Hi,
In universe parameters, there is an option as 'Limit size of long object to' option.
Can you check for the same in business layer parameters?
As far as I am aware the limit is 65000 characters.
Can you check the length of the values in the column in case It is a long text column?
If it is less than 65000 then you can search for the option, try setting the desired value and check.
Or simply uncheck that option and check.
Regards,
Yuvraj
