Apply barcode on FTP input files

Hello all

I am very new to PP. Could anyone please help me how to achieve the following requirement where we will consume an actual, well formed pdf as an FTP input. Now, we need to apply barcode on this and the bar code needs to be based on certain text that’s already on the pdf. Can any one please suggest how to achieve this requirement.

Appreciate all the help.

Thanks
