Hello. I was hoping someone would know the answer to this one. I am running the following query:
response = ld.get_history(start = min_date, universe= security,  end = max_date,                                fields= price_fields,  adjustments = adjustment_factor,)
It seems to work for the companies in my sample, but I get an error regarding the following RIC: 
ZALG.DE
I am having the same issue with the Excel Add-in. 
The error I am getting is 
The universe does not support the following fields: [TRDPRC_1].
Any help will be welcome. 
PS: I am new to Infinitiv.
