Unable to access each custom property in a document

I am trying to copy each custom property from source document to destination document in PDF. But there is no direct method to do soo. Please help me on this.

@yagnyasridhar,
You can store and retrieve custom properties from a PDF document. Please refer to this help topic: Storing and retrieving custom properties using Meta info. However, if this does not help, then kindly send us your PDF documents, we will investigate and share our findings with you.
