Hi Bill,
The "Contribution" (and "Withdrawal") columns in the Portfolio Performance report will often not add up to the total shown for the portfolio. The information for these columns is specific to that line item, not the sub-portfolio. So, for example, if you use cash in your account to buy some stock for $1,000 the cash investment will have a withdrawal of $1,000 and the stock will have a contribution of $1,000 but the sub-portfolio line will have $0 for both contribution and withdrawal, since at the sub-portfolio level nothing was contributed or withdrawn.
If the sub-portfolio contribution/withdrawal figures are not as you expect, you can see why by creating an "Investment Transaction" report for that sub-portfolio, and in the "Filter..." options check "Include Only Portfolio External Transactions (Contributions/Withdrawals)". In the example above, neither the sell of cash or buy of the stock would be listed, as those were "internal" to the sub-portfolio. Fund Manager determines internal/external by matching up amounts/dates. For more on this, you can read:
