How can I get a list of parameter for "fields" that can be downloaded historically for a specific item?
For example in the above, if I enter ['PH','PL','PO','PI'] to "fields", then I would get the respective time-series data for 'AMXTPNJ'.
So, is there a way to find all available parameters ('PH', 'PL', 'PO', 'PI' in the above example) that can be entered into "fields" for each of non-static item?
I don't think that we can do this in the Datastream DSWS. The data types or fields must be known before using the Datastream DSWS.
You can use DFO in the excel or visit this website to find datatypes or fields.
