How to get ID by generating PDF document!!!

Question

Hi all, 
 
 Actually, by using Dynamic DOCX Template I am generating a PDF. 
 Now I want that PDF ID to save in a process model. 
 
 I tried by creating a process variable of type number integer and tried saving the generated document from the plugin into the process variable and didn't work out!! 
 
 Can someone suggest me how can I achieve this. 
 
 Thanks In Advance.

Make sure the smart service is not giving any errors. There are cases when the node will complete without the visible error but the out variable "Error" will tell you a different story. Store the error in some variable to check if everything is fine. 
 Try changing the type of that variable from int to doc. 
 Make sure no other nodes are overriding your variable and setting it back to null.

Did you try creating a pv of type Document instead?

The "Document" type PV already (actually) contains the document ID - Appian just shows us the document's name to be "user friendly" - but this can be cast to INTEGER type at any time we need - you could just use a subsequent script task to save that PV directly into an INTEGER type variable and you'd have it. 
 But yes if you want/need to save the ID directly at save time, all you need to do is add an extra node output entry, just below the place you (already) have it configured to save into pv!newDocumentCreatedPDF:

Did you try doing document(pv!newPDF, "documentId")?
