Disable auto prorating of invoices matched to PO with multiple distribution lines option.

In the standard functionality, when a AP invoice is matched to a PO line with multiple distribution lines,  the system prompts the user to determine if they want to prorate the amount across the distributions.  If the users selects "Yes" the system prorates the billed amount across the distribution lines calculating out to 14 decimal places. When this PO line is closed the system leaves a small balance on the PO due to the rounding of the decimal places.

If the users selects "No" to the system prompt, the user is allowed to enter the amounts to the various distribution amounts manually.  There are no rounding issues and when the PO is closed there is no amount remaining.
