In the new 2020.1 release, forms like Opportunity, Sales Order, Vendor Bill, Opportunity, Sales Order, Vendor Bill, Vendor Return Authorization have an issue with the subsidiary field. When the sub-lists in either of these forms are in expanded mode, the Subsidiary field is sourced in automatically on choosing the value for Vendor field. Due to this, the form throws an error on saving. It has been observed that the subsidiary auto fills the value if the sub-lists on these forms are in collapsed mode. We have the error screenshots from one of our leading environments where we faced this problem.
