Hi Justin,
I tested the "Label Column" (previously known as Description Mapping) function on HANA SP08. I have to add the description attribute (for example MAKTX) to the output before I can select it in the label column. I agree with you that there is not much difference by using a standalone column as the description and not bothering with the label column. And I can't find the way to rename a label column attribute as <attribute>.description as described in the F1 help. I don't know if something is changed by SAP again?
Thanks,
Jerry
