Hi Team,

I have 2 customized fields(“COO, Date Code”) in LineDetails on Labor Screen, upon release i want to insert these field values to LineDetails in Receipt. I’m using the below code to do so, but it is not insert the fields in Receipt. could you please help me on this.

namespace PX.Objects.AM
{
    public class LaborEntry_Extension : PXGraphExtension<LaborEntry>
    {
        #region Event Handlers
        public delegate IEnumerable ReleaseDelegate(PXAdapter adapter);
        [PXOverride]
        public IEnumerable Release(PXAdapter adapter, ReleaseDelegate baseMethod)
        {
            var amtransplit = Base.splits.Select().FirstTableItems.ToList();
            amtransplit.ForEach(f =>
            {
                f.ExpireDate = DateTime.Now;
                Base.splits.Update(f);
                Base.Save.Press();
            });

            baseMethod(adapter);
            PXLongOperation.WaitCompletion(Base.UID);
            var amheader = Base.batch.Current;
            if (amheader != null)
            {
                
                var inreceiptGraph = PXGraph.CreateInstance<INReceiptEntry>();

                var batchHeader = PXSelect<INRegister, Where<INRegister.docType, Equal<INDocType.receipt>, And<INRegister.srcRefNbr, Equal<Required<INRegister.srcRefNbr>>>>>.Select(Base, amheader.BatNbr).FirstTableItems.FirstOrDefault();   
                if (batchHeader != null)
                {
                    inreceiptGraph.receipt.Current = batchHeader;
                    amtransplit.ForEach(f =>
                    {
                        var amsplitExt = f.GetExtension<AMMTranSplitExt>();
                        var splits = PXSelect<INTranSplit, Where<INTranSplit.docType, Equal<INDocType.receipt>, And<INTranSplit.refNbr, Equal<Required<INTran.refNbr>>, And<INTranSplit.lineNbr, Equal<Required<INTran.lineNbr>>>>>>.Select(Base, batchHeader.RefNbr, f.LineNbr).FirstTableItems.FirstOrDefault();

                        if (splits != null)
                        {
                            var intranExt = splits.GetExtension<INTranSplitExt>();
                            intranExt.UsrCOO = amsplitExt.UsrCOO;
                            intranExt.UsrDateCode = amsplitExt.UsrDateCode;
                            inreceiptGraph.splits.Update(splits);
                            inreceiptGraph.Save.Press();
                        }
                    });
                }
            }
            return adapter.Get();
        }
        #endregion
    }
