The 'Liability Adjustment' is to adjust the internal entries on the Liability Panel for the Transfer L/C contracts.  The Booking amount field changes the Liability amount without creation of new Amendment transaction.

When a negative amount is entered the current liability will be reduced by the amount and in case of positive amount there will be an increase in the current liability. The amount of the contract is not changed by an internal adjustment. 

For Usance/Acceptance LC's, if there is a request to extend the maturity of the LC and if this transaction was created from an auto-registration of Common Messages, the Maturity Date of the Usance contract could be changed in the 'Liability' panel.

To do Liability Adjustment under Transfer L/C, BTTTEN transaction is used.

Select it from the menu item[Export Products ->Transfer L/C -> Other Transfer Documents -> Liability Adjustment]. 

(Users can directly start this transaction by clicking the  (Launch transaction ) available in the Panel headline without having to select the relevant menu) 

When you have made your changes, click on the ( )  Save function to save all the the data entered in the transaction to the database.
