Appears to be: null value during a copy operation probably of a BPM parameter ‘fromItem’ during access of UD03 and possibly within a customization. Most of the debugging information is in the trace to get you started, but just a guess with this bit of information.

Error is only coming from the Function and the BPM

Same code is working in Customization and in Kinetic Layer

Clint already told you lol.

Let’s see the code.

Looks like your input object is null on a BufferCopy.

I see no reference to Buffer Copy. You sure this is the offending code?

Also, are you sure that CustShipBO.CheckPCBinOutLocation doesnt clear your RowMod?

CustShipBO.CheckPCBinOutLocation doesn’t clear the RowMod

Does anyone have a fix for this?

Did you validate you had data being returned from the GetByID?

Check if the data exists before trying to copy it.

var originalShipHeadRow = CustShipOriginalTS.ShipHead.FirstOrDefault();
if (originalShipHeadRow != null)
{
    var newRow = CustShipTS.ShipHead.NewRow();
    BufferCopy.Copy(originalShipHeadRow, newRow);
    CustShipTS.ShipHead.Add(newRow);
}
else
{
    // Throw error....... 
}

Yes, data is returning from the GetByID.

Error is coming when the UpdateMaster is called

@aarong Tried your code. Still getting the same error.

https://www.epiusers.help/t/value-cannot-be-null-fromitem-in-buffercopy-getrowcopier/95077

They are saying error is coming because of the credit card issue
Can someone explain this

You show different pieces of code and not possibly the corresponding error to said code. This makes it difficult to assist in your issue, but I would start by examining that you have actual data present to work with here:

    Erp.Tablesets.CustShipTableset CustShipTS = CustShipBO.GetByID(ReqiPackNum);
    
    var vtsShipHead = CustShipTS.ShipHead.FirstOrDefault(xRow => xRow.Company == Session.CompanyID && xRow.PackNum == ReqiPackNum);
    if(vtsShipHead != null)
    {
      strMsg += " CustNum: " + vtsShipHead.CustNum + ", ReadyToInvoice: " + vtsShipHead.ReadyToInvoice + Environment.NewLine;
      
      iCustNum = vtsShipHead.CustNum;
      
      vtsShipHead.ReadyToInvoice = true;
      vtsShipHead.RowMod  = "U" ;
    }
    // vvv this line looked to be the other error you posted and could have had null data again in your CustShipTS
    CustShipBO.CheckPCBinOutLocation(ref CustShipTS, out lineNum, out belongToAnotherPC, out strpcOutsideMessage);

or

      CustShipBO.UpdateMaster(ref CustShipTS, false, true, false, true, true, false, true, ReqiPackNum, iCustNum, out stropReleaseMessage, out stropCompleteMessage, out stropShippingMessage, out stropLotMessage, out stropInventoryMessage, out stropLockQtyMessage, out stropAllocationMessage, out stropPartListNeedsAttr, out stropLotListNeedsAttr, out strshipCreditMsg, out blncError, out blncompError, out strmsg, out stropPostUpdMessage, out blnupdateComplete, out blncheckComplianceError, out blnchangeStatusError, out blncheckShipDtlAgain);

I stand by my question did you validate you have appropriate DATA in those Tablesets?

16

As @aarong suggested, I tried using the BufferCopy to fix the error.
Both of my codes are identical except for the fact that one includes Buffer Copy and the other does not.

Tablesets contain the appropriate data. The UpdateMaster is where the error is consistently appearing.
