SAP Transaction Code FBL1N
The FBL1N is a standard report in SAP for finding the balances on SAP vendors. The report can be run for an individual vendor, a group of individual vendors, a range of vendors, or including some vendors and excluding other vendors.
A variant can be run to to saved reports that will be used on a regular basis. Once a report is run, the report layout can be changed and the report can be filtered using the standard SAP buttons.
The report can be exported to Excel very easily for data manipulation purposes.
The general document types that will be used in an FBL1N are KN and KM, for vendor invoices and manual checks. It will also use the ZP, for vendor payable.
Vendors are created and edited using FK01 and FK02, respectively.
