Process Single RIB Rule 
A RIB rule defines the processing path used to generate an expenditure budget in the Revenues Increasing the Budget process. This enables you to specify the exact conditions under which you permit that revenues may be used to increase the budget.
Each RIB rule is based either on a RIB object or on a revenue cover group, each bundling a set of contributing revenue FM account assignments for the calculation of the available revenues, and linking such a group of contributing FM account assignments to a set of receiving expenditure budget addresses. Furthermore, the RIB rule defines how the budget amount is calculated for increasing the budget on the receiving budget addresses.
You can process single RIB rules in the transaction FMRBRULE:
You can review existing RIB rules by specifying the RIB object or the revenue cover group a RIB rule has been based on, or by selecting a posting or budget address contributing to a RIB object or revenue cover group for which a RIB rule already exists.
You can also create single RIB rules. A new RIB rule can be entered by selecting a posting or budget address, from which a new RIB object is derived using the derivation strategy for RIB objects defined in FM Customizing; or by specifying a revenue cover group for which a new RIB rule is to be created.
When creating a new RIB rule, you must assign an activation status, a filter profile (for selecting the kind of revenues for the RIB procedure), and a calculation formula. With the help of the calculation formula, you stipulate whether you want to work with lower or upper limits for the RIB procedure.
You must specify the RIB procedure (distribution procedure or call procedure) to be used. If you choose distribution procedure, then you have the option of assigning a surplus budget address as the receiver of the revenues exceeding the upper limit (the “surplus amount”), as defined by the calculation formula. You must assign at least one receiving expenditure budget address which receives the expenditure from the distribution procedure, but you can also specify several receiving expenditure budget addresses, including the percentages for distributing the budget increase among them. Please note that the percentages must total 100%.
If you choose call procedure for a new RIB rule, you must assign the RIB rule to an automatic cover group, and the definition for using the surplus amount becomes unavailable. A single RIB rule cannot be assigned to more than one automatic cover group in any one availability control (AVC) ledger . RIB rules with call procedure provide additional consumable budget for availability control checks for automatic cover groups without increasing the expenditure budget. That is, the budget is only virtually increased for the purposes of availability control in the framework of automatic cover eligibility.
Before you can use this function, you must carry out the following Customizing activities under :
Define Derivation Strategy for RIB Objects
Maintain Calculation Formulas for RIB
Maintain Derivation Strategy for Rule Generation
If you want to use Budget Memos , you must activate them in the first Customizing activity in this node.
If you want to use RIB rules with revenue cover groups or with call procedure, then you must activate cover eligibility . You have to activate RIB call procedure in Customizing activity Activate Cover Eligibility under
In the SAP Easy Access menu, choose Public Sector Management -> Funds Management -> Master Data -> Use of Account Assignment Elements -> Budget Control System -> Revenues Increasing the Budget -> Rules for Revenues Increasing the Budget -> Change (transaction FMRBRULE)
Enter the fiscal year and the budget category to be used for revenues increasing the budget (RIB ledger).
If you want to review an existing RIB rule, select the corresponding tab for RIB objects or revenue cover groups and use the search function. You can also enter the full account assignment for the RIB object which a RIB rule is already assigned to, select the tab for budget addresses or posting addresses and enter an address that is linked to a RIB object or revenue cover group (or you can enter a revenue cover group in the revenue cover group tab). After making your selection, click the icon Display Rule , if you want to see the individual RIB rule information, or select Change Rule , if you want to change the RIB rule.
If you want to create a new RIB rule, select the corresponding tab for budget addresses or posting addresses and enter the revenue account assignment the new RIB object is to be derived from, to which a new RIB rule will be assigned. If you work with revenue cover groups, you can also choose the tab for revenue cover groups and enter a revenue cover group for which no RIB rule has yet been defined. Then click on Create New Rule or Create New Rule Using Derivation Strategy .
Note
The latter function can only be used if you have maintained a derivation strategy in the IMG activity Define Derivation Strategy for Rule Generation . In this case you will branch to the same screen as for creating a new RIB rule, but it already contains the settings as assigned by the derivation strategy for the RIB rule generation. You can change these settings here. When you are done, save the new rule.
If you want to assign a revenue budget address to a RIB object, choose the tab for budget addresses and enter the desired, and as yet unassigned, budget address.
Click on the icon Assign Address to RIB Object .
When you review an existing RIB rule or when you create a new RIB rule, the program branches to a detail screen after you select the desired function. On the detail screen, you see the RIB object or revenue cover group and all contributing revenue FM account assignments on the left-hand side. Definitions for calculating the RIB amount and the assignment of the receiving expenditure budget addresses or automatic cover groups (if you use RIB call procedure) are maintained on the right-hand side.
Here you can also insert, delete and copy receiving budget addresses or automatic cover groups by using the corresponding buttons.
For further information, see Detail Screen: Single RIB Rule .
Note
If you change an existing RIB rule, or if you create a new RIB rule for FM account assignments, for which application data such as revenue documents or budget data already exists, it is recommended that you reinitialize the RIB ledger after saving the new or changed RIB rule.
