Algorithm for the PDF data transmission:
Outbound:
-
Read the PDF file into an internal table ( via
program ) – Binary form
-
Convert Binary table data into Xstring
-
Encode Xsting Data into Base64 format
-
Create an Idoc with the Base 64 format
Inbound:
-
Receive/read the idoc
-
Decode Base64 data into Xstring
-
Xstring into to Binary
-
Binary file store in directory
-
Create pdf file from the directory
Very simple and sample Code attached :
