E1PRTOB segment lacking into AUDIT IDoc

Hi to all,

I have a problem with AUDIT. When I execute the RBDSTATE function module to perform ale Audit, the Audit IDoc is sent to XI but without the E1PRTOB segment into payload (I've seen this into SXI_MONITOR transaction). However, I see the segment into the WE02 transaction in the AUdit sender system, and I've also controlled the metadata into XI IDX2 transaction and they are ok! What is the problem?

Thanks!
