I have a custom module Eurotax
API Eurotax
This module contains 2 fields:
1: EUROTAX, API Name EUROTAX, Data Type Number
2: ROK, API Name ROK, Data Type Pick List
I need to add a new field (for example Field3) that will be the combination of the values of the two fields above.
Example 1:
Field1: EUROTAX, value 1234
Field2: ROK, value 2024
3: The new field:
Field3: value 1234-2024 (Field1 + dash + Field2)
-----------------
Example 2:
Field1: EUROTAX, value 5673456
Field2: ROK, value 2025
3: The new field:
Field3: value 5673456-2025 (Field1 + dash + Field2)
Could anyone help to write a custom function to received a new field (Field3)?
Should I use workflow rules or something else?
