Hi Akshay Gary,
Business processes in Cash and Bank Management are as follows:

The business processes in the cash and bank management include:
- Deposit bank funds
- Reconcile bank accounts
- Transfer bank funds
- Manage letters of credit
- Manage letters of guarantee
Processes in Budgeting:

You can use Budgeting to set up, create, and view budgets. Budgeting can include budget control, which you can use to monitor the budget funds that are available for planned and actual purchases and expenditures. You can create budget register entries for the original budget, budget transfers, and budget revisions. You can also create budget register entries for encumbrances and pre-encumbrances for purchases and planned expenditures. Budget register entries can be created automatically when budgets are transferred to the general ledger from other modules, such as Project management and accounting or Fixed assets.
You can determine which financial dimensions from the chart of accounts are available for basic budgeting and budget control. When you configure budget control, you define budget intervals, budget cycle time spans, budget thresholds, budget managers, budget groups, and the calculation that is used to check for available budget funds. The available budget funds can be verified when source documents and accounting journals are entered. You can view the status and history of budget register entries, budget control statistics, actual versus budgeted amounts, budget details, and budget funds available.
Processes in General Ledger Module:

The other processes that you can perform in General ledger:
- Jouralizing
- Process closing transactions
- Allocate transactions
- Maintain ledger accounts- Close transactions
- Allocate costs and income
- Forecast cash flow and currency requirements
- Eliminate transactions
- Revalue currency amounts- Convert accounting currency

Processes in Fixed Asset Module:

You can set up and enter acquisition information for fixed assets, and then manage the assets by depreciating them and setting a capitalization threshold to determine depreciation. You can calculate adjustments to the fixed assets, and also dispose of them. When you use General ledger together with Fixed assets, you can view the current value of all fixed assets.
