today I want to document in my blog interesting behavior of PXFilter in Acumatica.
First of all, few words about it's behavior. If Acumatica sees PXFilter, it will create single record, which will remain only in cache and never will travel to the db. Recently I faced interesting issue, fields from PXFilter DAC object was updated only once. After deep investigation I've found that it is because anything that works with PXFilter shouldn't have any field marked as IsKey. If field is marked as IsKey, it will not be updated after each modification of UI.
