Question:

When editing an Account, Address, or Child Account, why do key symbols not appear for DCR Editable fields?

Answer:

When editing an account, address, or child account, key symbols, which denote a field is DCR controlled, will only appear next to fields that are configured with a DCR Field Type of DCR_vod or DCR_Required_vod. The key symbols will not appear next to fields that are configured with a DCR Field Type of either DCR_Editable_Required_vod or DCR_Editable_vod. This is working as designed.
