Create security profile for a document template in SAP Sourcing

Hi Gurus,

In my current SAP Sourcing system we have created 3 Master Agreement Document Types

For Example : Template 1> Standard Agreement

                      Template 2> Standard Large Agreement for more than 1000 line items

                      Template 3> Hierarchical Agreement

I have got a requirement to create a security profile in SAP Sourcing application to restrict the users to view or create Master Agreements templates not assigned to them.

i.e. If the User is assigned to create only a master agreement from template 1 (Standard Agreement) he should not be able to view or create MAs from the remaining 2 Templates.

I have tried to create security profile but there is no option/drill down for Business Document Template under Access Right.

Please share your thoughts on this.
