Automatic Budget Processing 
The US Government Standard General Ledger (SGL) defines the accounting transactions that federal agencies must use. Many of the specified transactions must, in turn, automatically generate a budget transaction. The Federal Government solution includes an Automatic Budget Postings (ABP) feature developed to satisfy this requirement.
ABP automatically posts budget transactions in the Budget Control System (BCS). The generated budget transactions can be either budget transfers or budget entry transactions.
The ABP feature cannot be used with the Former Budgetary Ledger. You must configure and use the new Budgetary Ledger to use the feature. Posting and document dates flow into the budget documents from the triggering transactions.
Derivation rules are used to specify which transactions are relevant for ABP (for example, sales orders, customer invoices, incoming payments) and what the values should be for the sender and receiver lines of the budget transaction. You can specify default values for fields on the budget document header using a configuration screen. If default header values do not satisfy your requirements, you can use a Business Add-In (BAdI) to override the values.
Before using this
function, you must first customize and activate the Budget Control System
(BCS). For details, read the
Budget Control
System documentation.
Having configured and activated BCS, you must carry out the customizing steps described below before you can use ABP. To access them, go to the Implementation Guide (IMG) and choose Public Sector Management ® Functions for the US Federal Government ® Automated Budget Postings.
· Activate Automatic Budget Postings
In this step, you enter the FM area(s) where you want to use ABP and check the activation flag.
· Define Budget Entry Document Header Defaults
ABP creates budget entry documents. Use this step to configure the defaults entered in the header of those documents. You do this per FM area and document type.
· Maintain Derivation Strategy for Automatic Budget Postings
Generation of budget entry documents in the BCS is triggered according to a derivation strategy you establish here.
The IMG documentation for this step contains detailed instructions on what you must do.
· Business Add-Ins
¡ BAdI: Override Default Budget Entry Document Header Values
Having defined budget entry document header defaults in the step mentioned above, you can use this BAdI to override some of them – for example, to change the budget document type.
