Copying an article doesn't copy Reference Material (MARC-vrbmt)

Hello Experts,

could you please tell me the way to create a new article by copying from an existing article such that the Reference Material number (and other consumption data) is also copied to the new article?

I created a new article from an existing one using the report RWRFMATCOPY but when I check the newly created article in MARC, the field VRBMT is empty.

Appreciate your help.

Regards,

Shakul.
