There are some OSS note available in service market place, but those are talking about function module not transaction.

Have you tried to find something by debugging ?

I can find 3 notes: 1996773, 2147289, 2149895    

If none of them can solve your issue then you need to open an incident at SAP support yourself to get a solution - in case you did nothing unexpected.

error messages have in general a meaning and do not just serve as a root cause which needs to be fixed by program corrections, there might also be wrong settings in your own master data.
