Hi @param2022  Yes

Ext.Price = Qty * Unit Price

Amount = Qty * Unit Prie - Discount Amount 

1. Do you have any customization with those fields? if yes, please unpublish and check to identify the root cause
2. I see there are no line level discounts but any Document level discount applied

@Naveen Boga I have customization that updates the Ext.Price for the Non Stock Items. Here is the code snippet. The Ext.price is updated but not the Amount.

CROpportunityProducts row = (CROpportunityProducts)e.Row;

CROpportunityProductsExt rowExtension = row.GetExtension<CROpportunityProductsExt>();

row.CuryExtPrice = rowExtension.UsrInternalExtCost + (data * rowExtension.UsrInternalExtCost);

Hi @param2022  Can you share the complete event code?

@Naveen Boga plz see it below

protected void CROpportunityProducts_RowUpdated(PXCache cache, PXRowUpdatedEventArgs e)
        {
            CROpportunityProducts row = (CROpportunityProducts)e.Row;
            CROpportunityProductsExt rowExtension = row.GetExtension<CROpportunityProductsExt>();
            if (row is null) return;
            InventoryItem inventoryItem = PXSelectorAttribute.Select<CROpportunityProducts.inventoryID>(cache, row) as InventoryItem;
            if (inventoryItem is null) return;
            InventoryItemCurySettings curySettings =
                 InventoryItemCurySettings.PK.Find(
                 this.Base, inventoryItem.InventoryID, rowExtension.UsrInventoryCuryId ?? "USD");

            bool isStkItem = inventoryItem.StkItem ?? false;
            if (!isStkItem)
            {
                // get inventoryItemCurySettings extension
                InventoryItemCurySettingsExt inventoryItemCurySettingsExt = curySettings.GetExtension<InventoryItemCurySettingsExt>();
                if (rowExtension.UsrSelectedPriceModifier != 0 || rowExtension.UsrSelectedPriceModifier != null)
                {
                    PriceModifier priceModifier = PXSelectorAttribute.Select<CROpportunityProductsExt.usrSelectedPriceModifier>(cache, row) as PriceModifier;
                    if (priceModifier != null)
                    {
                        decimal data = (decimal)priceModifier.Percentage / 100;
                        row.CuryExtPrice = rowExtension.UsrInternalExtCost + (data * rowExtension.UsrInternalExtCost);
                        row.ExtPrice = rowExtension.UsrInternalExtCost + (data * rowExtension.UsrInternalExtCost);
                    }
                }
            }
        }

Hi @param2022  Can you please try with the below code?

     protected void CROpportunityProducts_RowUpdated(PXCache cache, PXRowUpdatedEventArgs e)
            {
                CROpportunityProducts row = (CROpportunityProducts)e.Row;
                CROpportunityProductsExt rowExtension = row.GetExtension<CROpportunityProductsExt>();
                if (row is null) return;
                InventoryItem inventoryItem = PXSelectorAttribute.Select<CROpportunityProducts.inventoryID>(cache, row) as InventoryItem;
                if (inventoryItem is null) return;
                InventoryItemCurySettings curySettings =
                     InventoryItemCurySettings.PK.Find(
                     this.Base, inventoryItem.InventoryID, rowExtension.UsrInventoryCuryId ?? "USD");

                bool isStkItem = inventoryItem.StkItem ?? false;
                if (!isStkItem)
                {
                    // get inventoryItemCurySettings extension
                    InventoryItemCurySettingsExt inventoryItemCurySettingsExt = curySettings.GetExtension<InventoryItemCurySettingsExt>();
                    if (rowExtension.UsrSelectedPriceModifier != 0 || rowExtension.UsrSelectedPriceModifier != null)
                    {
                        PriceModifier priceModifier = PXSelectorAttribute.Select<CROpportunityProductsExt.usrSelectedPriceModifier>(cache, row) as PriceModifier;
                        if (priceModifier != null)
                        {
                            var extPrice = row.CuryExtPrice;
                            decimal data = (decimal)priceModifier.Percentage / 100;
                            row.CuryExtPrice = rowExtension.UsrInternalExtCost + (data * rowExtension.UsrInternalExtCost);
                            cache.RaiseFieldUpdated<CROpportunityProducts.curyExtPrice>(row, extPrice);
                        }
                    }
                }
            }

@Naveen Boga that worked thank you.

Glad that I helped you with the above code and thanks for sharing the update! @param2022 

Hi @param2022 and @Naveen Boga, do you have a code that updates the Ext.Price for the Stock Items? Tia.

@sharmaineongyaco56  Can you please let us know when you wanted to update Ext  Price field?

We want to update some incorrect Ext. Price on the Sales Order with already completed status.
