Hello,
Are we free to modify CDM table constraints to suit our data requirements?
For example, I would like to change length of “Concept_code” field under concept from 50 to 255 as we are creating our custom concepts ?
Might be an elementary question, but just thought of checking with you all as I often see in forum where it is important to maintain the CDM standards as it is to enable reproducibility of our results.
Thanks
Selva
