Multi-Year Budget Execution: Master Data Maintenance 
You require year-independent master data for multi-year budget execution. This means that you can no longer assign a time reference to your master data. You define the validity of a Funds Management account assignment (FM account assignment) using the validity interval in the fund master record. The account assignment element ‘fund’ is obligatory for multi-year budget execution. You can create the fiscal year reference for FM account assignments by using a year-dependent budget structure.
The significance of the fund increases with multi-year budget execution.You define the validity of a budget in the fund master record. It is advisable to make the respective budget identifiable in the fund key using a Budget ID. The budget ID carries out the function of an additional FM account assignment via the fund master record.
Note
Example of budget ID:
The fund 04711 and 04712 are given the budget ID (fund key) 04711-2003 and 04712-2003 for the 2003 budget. For the 2004 budget, corresponding funds are created with budget IDs 04711-2004 and 04712-2004.
Analog to the fund key, you can also assign other FM account assignment elements to a budget by using a budget ID.
Fund and Fund Type
By activating multi-year budget planning, a budget check takes place on the overall budget for all funds and fund types.The budget amount is specified as Overall Budget in IMG activity Define Fund Types .
Master Data Subdivision
It is advisable to use Master Data Subdivision for the budget ID in the master data key. This function makes it easier to maintain master data using a substring and supports reporting via substrings (for example, through the budget ID contained in the substring of the fund).
Year-Dependent Budget Structure
In connection with using the Budget Control System as the budgeting tool, you must maintain a year-dependent budget structure when using a budget structure. Here you define the assignments of posting/budget addresses restricted to the relevant fiscal year. A copy program supports you with carrying out closing operations. For more information, see Budget Structure in BCS .
Note that you must always consider the effects on the affected budget if you make changes to the budget structure of a fiscal year. If for example a funds center is replaced by another funds center, you can transfer the budget or commitment entered in the budget by using program Transfer Budget Data . You can also use the transfer programs intended for closing operations for the year-dependent budget structure or for mid-year transfer postings.
