Stored procedure without signature is not working

Hi all,
Im using stored procedure without signature .this procedure updates some records in db.i need to pass one input to this procedure which is numeric type is that while passing the input from wM

which one shoud i select should i use NUMERIC or should i use DECIMAL.

I would go with NUMERIC unless the data needs DECIMAL to be selected.

We need to ensure SP inputs SQL data types and Input Types we select are in sync and appropriate.
