I want to change the datatype of a column in dataobject which is based on external datasource. Presently the column is having the value as float and when check on the drop down, the available datatypes are string, float and decimal. I want to change it from float to string. But when i change it the Max Size is getting to 0 and it not editable. Its critical to change the datatype, as it is showing the float values in the report and need to have the string format in the report.
Help will be greatly appreciated, as it is critical any suggestions are welcome.
