Unifier Webservices to update datapickers in the detail form. Currently only supported in Upper form
Today we have tested in version 17.12.x and Webservices function updateBPRecordV2 doesn't allow DataPicker updates in LineItems / Details Forms.
There are many other Data Elements that are getting updated, just the DataPicker types are not.
The DataPickers are gettting updated in Upper form fine.
