Counting by multiple groups with conditions

[kashun]

Hello,

I have a data which I would like to crate a flag that counts by condition that the about is greater or equal to 300. Else, it should provide a missing

Tried using notsorted with Flag +1 and hash object but keeps not getting what I want. Please advise.

Is the number of different group values known beforehand?

Hi @kashun  Can you please review your results as you seem to continue counting even after change of ID's in the example 342-546 however you seem to be resetting back to 1 in 484??

@novinosrin. Thanks very much. I fixed that.

Works like a charm @novinosrin. Thanks very much.
