Field not automatically included in poline - acumatica

Question

I want to create a purchase order, the fields are not calculated : line.SiteID ; line.LineType ; line.ExpenseAcctID ; line.POAccrualAcctID
while in manual entry everything works correctly
order.OrderType = "RO";
order.Status="H";
order.BranchID=une_commandevente.BranchID;
order = poOrder.CurrentDocument.Insert(order);
order.VendorID = cmdfrs.Usrfournisseur;
order.OrderDate = DateTime.Today;
order.OrderDesc = "XXX";
order.VendorRefNbr="XXX";
poOrder.CurrentDocument.Update(order);
foreach (SOLine une_lignevente in PXSelectReadonly<SOLine,Where<SOLine.orderNbr, Equal<Required<SOLine.orderNbr>>,And<SOLine.orderType,Equal<Required<SOLine.orderType>>>>>.Select(this.Base,une_commandevente.OrderNbr,une_commandevente.OrderType))
{
var une_ligneventeext = une_lignevente.GetExtension<SOLineExt>();
if (une_ligneventeext.Usrfournisseur==cmdfrs.Usrfournisseur)
{
var line = poOrder.Transactions.Insert();
line.OrderType = "RO";
line.InventoryID = une_lignevente.InventoryID;
line.SiteID=3;
line.LineType = "NS";
line.ExpenseAcctID=39367;
line.POAccrualAcctID=39367;
line.OrderQty= une_lignevente.Qty;
line.UOM=une_lignevente.UOM;
poOrder.CurrentDocument.Update(order);
poOrder.Transactions.Update(line);
}
}
poOrder.CurrentDocument.Update(order);
poOrder.Actions.PressSave();
Thanks

There are a few adjustments needed in your logic:
For the header's cache, use the main view (Document) instead of CurrentDocument
For the header DAC, assign the Key values, then insert the row in the cache and then assign the rest of the values
For the iteration, there is no need to update the header's cache
For the grid DAC, there is no need to explicitly indicate the key values as those are defaulted from the header based on [PXDBDefault] attribute
I'd also recommend to update the cache after there is a known field that triggers events. For instance, entering the Vendor, defaults the vendor location.
Try this modified (and simplified) version:
order.OrderType = "RO";
order = poOrder.Document.Insert(order);
order.OrderDate = DateTime.Today;
order.VendorID = cmdfrs.Usrfournisseur;
poOrder.Document.Update(order);
order.BranchID=une_commandevente.BranchID;
order.OrderDesc = "XXX";
order.VendorRefNbr="XXX";
poOrder.Document.Update(order);
foreach (SOLine une_lignevente in PXSelectReadonly<SOLine,Where<SOLine.orderNbr, Equal<Required<SOLine.orderNbr>>,And<SOLine.orderType,Equal<Required<SOLine.orderType>>>>>.Select(this.Base,une_commandevente.OrderNbr,une_commandevente.OrderType))
{
var une_ligneventeext = une_lignevente.GetExtension<SOLineExt>();
if (une_ligneventeext.Usrfournisseur==cmdfrs.Usrfournisseur)
{
POLine line = new POLine();
line = poOrder.Transactions.Insert(line);
line.InventoryID = une_lignevente.InventoryID;
poOrder.Transactions.Update(line);
line.SiteID=3;
poOrder.Transactions.Update(line);
line.ExpenseAcctID=39367;
line.POAccrualAcctID=39367;
poOrder.Transactions.Update(line);
line.OrderQty= une_lignevente.Qty;
line.UOM=une_lignevente.UOM;
poOrder.Transactions.Update(line);
}
}
poOrder.Actions.PressSave();
Also, I'd recommend testing this in a fresh environment w/o customizations. Create a test button that instantiates the graph and creates a PO with a couple of lines.
