David,
He doesn't even make sense. Suppose an order line item gets inserted into the wrong order. Are we to believe nobody can correct this by assigning the surrogate for a different order to the line item?
If not, the feature strikes me as useless in the first place. If so, he doesn't have a clue what he's talking about. Received on Sat Jan 05 2008 - 15:16:23 CET
