How does “Logical assets, groups and pools” work on the Asset Register page?

Xero records what the invoice said, so one excavator bought on three invoice lines is three assets. Grouping says those lines are one physical asset: the register shows one row, its members underneath, with their cost and depreciation summed, and the Excel carries the group's Saral code on every member line. A pool is the same mechanism with the opposite intent — many different low-value items (hand tools, a year of small furniture) tracked as one line because tracking each costs more than it is worth. Both are presentation: Xero's lines are untouched, the totals are unchanged, and ungrouping restores the lines. Lines from different companies cannot be grouped together.
