[tryton] reconcile sale pos

[Eduardo J de la Garza G]

Hello,

I get the following error message when trying to use the reconcile sale pos 
wizard in the action menu of sale and sale pos. I'm using tryton 3.4 and 
the modules sale, sale_payment, sale_pos

What could be the problem?

Thanks in advanced,
