Changing ressources cost

I would like to change the journaly cost of ressources, when i change the cost of each ressources, its take a long time. Sometime its works, sometime i get a error message.

I suppose that every affectation must be change with the new journaly cost, is it possible to change it without error message ?

show the error in log files:
