Hi,

You can create a function module by copying this function module and have the paramter type as you want and then you can check the type of the incoming variable using the utility method in the class

CL_ABAP_TYPEDESCR and the method is describe by data this will give you the type of the paramter then check if the type you want is the type you are getting in the FM and raise an exception if it is not.

Hello Kanti

The function module you are looking for is <b>NUMERIC_CHECK</b>.
