3472386 - Error Message “Multiple Business Instances Detected for Logical System XXXCLN123” While Replicating Data to C4C

Symptom

You are replicating data to C4C and you notice the error message "Multiple business instances detected for logical system XXXCLN123" on the web service message monitoring tool.

XXXCLN123 represents the logical system ID.

Environment

SAP Cloud for Customer

Reproducing the Issue

  1. Go to the Administrator work center.
  2. Go to the General Setting work center view.
  3. Open the Web Service Message Monitoring under System Administration.
  4. Select query Erroneous.
  5. Search for message ID with error: "Multiple business instances detected for logical system D10CLNT100".

Cause

The message is failing because there are two active Communication Arrangements for the incoming message, such as "Material Replication from SAP Business Suite".

According to the standard design, the logical system must be unique. Otherwise, the system does not recognize which communication system should create the ID mapping.

 

Resolution

To rectify this issue, you need to deactivate the duplicate Communication Arrangements.
