oleDB Query Builder Error

I'm using the query builder for oleDB object services to bring the Lawson print file and format it in crystal. I used the oleDB object builder for CU201, MM280 etc it worked. But when I use it for RW100 or HR170 I get following error...

An error was returned from the Lawson Application. The error code is [ERROR_GENERATING_XML] The error message is [ An unknown error occurred. Please contact your system admin. ]

OK
