Hi Mariana,
The LCR is kind of bill of exchange. The parameters are similar RIBA in Italy.
Below, you can find as I have defined the LCR magnètique:
After, you have to customize:
Bank Accounting-->Business Transactions-->Bill of Exchange Transactions-->Bill of Exchange Receivable-->Present Bill of Exchange Receivable at Bank
I hope to clear for you.
Good work 
Kind Regards
Giampaolo
