A document set under an Transfer L/C,  can be closed at any time for several reasons.

For Closing Transfer LC document set, there should be an existing set of documents under a transfer L/C, that is not closed and there may not be any open usance tenors.

The 'Booking procedure' combo box allows you determine how open amounts are to be dealt with when a contract is closed. There are three options to handle:

• 'Reverse Booking (Document Set)': This back posts the open amount in the subcontract. The 'Document Value' and 'Open Amount' fields are set to zero. This is the default option.
• 'Reverse Booking (Doc. Set, L/C)': The open amount is posted back to the L/C value of the main contract. The 'Document Value' and 'Open Amount' fields are set to zero.
• If none of the options in the combo box are selected, the open amount for the contract remains unchanged, That is only the 'Document Value' field is set to zero. For contracts that have already been settled, a relevant message is displayed instead of the combo box.
