Variables in FOX formulas in IP

Question

Hi All!
I would like to create FOX planning function that will be based on variables.
So, we have 2 variables AA and BB based on characteristics:
1. For 0CALMONTH with tech. name AA
2. For ZPROJECT with tech, name BB
I have a query, where at the first screen I make a selection for ready-for-input variables AA and BB. Then, at the second screen I execute planning function via button.
The sense of PF is copy all values of key figure ZKEYFIGURE from ZPROJECT = '0', 0CALMONTH = selected value of variable AA to ZKEYFIGURE of ZPROJECT = selected value of variable BB, 0CALMONTH = selected value of variable AA.
In master data of characteristic ZPROJECT we have different projects. but 1 is with technical name 0. This is the first master data in table.
DATA VAR1 TYPE 0CALMONTH.
DATA VAR2 TYPE ZPROJECT.
DATA VAR3 TYPE ZPROJECT.
VAR1= VARV(AA).
VAR2 = VARV(BB).
VAR3 = VARI(BB, 1).
{ZKEYFIGURE, VAR1,VAR2}={ZKEYFIGURE,VAR1,VAR3}.
After execution I see , that records were read, but 0 generated, 0 changed.
Maybe someone can advice what I do wrong?

Answer 1

Firstly,for 0calmonth,the from and to value is same as you are using the selected values of variable AA.
So no change in the value of 0CALMONTH
Secondly, in the fox formula,  for zproject, you are using the same variables. Hence the fox formula understands that there is no change in the value.
Define two variables for zproject, lets say proj1 and proj2.
Assign proj1 ='0'.
I have modified your fox code, give a shot with the following code, hopefully you might get the results as you want.
DATA VAR1 TYPE 0CALMONTH.
DATA PROJ1 TYPE ZPROJECT.
DATA PROJ2 TYPE ZPROJECT.
VAR1= VARV(AA).
PROJ1 = 0.
FOR EACH 0CALMONTH IN VARIABLE VAR1.
PROJ2 = VARI(BB,1).
{ZKEYFIGURE, PROJ2}={ZKEYFIGURE,PROJ1}.
Endfor.
