CECN0127E (0x010C007F) CECN0127E You cannot add a replication mapping for the object obj-name to the subscription subscription-name1 because subscription subscription-name2 already has a replication mapping for this object and both subscriptions specify target URL target-URL.

Explanation
The attempt to add a replication mapping for the object failed because another subscription in the source server already contains the object. A source server cannot contain multiple subscriptions that replicate the same object to the same target server to prevent replication errors.

User response
Verify whether the replication mapping for the object is active in the other subscription.  If the object is parked, either activate it and replicate the object in subscription-name2 or delete the existing replication mapping and retry the operation to add the object to subscription-name1 again.
