BAI2 Bank Statement: Mapping for "BANK_TRX_NUMBER"

Dear Team,

Below is an extract from the BAI Bank Statement that we receive... If we check for Transaction codes 195 (Receipts lines), data in the Rec ID 88 (continuation to Rec ID 16) has a 16 digit numeric Receipt reference number in Position 1 (highlighted below)

We need to understand how do we map this in the setups of Bank Statement Mapping for statement Type "BAI", such that the loader program populates this 16 digit ref number in the Transaction Number field.

Regards

Rupa
