Disassemble PDF document

Hello,

Trying to disassemble PDF document contains 100pages to individual pages.

Using Workbench ES4 to create process, this is DDX.

<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<DDXProcessorSetting name="checkpoint" value="4000"/>
<PDFsFromBookmarks prefix="A">
<PDF source="doc1"/>
</PDFsFromBookmarks>
<?ddx-source-hint name="doc1"?>
</DDX>

Added variable IN and OUT as well as assembler result.

When i test run my result document shows empty.

Out variable is mapped to "/process_data/KGL_WaterMark_Result/object/documents"

Created watch folder and checked, document not splitting up, same combined coming to result folder.
