Using the USING SYNONYMS Parameter
The USING SYNONYMS parameter controls the queries of account synonyms during import processing. This parameter is also related to the S_ORG_SYN table. When set to FALSE, this parameter saves processing time because queries that look up synonyms are not used. The default setting is TRUE. You should only set this parameter to FALSE when account synonyms are not needed.
