Awk multiple lines with 4th column on to a single line

This is related to one of my previous post.. I have huge file currently I am using loop to read file and checking each line to build this single record, its taking much much time to parse those records.. I thought there should be a way to do this in awk or sed.

I found this code in this forum and I think it's closed to my request.
Code:
nawk 'BEGIN {FS="|"}END{for(r in _)print r FS _[r]}{idx=$1 FS $2;_[idx]=_[idx]?_[idx] FS $3:$3}' myFile

I changed based on my request but I can't get this worked.. Can any one Please help me on this. Much much appreciated.

Input file:
Code:
XXXXXXXXXX1|07/24/2007|1|aaaaaaaaaaabbbbbbbbccccccccccccc
XXXXXXXXXX1|07/24/2007|2|sometxt
XXXXXXXXXX1|07/30/2007|1|some_random_text
XXXXXXXXXX1|07/30/2007|2|new_random.
XXXXXXXXXX1|09/27/2007|1|some_nre_random_test
XXXXXXXXXX1|09/27/2007|2|blabla
XXXXXXXXXX1|09/27/2007|3|fixed_text_random
XXXXXXXXXX1|11/14/2007|1|blabla
XXXXXXXXXX1|11/28/2007|1|junk_text
XXXXXXXXXX2|12/21/2007|1|Notes

Code:
XXXXXXXXXX1|07/24/2007|aaaaaaaaaaabbbbbbbbccccccccccccc|sometxt
