Friends, my issue is such. A cancelled down payment request (S1) billing document is generated without error. If you look at the corresponding accounting document it is totally blank - no lines. The customer account still shows the original postings (no reversal is posted). However SD thinks it is cancelled and will not allow another vf11 of the original DP request.
I am unsure if an issue with SD or FI-CA.
This happens only very infrequently and I cannot reproduce the issue in test but it has been seen in production occassionally.
We have only found one note that looked relevant at all but it is not the solution to the issue.
Please advise if ever seen a blank accounting document related to a s1 SD doc for a down payment request.
