I have a picklist and a multi-select picklist field. The picklist values are same in both the fields. Whenever I chose a value in the picklist field and save the record, the picklist value should be selected in the Multi-Select picklist field.
Example: Picklist field has A, B, C, D..... Z values. Multi-select Picklist will also have A, B, C, D... Z values. When I choose B in Picklist field and save my multi-select Picklist also should have B selected as a value. Now if I chose F for my picklist field, Multi-Select picklist should have both B and F values selected in the background.
Can someone help me with this logic?
