Fields with automatically showed details for input
We have again met the need to figure out how to configure fields in which automated details would show up after user inputs some value in the nearby field. Like there are already preset configuration in many transactions, e.g. VA41 where you input or choose a value from search help for a ship-to and sold-to parties and then after clicking in other place or pressing 'Enter' - in the fields beside those field the detailed information comes up - like name / address/ postal code/ city
We need to replicate this action for custom fields.
Your suggestions how to do that are very very welcomed?
