Working with Several Budget Categories 
With the multiple budget entry tool (transaction FMPEP), the Budget Control System contains a second alternative budgeting tool to the Budgeting Workbench. Specifically, you can use this tool for the following purposes:
in order to plan your budget using more than one budget category
in order to plan your budget for more than one fiscal year
in order to directly update the database if necessary, or work only with delta values
The multiple budget entry transaction is fully integrated with Public Sector Funds Management.
BCS must be configured and running. See the link at the bottom for further prerequisites.
Transaction FMPEP provides the following features:
You can enter budget (using only the budget processes ENTER, SUPPLEMENT and RETURN) for the payment budget, the commitment budget, and the financial budget at the same time.

Entering several budget categories simultaneously enables budget planners to obtain an overview of the budget of any FM account assignment (FMAA), no matter what budget category it was planned for.
This means that you only enter an account assignment once , since it is valid for all budget categories. This prevents errors that might occur if you cannot enter budget values for several budget categories at the same time.
Provided Customizing has been correctly carried out, you can work with different fiscal years in one screen.
Provided this is specified in Customizing, you can work with the “additive mode”, which means that you decide whether you want to directly update the database values, or simply enter the delta values.If you update the database values (additive mode “off”), you will see the annual budget values in the entry columns.
No matter whether the additive mode is on or off, when you post your budget data, you always generate an entry document , in which the delta values are posted using the distribution key specified in Customizing and displayed in this transaction.
In Transaction FMPEP, you enter the FM account assignment elements for your budget categories. You can enter them manually or carry out a database search for the elements in question. Then you can carry out budgeting as in the Budgeting Workbench. The following functions are supported:
You can enter additional lines in the SAP List Viewer section.
The automatic release function is also supported.
You can enter a budget text for this budget (menu Goto →Budget Text )
See the link below for further procedures on how to work with this transaction.
