Scheduled pick bug?

Hi,

   Did anybody else encounter this issue?

   When creating an SO (using Delivery date preference) the scheduled pick is modified back to the original date if the user repeatedly changes the quantity on the SO without saving (change the quantity then jump to next row).

  Steps to reproduce:

   Create an SO and enter a request date. Save the SO. Enter the SO again and change the promised delivery date (blank out scheduled pick and promised ship to have them recalculated). Save the SO. Enter the SO again, change the quantity and jump to next line. The scheduled pick is the same. Now change the quantity again and jump to next line. The scheduled pick is back to the original date.
