I have a function that calculates the recommended purchase order quantity for a stock item based off various other values and functions: pqty(stock.code) AS "pqty" This needs to be rounded up / down to the nearest multiple of the purchase unit quantity for that product - It's Friday afternoon and my head has refused to help me work out the maths all afternoon!

Hi again,

Same SELECT query as before, = different area of it… I have a function that calculates the recommended purchase = order quantity for a stock item based off various other values and = functions:

pqty(stock.code) AS "pqty"

This needs to be rounded up / down = to the nearest multiple of the purchase unit quantity for that product = – It’s Friday afternoon and my head has refused to help me work out = the maths all afternoon!

Example:

Pqty =3D 60

Purchase Unit =3D 25

Pqty needs to be rounded down to = 50.

I guess I’m also asking if I = should do this in the Pqty function or in the SELECT query to optimize the = result?

Thanks all – Enjoy your = weekends I hope!

Cheers,

-p
