Hi Hussain,
I understand it in two different ways as follows:
1. Need to charge different till 3000 KM i.e. Rs. 21.67 and Rs. 8 after that -
Suggestion: Use different scale for each KM amount while maintaining condition record
2. Need to have fixed amount of Rs. 65000 for any KM till 3000 KM and later on each KM with Rs. 8 -
Suggestion: In this case you may need to maintain two different pricing condition, condition update function and group exclusion together. This might get more complex.
Hope this helps. Do let us know if your case is not understood properly.
Best regards,
Abhinay
