We have a scenario :
a livecycle process uses ddx to attach pdf (lets call it child pdf) to the parent pdf. The parent pdf is then apply usage rights.
At the end of the process it output a the parent pdf with the child pdf attached to it.
What is causing a problem now is that the child pdf (which used to have usage rights applied) have now got usage right removed.
We have proved that it works if done manually using acrobat, but somehow its not working in an orchestration using ddx.
Thanks its been sorted, there is a checkbox in apply usage rights activity called embedded file attachments, tick that and it will apply usage rights to the attachments in the parent pdf.
You should mark this answer as correct.
Can you please share the orchestration and the pdfs and ddx used for reproducing this issue.
