Derivation Strategy for the Budgetary Ledger 
In order to derive the correct BL accounts from data related to a process in Funds Management, you must create a derivation strategy in Customizing that derives these fields.
See Budgetary Ledger introductory information for prerequisites.
Go to the Implementation Guide for Public Sector Management as follows
Select the source fields to be used for derivation and save your data.
Next, in the same menu path, access the IMG activity Define Derivation Strategy for BL Accounts .
After specifying whether you want to customize the BL for budget postings or commitment/actual postings, create a new step of the type “derivation rule”.
Select the source fields and the target fields for the derivation of BL fields.
Save your data.
Note
If you need to carry out automatic offsetting/deletion, see Special Processing for Multi-Annual Budgeting .
The budgetary ledger has been set up and you can proceed to work with it.
The example below shows the way that the budgetary ledger is normally customized so that the derivation tool is able to derive the correct fields for the BL.
