-- HL7 business document check doesn't raise any error
-- map using HL7 document raises an error: Cannot convert boolean field (Y) from external to internal format

* issue is fixed by incoming Mapping Services 2.4.0_SP8 for new HL7 imported business documents
For existing business documents/containers:
-open the HL7 business document
-search boolean business document fields
-replace values Y and N by true and false
