No service for system SAP***, client 001 in Integration Directory

Hi,

We are doing a File to IDOC scenario.

The file is picked up and the idoc is getting generated in XI but this idoc is failing at XI outbound with the following SM58 error:

No service for system SAPABC, client 001 in Integration Directory

where ABC is my XI system ID.

I have searched in sdn and tried all the possible solutions given in the previous blogs with same subject but not able to resolve this error.

Any help will be greatly appreciated.

thanks in advance
