Hi Janareddy,

I presume Object B is the child record? If so you can create 3 formula fields in Object B which will copy values from Object A after you select the lookup field and save the record of Object B.

For example, I am considering text dataType, your formula will look like


If this resolves your issue, please mark this as the answer

HI janareddy,

if there is no provision to change value of B object field then go for Formula field options.

Suppose there is requirement like while creating B object record, as soon as you choosed parent record then others three fields should be autopopulated in editable mode before clicking save button, At that time you can modify existing value.This can't be possible through formla field, you need to go for Trigger.

If this is what you where looking for then please mark it as a solution for others benefits.

Thank You
