Thank you for reaching out to us.

The "TR.CommonName" field may be invalid for deal screeners.

The following code works fine.

#start_date
start_date="20200101"
 
#end_date
end_date="20200108"
 
#universe
universe=f'SCREEN(U(IN(DEALS)/*UNV:DEALSMNA*/), BETWEEN(TR.MnAAnnDate,{start_date},{end_date})/*dt:Date*/, CURN=USD)'


#fields
fields=["TR.MnAAnnDate","TR.MnATarget","TR.MnAAcquiror"]
 
#rd.get_data
df_i=rd.get_data(
    universe=universe,
    fields=fields, 
    #parameters=None,
    #use_field_names_in_headers=None,
    )
 
df_i

You can use the Deal Screener app to list all available fields.
