Affected Version: Ephesoft Transact 4500 / 4501
Component: Rest API Lookup Search on Validation UI Screen.
On validation Screen when customer is doing a rest api lookup for a specific field and retrieving results successfully then the same is removing the values of already extracted index fields.
Above issue is confirmed as a bug and is will be fixed in later ephesoft versions (Version is not decided yet). The only workaround is to write custom implementation in Ephesoft Scripts.
