Users are encouraged to define the link module to use for linking requirements, otherwise the default link module will be used.
DOORS provides a feature, called Linkset pairings, that allow users to control what links can be created by defining the source module and the target module as a pair together with the link module to use. Please refer to DOORS user manual for more details.
To add linkset pairings:
Ensure that there is an entry showing your target module and your link module.
