Generating GM-GTE RIB Rules 
You can automatically generate a new RIB rule using transaction GMRBGENMD. You define a RIB rule by specifying the revenue and expenditure GM account assignments to be used in the RIB process. Each RIB rule is assigned to a RIB object, which aggregates revenues from revenue posting addresses. The procedure applied for assigning RIB objects to their contributing posting addresses is illustrated below:

To generate new RIB rules, you must specify the set of addresses on which the generation is based. You can choose between posting/budget addresses, from which new RIB objects will be derived, and you can also decide to select addresses from application data (revenue documents).

Only one receiving budget address can be assigned for each RIB rule generated. This is the budget address which will receive the full RIB amount calculated according to the new RIB rule. If you need to distribute this amount to several budget addresses, you must specify them, together with the desired percentages, in the transaction GMBRBRULE.
In order to have RIB rules generated automatically, you have to set up a derivation strategy for the generation of RIB rules in GM Customizing.
