Process not reaching orchestration

Hi

I’ve got a simple filedrop message scenario. File dropped in, receive port has custom pipeline, disassembling flatfile, message enters orchestration and does some stuff (more file drops).

When I start the process by dropping my file into the receive location, the file is picked up and goes through the custom receive pipeline successfully but then just stops. In HAT, it just says the custom pipeline part was completed and there is no mention of the orchestration anywhere, no error messages or anything.

Everything is deployed, the orchestration is bound to the respective ports etc, everything is enlisted and started, the biztalk host instance is running etc.

Does anyone have any initial thoughts?

Cheers
