PO Spend Analysis in one currency (USD or Ledger Currency)

Summary:

PO Spend Analysis in one currency (USD or Ledger Currency)

Content (required):

We are using Oracle provided Analysis: PO Spend by Top Category

We found that the Spend is calculated using Formula:

sum("- Purchase Order Line Detail"."Price" * "- Purchase Order Line"."Ordered Quantity" by "- Procurement Item"."Category Name")

This calculation is without considering the Currency and we have POs in multiple currencies in one business unit.

We would like to analyze the Spend using any one currency either USD or Ledger Currency (which is the correct way).

Kindly suggest how we can run OTBI analysis in One Currency.
