I have a requirement of code re usability. Please help me in achieving it. PFA which contains input and output. My aim is t reuse the code in functional map.

Thanks

Here is an example map.  I do not understand how this helps with code re-usability, or why you would need 'scratch' output cards in a functional map.

Thank you.

Thanks Paul. I have few questions.

1. I tried to use the Total variable to calculate TotalDiiference but I couldn't drag and drop it in the rule. How did you use the Total variable of the output to calculate TotalDifference?

2. Total = Mathematics+Science+History+Language; TotalDifference = PreviousTotal - (Mathematics+Science+History+Language). Since I couldn't use Total variable to calculate TotalDifference , I used all the variables again to get Total and then subtracted with PreviousTotal . Is there way that  can we create a temporary output card in functional map, calculate Total and store the output. Use the stored value wherever you want in the actual output of the functional map? 

3. If we go with your approach as per your Example, what is the order of execution of this functional map? I mean, whether always Total will be calculated first?

4. What do you mean by scratch'  output card?

5. I meant Re usability to  calculate the Total variable once and use it's output  wherever we want.

6. Lets say I have created a functional map which calculates Total and store the response in Total variable. Now can I call the functional map like this: TotalDifference = (PreviousTotal - f_calculateTotal(In1,In2,In3,In4))? I tried this but the result was always null.

Thanks

I have made a short video that shows how the mapping is done using drag and drop:

A.  As I have shown, there is no need to create a temporary output card (whch cannot be done anyway).

3. If we go with your approach as per your Example, what is the order of execution of this functional map? I mean, whether always Total will be calculated first?

A.  The rules are always executed in order

4. What do you mean by scratch'  output card?

A. 'scratch' card = temporary output card

5. I meant Re usability to  calculate the Total variable once and use it's output  wherever we want.

A.  My example shows how the result can be used in a later rule (in the functional map)

6. Lets say I have created a functional map which calculates Total and store the response in Total variable. Now can I call the functional map like this: TotalDifference = (PreviousTotal - f_calculateTotal(In1,In2,In3,In4))? I tried this but the result was always null.

A.  Your functional map call should include the 'Total:sequence:Out' reference, (as per my map) where the calculatoin has already been done.  So far example:

=F_NextLevel(PreviousTotal:sequence:In1 , Total:sequence:Out)

Thank you.
