Z-Custom Fields to add in Line Item Tab -VIM_WP

Hi Experts,

We are trying to add Z-Custom fields in the Line item tab inside VIM Workplace screen. As of now, we have tried adding our Z-Field in structure /OPT/VIM_1RITEM and also do the configuration of the same in DP doc type and characteristic specific doc type configuration for our fields, still we are unable to display those fields.

Is there any steps / procedure to add these fields in Line item tab.
