Usage List (RFWEKR00)
The usage list lists all forms in a lot and displays for each form number whether it was used for a business transaction, borrowing, guaranty or if it was voided due to destruction, test printing and so on.
Use the report RFWEKR00 to produce this list. Enter the company code, house bank, house bank account ID, payment method and reporting period. To mark a BOE as issued for guaranty, the BOE must be voided using special void reason codes. As previously documented, bills of exchange for guaranty are not created by the system because they do not reflect a payment. The only possibility to track their usage is by voiding them with special void reason codes. These void reasons have to be entered in the selection screen of the report.
Bills of exchange used for borrowing are identified by the special general ledger indicator.

The user creates the void reason code 31 for bills of exchange given as a guaranty to bank1 and the void reason code 32 for bills of exchange given as a guaranty to bank2. Bills of exchange issued for borrowing are posted using the special general ledger indicator
When running the bill of exchange usage list,
‘ u ’ is entered as special general ledger indicator for borrowing and 31-32 are entered as range of void reason codes for bills of exchange handed out as guaranty.
