[GNC] Error on Advanced Portfolio Report

[Danilo Freitas da Costa]

Hi everyone!

I'm facing an issue with in Advanced Portfolio Report:

*There is an error processing the transaction 'buying 100.0000 share
units'. This may to be caused by a sell transaction causing a negative
stock balance, and a subsequent buy transaction causing a zero balance.
This leads to a division-by-zero error. It can be fixed by preventing
negative stock balances.*

I looked for the cause and I found it. But I don't know how to solve it.

This problem is caused by a sequence of stock register (just this specific
stokc):

* Jan 12 - Sell 200 Stock XXX
* Jan 12 - Buy 100 Stock XXX

Until now, no problem. The report works well. Then I finish this operation:

* Feb 17 - Buy 100 Stock XXX

When I register this last operation the problem happens.

I don't understand that, because I have other operations like this one and
the report always works well.

To avoid any data entry error, I removed all transactions and inserted them
again.

Do you have any idea how to solve that?

Thanks!

Att,
Danilo
