I have the following problem:
sometimes an idoc fired from SAP (not through WE19) does not reach XI (I cannot see it in SXI_MONITOR). I've checked the following facts:
1. SAP R/3 status of the idoc is 03 (direction outbound).
2. SM58 produces no result.
3. IDX5 produces no result for that idoc.
4. 99,9% idocs of the same type fired in the same day work fine.
Resending manually the same Idoc using WE19 gives no problem and the idoc reaches XI.
Thanks a lot,
