Export failed: Object Communication Channel | BC_Test | Test_File_Sender (DirContext) not found

Hi Experts,

I face one issue when to export deleted objects from Dev server in PI 7.31.

Export failed: Object Communication Channel | BC_Test | Test_File_Sender (DirContext) not found

what I have deleted is sender channel, receiver channel, Integrated Configuration and scenario.

I try to export these 4 objects, it is failed as above issue,

then I try to export sender channel, receiver channel and scenario, it will work,

but when i try to export Integrated Configuration, it will fail as above issue.

do you have any idea for this?

Thanks,

Sep
