Hi,
You won't be able to distinguish it from amount type: it will be always 0250. However, you can check VOBELNR field (Payment doc. no) in table FMIFIIT, where all this data is stored and based on which reports are working. If you have different number range for payment document and for other clearing documents, you'll have the required information. If the number range is the same, you'll have to search for additional info in BKPF table, but that would be possible only through a self-made report.
Regards,
Eli
