI surveys but not sure yet (waiting to talk to Van)
> work involved is very simple but we'd have to time it for a big MFI like GK 
> to see how much it might add to their upgrade (I don't think its huge but 
> they are big tables at GK)
