+Use Cases / Context

+environment and most of the purchases are made in a currency other than
+the main currency of the company.
+
+Configuration
+=============
+
+Go to **Settings** → **Purchase**:
+
+- Set the **"Default Purchase Currency"** to an available currency
+- Press the **"Save"** button to apply the changes
+
+Usage
+=====
+
+Once the module is configured, the default currency will be set:
+
+1. As the default value for the **"Currency"** field in **Request for Quotation**.
+2. As the default **Journal Currency** in **Vendor Bill**.
