Can we call DMS Attachment Function from ECC to SRM

Hello All,

We have the below requirement.

   a)  User Create the RFx(SRM) from PR(ECC) vai CPPR functionality.Now during creation we need to copy the DIR Links of  PR to RFx .

  b) In SRM RFx ,at item level we need to place a button called "DIR" ,when user click on the button , we need to bring the   DMS Attachment POP UP from ECC to SRM , where user can add new DIR or Delete the DIR.

           Can we do the requirement  "b" ? , is there way we can call the "DMS Attachment Function"  from SRM? . Kindly share your thoughts.

Thanks

Channa.
