Hi,

  Am working on odoov11 , i created a custom field x_difference which can calculate the difference between two fields open_meter_reading and close_meter_reading, i tried the following code in the compute field while creating the field

​x_difference = close_meter_reading - open_meter_reading​

but its not working, can anyone say the proper codes to use them to compute the difference?

if possible give the detail structure of the field that which datatype to used,what we have to write in related field, dependencies, and compute...

Thank you

Hi,  

try this,

     self.x_difference = self.close_meter_reading - self.open_meter_reading​    

Thanks
