All Interfaces are not working in XI/PI
We have around 15 interfaces in our landscape (PI 7.0), out of which 5 are outbound from SAP, and remaining are inbound to SAP.( eg: Cond_A, EAN, DEBMAS, CREMAS, WPUWBW,WPUBON.etc......).
Earlier all are working fine, all of a sudden, no interface is working. I have checked all the configurations. like, RFC Connections, Ports, Partner Profiles,
all are maintained properly and working fine.
All RFCs are maintained properly both in XI and R/3. Ports are pointing to correct target system. and all idoc types are maintained under partner profiles.
When we try to trigger an idoc from R/3 it's not getting generated, we're getting a waring message as " Idoc is saved and could not be processed".
Similarly, when we post a flat file in FTP, it's picked up by PI Communication channel, i'm seeing Chequered flag in SXMB_MONI, and also successfull message in message monitoring, but it's not updating to SAP R/3.
I tried to restart ths server,and did the full cache refresh. but no luck.
Please suggest your valuable inputs to resolve this issue.
Thanks in advance.
