BufferCopy.Clone vs BufferCopy.Copy

Kinetic ERP
1

In the process of doing an upgrade from 2023.2.22 to 2025.2.14, and needing some detail around the difference of BufferCopy.Clone Vs BufferCopy.Copy in an Epicor Function.

After performing an upgrade conversion I have errors stating that ‘BufferCopy’ does not contain a definition for ‘Clone’ When I look at the intellisense I see

I don’t really understand why there is duplication there. That’s the first thing. The next thing I really wanted to ask for people who are much more skilled than myself, is there a difference and if so could you explain?

Thanks.

The intellisense is just not complete, those are different signatures for the same thing basically.

Oops when I was meaning differences I was meaning differences between BufferCopy.Clone and .Copy. Support person hate post right there… Two questions in one… Sorry.

I have this buried in my notes.

var dsReceipt = bo.GetByID(vendorNum, purPoint, packSlip);
 
// 
// Example how to Copy a few Tableset rows to New Tableset
//
var dsNew = new Erp.Tablesets.ReceiptTableset { 
    RcvHead = { 
        Epicor.Data.BufferCopy.Clone(dsReceipt.RcvHead[0]) 
    },
    RcvMisc = {
        Epicor.Data.BufferCopy.Clone(dsReceipt.RcvMisc.Where(x => x.MiscSeq == seqNum).FirstOrDefault()),
        Epicor.Data.BufferCopy.Clone(dsReceipt.RcvMisc.Where(x => x.MiscSeq == seqNum).FirstOrDefault())
        //new Erp.Tablesets.RcvMiscRow { EnableToBuildYourOwn }
    }
};
 
dsNew.RcvMisc[0].RowMod = "U";
 
 
// 
// Example how to Copy a LINQ Row to Tableset
//
 
// Erp.Tablesets.ReceiptTableset 
var dsNew3 = new Erp.Tablesets.ReceiptTableset {
    RcvHead = { 
        Epicor.Data.BufferCopy.Copy<Erp.Tables.RcvHead, Erp.Tablesets.RcvHeadRow>(Db.RcvHead.Where(s => s.Company == Session.CompanyID 
                    && s.PackSlip == packSlip 
                    && s.VendorNum == vendorNum 
                    && s.PurPoint == purPoint).FirstOrDefault())
    },
    // Erp.Tablesets.RcvMiscTable
    RcvMisc = {
        // Erp.Tablesets.RcvMiscRow
        Epicor.Data.BufferCopy.Copy<Erp.Tables.RcvMisc, Erp.Tablesets.RcvMiscRow>(Db.RcvMisc.Where(s => s.Company == Session.CompanyID 
                    && s.PackSlip == packSlip 
                    && s.VendorNum == vendorNum 
                    && s.PurPoint == purPoint
                    && s.MiscSeq == seqNum).FirstOrDefault()),
        // Erp.Tablesets.RcvMiscRow     
        Epicor.Data.BufferCopy.Copy<Erp.Tables.RcvMisc, Erp.Tablesets.RcvMiscRow>(Db.RcvMisc.Where(s => s.Company == Session.CompanyID 
                    && s.PackSlip == packSlip 
                    && s.VendorNum == vendorNum 
                    && s.PurPoint == purPoint
                    && s.MiscSeq == seqNum).FirstOrDefault())
    }
};
 
dsNew3.RcvMisc[0].RowMod = "U";
 
bo.OnChangeMiscDocActualAmt(vendorNum, purPoint, packSlip, seqNum, _value, ref dsNew);
bo.Update(ref dsNew);
 
 
// 
// Example how to Copy a LINQ Row to a LINQ Row (Erp.Tables.RcvMisc)
//
 
// Epicor Clone and Copy both will create a new GUID when the target is a LINQ Row
var LINQtoLINQExample = Epicor.Data.BufferCopy.Clone(Db.RcvMisc.Where(s => s.Company == Session.CompanyID 
    && s.PackSlip == packSlip 
    && s.VendorNum == vendorNum 
    && s.PurPoint == purPoint
    && s.MiscSeq == seqNum).FirstOrDefault());
 
// If you want to Preserve the GUID you must use Copy with 3rd param true
Erp.Tables.RcvMisc linqRowExample2 = new Erp.Tables.RcvMisc();
Epicor.Data.BufferCopy.Copy(xrow, linqRowExample2, true);

//
// Other Examples
//
// Example 1
UD03Row copyRow = new UD03Row();
BufferCopy.CopyExceptFor(ud03Row, copyRow, "SysRowID");

// Example 2
Ice.Tables.UD05 NewUD05 = null;
Db.UD05.Insert(NewUD05);
BufferCopy.CopyExceptFor(UD05, NewUD05, UD05.ColumnNames.SysRevID, UD05.ColumnNames.SysRowID);
NewUD05.Key3 = Convert.ToString(quoteRow.QuoteNum);
NewUD05.Key4 = Convert.ToString(quoteRow.QuoteLine);

Not sure why they removed Clone. I liked it.

We had to switch to something like

var newJcRow = new Erp.Tablesets.JobClosingRow();
Epicor.Data.BufferCopy.Copy(jcRow, newJcRow);
ds.JobClosing.Add(newJcRow);

Looks like Copy replaces Clone now.

This worked for me (2025.2.6):

CallService<UD100SvcContract>((svc) =>
  {
    var ds = svc.GetBySysRowID(Guid.Parse("2d766025-cdff-44de-b79e-1b53670b0458"));
    var dsRow = ds.UD100.First();
    
    var dsCopy = new UD100Tableset();
    var dsRowCopy = BufferCopy.Copy(dsRow);

    dsCopy.UD100.Add(dsRowCopy);
  });

There’s also this fun copy if you want to copy an entire tableset:

CallService<UD100SvcContract>((svc) =>
  {
    var ds = svc.GetBySysRowID(Guid.Parse("2d766025-cdff-44de-b79e-1b53670b0458"));
    var dsCopy = new UD100Tableset();

    DataCopy.CopyTableset(ds, dsCopy);
  });

Probably because it did something different than the .net DataSet.Clone() method. The standard method copies the DataSet object structure, but not the data itself.
