Alternative to MAX
is there any function which gives us max of values in terms of strings?
not integer 0's and true or false
it should return the column value.

You can use LASTNONBLANK to return the 'maximum' of a text column.

Hi Anonymous,
That's right, LASTNONBLANK/FIRSTNONBLANK order text lexicographically.
If you want the text value with greatest length, you can do this or something similar:
Longest Text Value = CALCULATE ( LASTNONBLANK ( MyTable[TextColumn], 0 ), TOPN ( 1, VALUES ( MyTable[TextColumn] ), LEN ( MyTable[TextColumn] ) ) )If there are ties, they are broken by LASTNONBLANK.
