User Defined Object Default Form -> Can't add record

Hi,

I have created a user defined object on a Master Data Table with acccompanying Rows table.

For some reason I can't get any records in the Master table. SBO claims the operation (save) was succesfull however the table remains empty and the line I entered gets cleared!

I'm running SBO2005ASP01PL07 so I don't think I'm missing any updates.

Anyone have an idea as to what''s wrong?

Regards,

Ivo Vink
