Update properties in BP Master Data with DTW

Hi all,

I've a problem using DTW in SAP BO 2005 A:

I'm trying to update groups in properties, related to BP's in BP Master Data.

I'm using the template oBusinessPartners/BusinessPartners.txt with fields:

RecordKey, CardCode, Property8 (that is the one I want to update).

I populated Property8 with Y but DTW gives me back following error:

Invalid Item Name 'Y' in Enum 'BoYesNoEnum'65171

Is it a type of field problem?

Thanks in advance
