Transformation error when activating BUS_UNIT_GL_SYNC between FSCM and ELM’

We are currently on PT8.59.04.

We have activated the BUS_UNIT_GL_SYNC Service Operation in FSCM and ELM with routings where the sender node is FSCM and the receiver node is ELM.

When this service operation goes to the ELM's Asynchronous Service Monitor (Oper Instance queue), it is failing with the error below. How do we resolve this issue?

`No transformation found in the IA transformation schema for 0000, message BUS_UNIT_GL_SYNC. (18137,202)

The Default Version is the only version active for the BUS_UNIT_GL_SYNC in ELM.

We get the same error message whenever we us the HMTF_TR or HMTF_TR_IA transformation program. The External Alias Name matches the External Alias Name for the BUS_UNIT_GL_SYNC service operation in FSCM.
