IDOC in 03 staus but not coming to PI system..

Hi Experts,

I am working on IDOC to IDOC scenario.All of the IDOCs are in 03 status in R/3 system but some of the IDOCs are not coming to PI system.I checked SM58 also but its fine.

Should it be in 12 staus?

Is it possible that IDOC in status 03 can reach to the target system?

Please reply it asap.Its urgent.

Regards,

Vikram
