Datastream has a length limit for expressions.
In Datastream for Excel, it's possible to create longer "User Expressions" that are assigned a code, which can then be used in requests to get around this limit
I am wondering if the same is possible for DSWS, or if there is any other solution for getting around the expression length limit?
Hello @James.Bright1 and @paul.bacon,
Could you please help us answer this DSWS question?
Thank you!

I couldn't find the expression length limit mentioned in the DSWS documents. It only mentions DSWS USER STATS AND LIMITS.
You can share the expression, and then I can try it on Python DatastreamDSWS.

When using the request
ds.get_data(tickers='VOD', fields =['(X(F1FD12)~EB/X(P)~EB)/MAV#(X(F1FD12)~EB/X(P)~EB,3Y)'], kind=0)
the following error is returned:
'Invalid DataType. A datatype should contain between 1 and 45 characters'
There is no error message, however, when using a non-static request (kind=1).
