Donna,

Welcome to the Sage 50 family. When you enter into the "Account Register" the cash account at the top of the page represents one of your checking accounts. If you are depositing money into the cash account drawn from the line of credit, you only have to do the deposit.

Enter the transaction as a general ledger journal entry showing the debit going to cash and the credit against the line of credit general ledger 

account. Now the entry will show up in the Register as a Gen Jrnl

Let me try to clarify how Sage 50 works. If you do a general ledger journal entry you can post to any gl account. If the debit or credit is a cash account the entry will show up in the account register and the bank account to reconcile. In this example the general ledger is posting the increase to cash and the increase to the line of credit.  If you want to show the trail of payments made on the line of credit you can set up a vendor ID for the LOC and post the payments as a payment, write checks or a payment under account register because those entries require a vendor ID.  Now when you look at the vendor ID you can see all of the loc payments from any bank account that you used to pay back the loc.
