How to implement business rules for connectors

[MV]

did not get any suggestion of previoous posts on the same  

I would like to know how business rules are implemented in UML Modeling using EA. I have set of business rules as requirement type elements. One example is

< 'Transaction Id' must be unique and no transaction with the specified Transaction Id must have already been processed by the system >

I am using Transaction / Instruction kind of appraoch for business process / business activities wherein one transactio includes many instruction.


Now I am creating a mapping diagram between instruciton and data members that will be used for the instruciton. I am simply using a dependency connector between them but here want to asociate my business rules to this connector as follows-

1 - This business rule should be displayed on diagram on the connector
2 - There should be traceability for the busines rule for connector...
