I have a popup LOV which needs to be dynamically populated based on user search. Data volume for the LOV is huge and comes from REST data source. So a filter is needed to faster the search.
With an external filter as substringof('XXXX',ID) the results can be fetched. Here, XXXX is static. My requirement is to make the search dynamic and when every time the user starts search, the search value of popup LOV has to be passed instead of XXXX.
How this can be achieved?
