Help with remove duplicate content and only keep the first content detail

Input
Code:
data_10 SSA
data_2 TYUE
data_3 PEOCV
data_6 SSAT
data_21 SSA
data_19 TYUEC
data_14 TYUE
data_15 SSA
data_32 PEOCV
.
.

Desired Output
Code:
data_10 SSA
data_2 TYUE
data_3 PEOCV
data_6 SSAT
data_19 TYUEC
.
.

From the above data, if the data in column two is same (eg. data_10, data_21, and data_15 all got SSA), I would only keep the data which appear first (eg. keep data_10 SSA, remove data_21 SSA, and data_15 SSA)
Thanks.

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
