Hello,
Can anyone please help me out for following issue ?
Thanks for your time to look on..
Referring to your feedback in that thread, did you index your column while the threshold was 5000 items or 10000 items? If I remember correctly, you cannot index a column if your total number of items exceeds the threshold.
If this is the case, try to expand your threshold limit to 10000, then create your index, then bring the threshold back to 5000, then try your “group by” again.
