FMF0, how to find the bad document?

Hello experts,

I could use an advise about FMF0. There is a lot of talk on the forums about that transaction. We noticed, that usually it goes smooth, unless there is a single bad document (i.e. with a lot of operations inside).

In other words - the transaction LOOPS on that very document and if you try to execute it for all the others it is OK, and if you try to execute it for this one bad document it goes forever.

My question is how to discover this bad document, on which FMF0 loops, without debugging?

Last time we discovered it by accident!

Best regards,

Ilian

P.S. I am a basis guy, and I'm sorry if my FI explanations sound a bit odd...
