Hi Ahmed
did you use the program via IMG to create the rule? I think that's program GRFNMW_DEV_RULES
IMG Path: Governance, Risk and Compliance > Access Control > Workflow for Access Control > Define Workflow-Related MSMP Rules
When you create via the program, you can select to generate the decision table.

Clik here to view.
Choose the Header box - a pop up will appear and you can select request type
Once it has been created, you can then go into BRF+ and the decision table will exist for you to maintain your scenarios (the number values that you configured under Maintain Request Type that represent the NEW, CHANGE and TERMINATE). Please note that if you have other values you must have a mapping for each. I recommend you have at least one scenario for catch all (i.e. is not = NEW, CHANGE AND TERMINATE). this is safety in case someone creates another request type and doesn't update the brfplus mappings.
Have a look at the following SCN threads where I've given advise on the BRF+ steps
Error while creating BRF+ initiator Rule
The first link is what you are trying to do but they had an error. The second link is a similar scenario but I gave steps on what to do in MSMP
