Hi Pierre,
This is right, but as per example I provided earlier, multiple configuration is manageable with $G_FILE_LANDSCAPE & $G_FILE_LOCATION. This will enhance execution of your dataflows that have flat files as a source.
print($G_LANDSCAPE); $G_LANDSCAPE = current_system_configuration(); print($G_LANDSCAPE);
if ($G_LANDSCAPE = 'DEV') $G_FILE_LOCATION = 'C:/DEV/Flat_Files';
else $G_FILE_LOCATION = 'C:/TEST/Flat_Files';
print($G_FILE_LOCATION);
When you need a lookup into your dataflow, then the lkp file is taken from the datastore which you mention in the syntax. I think the only way to separate them is have 2 different datastores and manually change before run, which is not too elegant.
But now HCI can also be a multi tier system, so why not enhance your landscape and have just one system configuration per landscape?
Cheers
