Unable to pick data using SFDC sender adapter.

Dear All,

Getting the below error while trying to pick data from SFDC sender channel. We are using SAP PI 7.4 single/java stack.

Error Details;

Receiving Salesforce data failed: [MalformedQueryFault [ApiQueryFault [ApiFault  exceptionCode='MALFORMED_QUERY'
  exceptionMessage='SOQL statements can not be longer than 20000 characters.'
]
  row='-1'
  column='-1'
]

Does anyone know how to resolve this?

Thanks,
