#DATATYPE ERROR in WebI

#DATATYPE ERROR


Environment: WebI BO XI R3.1 SP 4 

You got thi error when you are using a wrong data type . 
For example if  your data is numerical but it is throwing char or date then Business Objects will  expose this error.
Often it  happens, when you mix string and number or string and date/time data types. 
If these data types are mixed, the function returns a string.
As Date/time and number data types cannot be mixed  the results is a #DATATYPE error.


Solution:

In Webi you must create a variable in which you have to convert and cast the data types in order to make them all homogeneous as datatype.
