Make sure you have the correct OPERA Cloud settings in Proposales:
Currency
Make sure the correct Currency is is set up in Proposales: Settings-> Company.
If products are imported in the wrong currency, all products need to be deleted and added again after the correct currency setting is set.
Configure your OPERA Cloud settings
In Proposales navigate to your settings and click on your OPERA Cloud settings. Here you have the possibility to adjust your default settings that will be used for your proposals.
First, set up a desirable flow of the proposal, from the initial stage when a proposal is sent to accepted or lost.
Make sure that the selected Initial status and Initial Reservation Type both have the same set up in Opera as non deductive or deductive. If they contradict it will cause errors.
The Source Code, Rate Code and Market Code that you define in this Page will be the initial default options. You can always define the default later on per Template and even change it manually in each proposal whenever needed.
