Hi,
If you want to calculate the value of 0040 final weight based on the values entered 0010,0020 and 0030
then create 0010 (W1), 0020(W2) and 0030(W3) as MIC's and in the control indicators of MIC 0040 (wf) activate calculated characteristic indicator.
In the inspection plan assign the MIC's in the sequential manner and when you assign the MIC 0040 maintain the relevant formula.
Once you make the above setting, when the user make RR for 0010, 0020,0030 MIC's value of 0040 will be calculated automatically by the system based on the values entered for 0010, 0020,0030
Hope this helps
Thanks
Kumar
