LLBLGen Pro 2.5 v2.0.50727 ASP.NET 2.0 SQL Server 2008

I'm getting the following error from a field where I have set the sql server data as decimal (4,2). Can anyone tell me why the negative doesn't fit? I would suspect that if this was a positive value it would work. Should I make the the datatype decimal (5,2)?

The precision of value '-18.81' is larger than the precision of the field: '4' and will cause an overflow in the database.

This is due to the Build-in field validation logic. You can disable it or set a correction action for the scale.

Also please check the latest v2.5 runtime lib builds (you posted the .net version , not the buildnr). There were some issues with the validation checking in earlier builds.
