Defaulting a segment value (Depreciation expense account) on Web ADI template from another column on

Hi,

We have the same values for Segment 2 of the Location Flexfield and Segment 2 of the Accounting Flexfield (COA). The client requirement is to validate that value entered for Location flexfield and the value selected for Location segment in the Depreciation expense is the same.

Can we use formula on the WEB ADI layout to achieve this? If yes, where do we see the segment detail on the layout. When I check the layout, we only have a column for Location and one column for Expense account in the layout. How do we select a specific segment in this?

Thanks & regards,
