Hi,

You can add the necessary conditions in the expression editor in the output section of the tMap and can pass the values to output file. If you want the data to be written in same file, you can do it by selecting append option in tfileoutputexcel.

Hello toumakabibiche,

may I recommend using customvalues1.customized_type = 'Project' as a where condition in your input SQL of the custom_values component instead of using it in tMap (as a filter or join condition)?

I suggest not connecting customvalues1.custom_field_id and customvalues1.value directly to the output pane (to "client" and "demande"). Put them in the Var pane first, and from there connect them to the output.

Concerning the NullpointerException: Please insert a query for null value in your Var.var1 expression, in general for all the fields from customvalues1 that you connected to the Var pane. For example: customvalues1.custom_field_id == null ? 0 : customvalues1.custom_field_id and name this field notnull_custom_field_id. You can then continue to build your other expressions in the Var pane using this notnull_custom_field_id (instead of the custom_field_id directly from costumvalues1).

Best regards,

Thomas
