Problem sending Idoc ECC->PI

Hi Experts!!

I create a RFC that generate own designed Idocs to SAP PI.

After execute I can seeo the Idocs in WE02 in the correct status 03 but I cant see it in SAP PI (The status log is 01->30->03 as all the idocs that i generate before). If I send it using WE19 or BD87 It works fine.

I Checked SM58, SMQ2, SMQ1 in ECC and in SAP PI:  No errors found.

I reimported the Idoc (IDX2): still the problem.

No message in SXMB_MONI when generate idocs with the RFC.

Thanks in advance!
