Hi Folks:

My Data is being passed through the Aggregator stage and is being aggregated. I am trying to suppress this warning message which is coming from the Agg Stage. Though it mentions to use the Modify stage to handle null. I had no luck doing so. Plus I am not quite familiar with the modify stage. Its syntax is not that clear. I guess I can use the Message Handler but would like to get rid of it without using the MSG Handler.

When binding output interface field "AGG_FIELD" to field "AGG_FIELD": Converting a nullable source to a non-nullable result;
a fatal runtime error could occur; use the modify operator to
specify a value to which the null should be converted.

I have the this column value set to "NO" for Nullable

If someone can provide an example of the syntax for using the Modify to handle null, this would be greatly appreciated. The column AGG_FIELD is of type Decimal.

Thanks,

Specification: OutputColumn = handle_null(InputColumn, newvalue)

Thanks for the feedback, but your suggestion did not work. I am still getting the same warning message

In the modify stage, I coded:

Specification: AGG_FIELD=handle_null(AGG_FIELD,0)
Specification: NOWARN

And I got:

agg_value: When checking operator: When binding output interface field "AGG_FIELD" to field "AGG_FIELD": Converting a nullable source to a non-nullable result;
a fatal runtime error could occur; use the modify operator to
specify a value to which the null should be converted. [api/interface_rep.C:1384]

You will get the warning irrespective - it's metadata-driven.

Create a local message handler to suppress it.

I got rid of the warning messages and here is how I did it. I decided to change the AGG_FIELD metadata to "YES" for Nullable. Then in a transformer I used the following code:

if IsNull(out_from_Ag.AGG_FIELD) then SetNull() else DecimalToDecimal(out_from_Ag.AGG_FIELD,'round_inf')

I am doing some rounding also.

Transformer, robots in disguise...

thanks

We are using Source as SQL Server and Target as DB2 , when i migrating in source side IsRecurring data type is BIT and Target IsRecurring data type is SmallInt.
