Hello Pankaj,
Well it is since version 8.5.0.4 that 128 fields are available to CMOD :-D
Why? Because you have no idea how creative the customers are :-D they want to store lots of data in the fields! We try to cool them down :-) and not add things like birthday!!!
During a migration, were the business couldn't decide what to keep and what not, and they had new fields for their new system, so added them together with the old data... meaning that had more than 32 fields, something like 34 or 36.
Sincerely yours,
Alessandro
