Hi Remi,
I tried what you mentioned above, however I am getting the below error;
Invalid parameters for an operation
Operation AMT/ &Z102
Calculation rule ZDCP*83R1 ZERO=&Z10A ZERO=&Z10B AMT/ &Z102 PRI
Also, I checked the below link, in which I was not able to any operation where we can divide amount with temp variable or standard wage type.
Regards,
