Hello,
I have a strange problem in CRM 2015 on-premise.
Recentry I started to get an JS error on form onload (Tried to create new PriceListItem), and onchange for the field "Pricing Method"
I dont have any JS webresources in the form properties so I didnt know where it comes from.
Finally I found out that this error comes from the built in "ProductPriceLevel_main_system_library.js" source so I debug it via IE developer tool and see that is fails at function of "ValidatePricingPercentage".
Then I found that the "Percentage" field is removed (somehow) from the form and there is no way to add it back.
The field is exist in the entity fields list but not display at the Field Explorer in the form editor...
I also tried to reimport this entity from other environment but nothing get change...
Please help
Thanks,
EDIT: I fixed the problem by editing the customization.xml and added those fields manually
