Hello:
I am trying to get the values of ‘AW_*’ system variables that a custom transfer uses as a parameter, but am only getting a null value.
For example: In my script, I have
get_env(‘AW_FILE_NAME’)
Wanted to see if someone has tried the same and if this is something that BODI does not pull via get_env? a get_env(‘PATH’) works just fine.
Help,
Sowmya

Remember that jobserver, jobs and dataflows a processes of its own. So it depends on how you set the environment variable and where. Different places, different visibility.

Thanks Werner for your response!
Here’s the structure of my Job
Level 1: Job
Level 2: DataFlow
Level 3: R/3 Dataflow
Level 2: Script with the get_env(‘AW_FILE_NAME’)
The R/3 Dataflow has a Custom Transfer Method and contains the use of AW_FILE_NAME. The Data Transport Object in the R/3 Dataflow has a “filename” entry and I believe AW_FILE_NAME gets the value of “filename”. I say that because, when I run the Job, the “filename” value gets printed in the trace logs when it hits the Custom Transfer program execution.
Are you saying that these DI System variables (AW_FILE_NAME, AW_ROOT_DIR) loose visibility once the execution comes out of R/3 Dataflow? Any workaround ideas on how I can get hold of the values?
