I have a error in module sale\_stock\_quantity when I process a sale of product and I don’t have any product in warehouse , and that return a message that “The forcast quantity -5 of is lower than 1” and the should return -1 , often tried with more products and I get things something like this ![erro-5](https://discuss-cdn.tryton.org/uploads/default/original/1X/3a1b1344dd3bf5d7de1b9ceff19b3f34e5e4ce63.png) ![error0](https://discuss-cdn.tryton.org/uploads/default/original/1X/3b718221ecf2eb7bd01982cff120f1f29fabf35f.png) ![error-1](https://discuss-cdn.tryton.org/uploads/default/original/1X/0e9c5d57c4a4daa948f45d10420b4bedf764eed7.png) ---

> [@Yessica](#): > > The forcast quantity -5 of is lower than 1 Forecast quantity is in the future (cantidad prevista) Also I have doubts all screens that show “Alm\*”. I think “Alm” is a warehouse name (Almacén). Check the context that calculate those fields. ---

Could you reproeudce the steps on a fresh databse with only sale\_stock\_quantity module installed? If so, please [fill a bug](https://bugs.tryton.org) with the steps to reproduce it. Thanks ---

The sale\_stock\_quantity module takes also in the computation of the quantity the other sales in quotation and confirmed. ---

> [@Yessica](#): > > the version is 4.2 , Take care that version 4.2 is unsuported since we released version 5.2. You should consider upgrading to newer serires. The time each relase is supported is described on [Proposal for a new release process](https://discuss.tryton.org/t/proposal-for-a-new-release-process/454) . You should consider using a long term support version if you want to reduce the need of upgrade. ---
