System: SAP C4C 1905
I created two z_fields inside opportunity:
1. Opp header: total contribution margin
2. Opp -> Products -> new column: contribution margin (this field is an "Array"  it contains multiple values)
I created a workflow with Rule Type: Field Update.
This workflow should update the 1. field "total contribution margin" with the sum of all values inside the 2. field "contribution margin".
I tried this formula: "total contribution margin" = "total contribution"
Formula result and field to be updated are not of same type. Or given formula is not valid.
How do I address all the single values inside "contribution margin", sum them up and store them into "total contribution margin"?
Thanks for your help!
