White Space Issue

I am generating a file in ECC. Record length is 80 Char.

Data is 75 Char and 5 are white spaces. All is good.

The file is picked by PI , PGP encrypted , sent to the bank and original file is archieved.

The Archieved file is good as well with all 5 white spaces.

However the file received at the bank does not have the 5 white spaces.

Could not figure out where the problem is. Any clues would be appretiated.

Rgds,

Pranu
