databaseManager.recalculate possible a less expansive way?

[[email protected]]

Hi to all,
we have a relation order_to_order_lines in a form of name Orders wich contains the tabpanel of the relation above.
The amount_field of the order is placed in the form Orders, and after a new record in the tabpanel we need to use "databaseManeger.recalculate", in order to update the amount of the order. But it is too much expensive (many minutes the first time we insert th first record in the tabpanel).

Any idea?

Tanks in advance.

How many related records are there to recalculate? Surely not that many for the "minutes" that you mention.
Have you tried doing a recalculate on just the one record rather than the whole foundset (of the relation)?
Is the amount that you talk about the sum of all the order lines = the aggregate sum of each order line? And do you use the aggregate capability?

No I didn' t but I'll try.IT, OF SURE WIL BE BETTER than the command wich, in the while i gave with a good effect:

Code: Select all

order_to_lines_order.loadRecords();
