NB_LINE global variable doesn't return any value

COW_WW — Fri, 17 Jun 2022 16:49:22 GMT

Hello,

I'm trying to use the NB_LINE global variable to get the number of records passed through each link.

It works fine for the first link of tRowGenerator_2, but doesn't work for the second link tMap3 and just prints null.

Am I doing anything wrong?

Thanks

Hi @COW_WW BA ,

but only : ((String)globalMap.get("tMap_3_ERROR_MESSAGE"))

===> you can use : ((Integer)globalMap.get("tLogRow_4_NB_LINE")) to get the number of records (after)

Kind regards,

Thank you. It worked.

Is there any way to check which components have this global variable and which components don't?

@COW_WW BA ,

All components produce one or more globalMap variables that can be used within other components, such as tJava.

you can write component name and then using Ctrl + Space to locate your specific globalMap variable
Otherwise you can simply expand the given component and drag the variables from the outline panel into your code panel

Select as Best if its OK

Kind regards,
