Hi, In our Application, through a job scheduler we push the Unsigned PDF output to an SFTP folder, and then Batch file will be executed to move the file from Unsigned to Signed folder with DSC signed in it. We are generating Digital invoice Signature by plugging the DSC Dongle and entering the Dongle password. But sometimes we are receiving Blank invoice attachment without any Invoice data fetched in it. Kindly let us know if there is any solution to arrive without receiving a Blank Invoice.
