Calculating and Saving the custom field - acumatica

Question

I have a bound custom field grossprofit added into the SOLine grid which is calculated based on Item UnitCost, AverageCost and Qty.
I have the code written into SOLine_CuryUnitPrice_FieldSelecting event. However, it is not saving into the Database.
Also, I need a total of all lineitems for the custom field as a TotalGrossProfit on Order summary. It is calculating but for some reason it is not reflecting on screen.
Can anyone suggest?
Here is the code
public class SOOrderExtension : PXCacheExtension<SOOrder>
{
#region UsrTotalGrossProfit
public abstract class usrTotalGrossProfit : PX.Data.IBqlField
{
}
protected Decimal? _UsrTotalGrossProfit;
[PXCurrency(typeof(SOOrder.curyInfoID), typeof(SOOrder.orderWeight))]
[PXDefault(TypeCode.Decimal, "0.0")]
[PXUIField(DisplayName = "Total Gross Profit")]
public virtual Decimal? UsrTotalGrossProfit
{
get
{
return this._UsrTotalGrossProfit;
}
set
{
this._UsrTotalGrossProfit = value;
}
}
#endregion
}
public class SOLineExtension : PXCacheExtension<SOLine>
{
#region UsrGrossProfit
public abstract class usrGrossProfit : PX.Data.IBqlField
{
}
protected Decimal? _UsrGrossProfit;
[PXDBCurrency(typeof(SOOrder.curyInfoID), typeof(SOOrder.discTot))]
[PXDefault(TypeCode.Decimal, "0.0")]
[PXUIField(DisplayName = "Gross Profit")]
public virtual Decimal? UsrGrossProfit
{
get
{
return this._UsrGrossProfit;
}
set
{
this._UsrGrossProfit = value;
}
}
#endregion
}
public class SOOrderEntryExtension : PXGraphExtension<SOOrderEntry>
{
protected virtual void SOOrder_RowSelected(PXCache cache, PXRowSelectedEventArgs e)
{
SOOrder row = e.Row as SOOrder;
if (row == null) return;
SOOrderExtension orderExtension = PXCache<SOOrder>.GetExtension<SOOrderExtension>(row);
foreach (SOLine soLine in Base.Transactions.Select())
{
SOLineExtension lineItem = PXCache<SOLine>.GetExtension<SOLineExtension>(soLine);
orderExtension.UsrTotalGrossProfit = orderExtension.UsrTotalGrossProfit + lineItem.UsrGrossProfit;
}
}
protected void SOLine_CuryUnitPrice_FieldSelecting(PXCache sender, PXFieldSelectingEventArgs e)
{
var row = (SOLine)e.Row;
if (row != null && Base.Document.Current != null && Base.Document.Current.Status != "C")
{
SOLineExtension opportunity = PXCache<SOLine>.GetExtension<SOLineExtension>(row);
InventoryItem inv = PXSelect<InventoryItem,
Where<InventoryItem.inventoryID, Equal<Required<InventoryItem.inventoryID>>>>.Select(new PXGraph(), row.InventoryID);
if (inv.ItemType == "F") // Stock Item
{
opportunity.UsrGrossProfit = (row.UnitPrice - invc.AvgCost) * row.Qty;
}
Base.Save.Press();
Base.Persist();
}
}
}

These are the two events that I would use.. you may have to change them to your version of C# i am using 7...
protected void SOLine_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
{
if (!e.row is SOLine row) return;
if (!e.oldRow is SOLine oldRow) return;
//check for unwanted status, if true return
if (Base.Document.Current.Status == "C") return;
//check for the fields to have value, if no return
if (!row.UnitPrice.HasValue || !row.Qty.HasValue) return;
//get row extension
var rowExt = row..GetExtension<SOLineExtension>();
//select inventory record
var invItem = (InventoryItem)PXSelect<InventoryItem,
Where<InventoryItem.inventoryID, Equal<Required<InventoryItem.inventoryID>>>>.Select(Base, row.InventoryID);
if (invItem == null) return;
//add value to field, no persist or save
if (inv.ItemType == "F") // Stock Item
{
rowExt.UsrGrossProfit = (row.UnitPrice - invc.AvgCost) * row.Qty;
}
}
protected virtual void SOOrder_RowSelected(PXCache cache, PXRowSelectedEventArgs e)
{
//this may not work in older versions of C#
if (!(e.row is SOOrder row) return;
var rowExt = row.GetExtension<SOOrderExtension>();
foreach (SOLine soLine in Base.Transactions.Select())
{
var lineItem = soLine.GetExtension<SOLineExtension>();
rowExt.UsrTotalGrossProfit += lineItem.UsrGrossProfit;
}
//this is probably why not showing up...
Base.Document.Cache.Update(Base.Document.Current);
}
