ELC calculation LOGIC is based on the values of ELC_COMP.CALC_BASIS and ELC_COMP.COST_BASIS.

ELC_COMP.CALC_BASIS decides whether the expense component is calculated on per-unit basis or value basis. ELC_COMP.COST_BASIS decides whether expense is calculated on SUPPLIER cost or Order cost. 

If COST_BASIS is 'S', ITEM_SUPPLIER_COUNTRY.UNIT_COST is USED to calculate expense. If COST_BASIS is 'O', ORDLOC.UNIT_COST is used. 

Table ELC_COMP STORES details of expense components along with rates, currency, cost_basis, calc_basis, etc. Table ORDLOC_EXP stores expense value at order, item, LOCATION and expense component level.
