Performance problem:

Invoice Workbench (APXINWKB) Times out when Tax details button is pressed

The function Is_Incl_Tax_Driver_Updatable() is called for each tax line on the invoice when the view tax details
button is pressed, it determines if the tax line can be updated.

The SQL runs in 0.03 of a second, however, there are 1000s of lines/items on the invoice and the
form times out before this can be completed.

I suspect it is the number of invoice distributions that is the issue here (there is 111,474 of them) and that the
form is doing this validation up front when it populates the temp table with the tax lines, rather that at a row level
when the user navigates to them.

The issue can be reproduced at will with the following steps:
1. Navigation: Payables Manager > Invoices > Invoice Entry > Invoices.
2. Query back invoice number XXXXX for supplier number XXXXXXX.
3. Click on the Tax Details button. After some time, the form times out.
