AXAPTA - Empty compound statement warning

Axapta generates this warning when compiling. To avoid this warning empty blocks may be remove. But when issue Try/Catch block you can't do this. Well, what do you do?

catch (Exception::Error)
{

 exceptionTextFallThrough();

}

I found this function from a  blog, it does nothing except supress warning.

AXAPTA Set empty date and datetime values

for Datetime values:

myDateTime=DateTimeUtil::minValue();

for Date values:
myDate =global::dateNull();

AXAPTA empty InventDimId

InventDimId is a mandatory field for some tables. If you don't use it, you can left it blank:

SMAServiceBOMTable.InventDimId  = InventDim::inventDimIdBlank();
