data in column B is of 9 or 10 or 11 or 12 digit.
In every case it contains alphabet "P" whereas others are digit.
e.g. 10P060509
125P695847

how can i check this through data validation?

Use this formula in Custom Data Validation:
=ISNUMBER(FIND("P",B1))

Select the cell(s) and using data Validation, choose Custom and enter this
formula:
=FIND("P",B2)0
in this case B2 is the first cell in the range selected of a multiple cell
selection.
It will alert if a P is not in the entry, but won't tell you if several Ps
are entered, just if there isn't one.

It's always worth looking at Excel help.
From Excel help for the FIND function:
"You can also use SEARCH to find one text string within another, but unlike
SEARCH, FIND is case sensitive and doesn't allow wildcard characters."

You should have specified it in your post! This is case insensitive:
=ISNUMBER(SEARCH("P",B1))
