Hi all,
I found this issue while using Eikon R library. Do understand that's not formally supported here, but I believe the underlying issue is with API/proxy rather than R.
When get_data returns a table with columns that contains NULL, NULL values are not inserted properly and the results from get_data would not match what one would get from Eikon/Excel
JSON request:
{"Entity":{"E":["DataGrid"],"W":{"instruments":[["0388.HK"]],"fields":[{"name":["TR.EPSEstValue(Period=FY2019)"]},{"name":["TR.EPSEstValue(Period=FY2019).date"]},{"name":["TR.EPSEstValue(Period=FY2019).origdate"]},{"name":["TR.EPSEstValue(Period=FY2019).confirmdate"]},{"name":["TR.EPSEstFootnote(Period=FY2019)"]}]}}}

Here both confirmdate and footnote columns can (and do contains) NULL. Instead of having NULL inserted into the correct rows. The reply simply put the non-NULL values at the top/head of the column and fill the rest with NULL.
