The error "ORA-00913: too many values" means that the source table has more fields than the destination table.  In this case, table INTERACTIONS_12721561 was a temp table created before the sync was install, and was missing the BBECSYNC field (found in the INTERACTIONS table).  So when records from INTERACTIONS were trying to copy to INTERACTIONS_12721561, Oracle found it had no place to put the data from the missing field.

To fix this issue, compare the columns/fields of the 2 tables and add the missing one(s).  Here is an example of updating a table with a new field:
 
ALTER TABLE INTERACTIONS_12721561
ADD     BBECSYNC    VARCHAR2(1);
