If your club has re-bought a stock that it previous owned, and would like the records to reflect the recent re-purchase on reports that show a first purchase date, try the following:

Go to Accounting > Utilities > Update Club Settings.
From here, change the Include Earlier Ownership radio button to NO, and then click the CHANGE button.

As long as the stock was previously sold off and had zero shares and zero cost, the system will now reflect the new purchase date instead of the original one.
