Product card and Offer card are and should be independent from each other at many points.
There are many reasons for this. “Customer Price Policies Rules” is one of them.
Ultimately, if you want to update the price from the “product card” and want to update the prices in the “Customer Offers” from here, it is quite a problematic task.
However, as you know, you can always update the prices of the lines in “Bids”.
So there is no possibility to update the product prices afterwards?
Just image, you made a new customer offer, after 2 weeks, the price of your products (e.g. 30 different products) changed somehow. I would than need to make a whole new offer, or update the price of every single item in the offer by hand. Is this the only way?
yes, but it requires a coder that uses the API to find all Proposals with this product and then update those Proposals to reflect the new price of the changed products.
