Formula
Hi All,
I have a requirement and this is a very rare formula. Please help me with the same.
In Numbered list has Duplicate Products for different parents.
For Ex: Product A is a parent member it has a 3 Childs(D, E, F)
Product B is a parent member it has the same 3 Childs(D, E, F)
Product C is a parent member it has the same 3 childs (D, E, F).
We need to move all E product data to D.
Calucualtion D = D + E
PARENT  CHILD  Data before logic  Data After logic  
A  
D  100  300  
E  200  0  
F  300  300  
B  
D  100  300  
E  200  0  
F  300  300  
C  
D  100  300  
E  200  0  
F  300  300 
Can you please help me with how to write this calculation. Hope we understood.
Regards,

HI @NAIDU,
I have a solution for you!!
Please see below.
Here I have used system generated Id as that will be sequential and would work in this case.
System Id : To get the back end "#" number
System Id +1 : To get the next item
Find item : Converting the above number to list format
Units_Staging : To bring in the value for D and E with respect to the above stated condition
Final Units : Final Output
Hope his helps!!

Hello @NAIDU
There are several ways you could do it. Using formulas, using process etc.
But keep PLANS and DISCO in mind. The solution must be sustainable.
I strongly advice not to use Hard coded formulas, today the transition is from E==>D, tomorrow it could be different and there could be multiple transitions. Consider all scenarios.
Never use the # code of the numbered list.
I modeled the following for a single transition, you could extend it for multiple transitions.
I created three lists, a flat list for parent, a flat list for child and the numbered list.
Created a transition model to accept input on what to transition from and to.
Created a module to do the transition calculations as follows,
Line item formulas,
Data Take Out IF Numbered List.Child = Transition.Move From THEN Data ELSE 0 Add In IF Numbered List.Child = Transition.Move To THEN 1 * Take Out[LOOKUP: Numbered List.Parent Item] ELSE 0 After Movement Data + Take Out + Add In It works as below, hope it helps.
Thanks

Both great solutions @ArunManickam and @kavinkumar
But a very valid point made by Arun in that this needs to follow DISCO and PLANS and be sustainable.
