While preparing the Workbench, doing calculation with two or three attribute columns its working fine, but in future the source data if its comes with null values the FME workbench is getting failed.
To avoid failing the workbench currently we need to use filter transformers to success the process, so that the workbench is becoming big.
If we have any option to filter null values and redirect to null port in each calculation transformers like ExpressionEvaluator, DateTimeCalculator and if possible in Arithmetic editor.
