Yes @Naveen B  what I have to do now? these all are getting null  thanks for responding

@ShahidaValiSyed04  Have you written any logic on the SAVE action and cleared any caches?

No I haven’t Written anything in save action But I created a button in that button when a user clicked on button it’s have to create a new record and have to generate all ID’s of new record

Here my Graph

@ShahidaValiSyed04  Can you please share your code here, instead of screenshot.

Ok

 public PXAction<SSPAgreement> Revision;

        [PXButton(CommitChanges = true), PXUIField(DisplayName = "Revision",

          MapEnableRights = PXCacheRights.Select,

          MapViewRights = PXCacheRights.Select)]

        public void revision()

        {

            // Acuminator disable once PX1050 HardcodedStringInLocalizationMethod [Justification]

            WebDialogResult result = Agreements.Ask(ActionsMessages.Warning, PXMessages.LocalizeFormatNoPrefix("Are you sure you want to create a new revision?"),

                MessageButtons.OKCancel, MessageIcon.Information, true);

            //SSPAgreement row = Agreements.Current;

            SSPAgreement dacObject = new SSPAgreement();

            if (result == WebDialogResult.OK)

            {

               // Agreements.View.RequestRefresh();

                //Agreements.View.Cache.Clear();

                //Agreements.View.Cache.ClearQueryCache();

                SSPAgreement agreementsOldRecord = Agreements.Current;

                SSPAgreement agreementsNewRecord = new SSPAgreement();

                agreementsNewRecord.TemplateCode = agreementsOldRecord.TemplateCode;

                agreementsNewRecord.Revision =(int)(agreementsOldRecord.Revision+1);

                agreementsNewRecord.AgreeNbr = (string)(agreementsOldRecord.AgreeNbr);

                agreementsNewRecord.Active = agreementsOldRecord.Active;

                //agreementsNewRecord.Descr = agreementsOldRecord.Descr;

                //agreementsNewRecord.LastModifiedByID = agreementsOldRecord.LastModifiedByID;

               // Agreements.Insert(agreementsNewRecord);

                Agreements.Update(agreementsNewRecord);

                Agreements.Cache.PersistInserted(agreementsNewRecord);

                throw new PXRedirectRequiredException(PXGraph.CreateInstance<SSPAgreementMaint>(agreementsNewRecord.TemplateCode), "Agreements") { Mode = PXBaseRedirectException.WindowMode.Same };

            }

           

        }

        protected void SSPAgreement_RowSelected(PXCache cache, PXRowSelectedEventArgs e)

        {

            var row = (SSPAgreement)e.Row;

            if (row.Active.GetValueOrDefault())

                this.Revision.SetEnabled(true);

            else

                this.Revision.SetEnabled(false);

            //PXUIFieldAttribute.GetCustomAttribute<SSPAgreement.>

        }

@ShahidaValiSyed04  Can you check with the below code

public PXAction<SSPAgreement> Revision;
        [PXButton(CommitChanges = true), PXUIField(DisplayName = "Revision", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
        public void revision()
        {
            WebDialogResult result = Agreements.Ask(ActionsMessages.Warning, PXMessages.LocalizeFormatNoPrefix("Are you sure you want to create a new revision?"),MessageButtons.OKCancel, MessageIcon.Information, true);

            if (result == WebDialogResult.OK)
            {               
                if (Agreements.Current != null)
                {                    
                    SSPAgreement agreementsOldRecord = Agreements.Current;
                    SSPAgreement agreementsNewRecord = new SSPAgreement();
                    agreementsNewRecord.TemplateCode = agreementsOldRecord.TemplateCode;
                    agreementsNewRecord.Revision = (int)(agreementsOldRecord.Revision + 1);
                    agreementsNewRecord.AgreeNbr = (string)(agreementsOldRecord.AgreeNbr);
                    agreementsNewRecord.Active = agreementsOldRecord.Active;
                    Agreements.Cache.Insert(agreementsNewRecord);
                    this.Actions.PressSave();
                    throw new PXRedirectRequiredException(PXGraph.CreateInstance<SSPAgreementMaint>(agreementsNewRecord.TemplateCode), "Agreements") { Mode = PXBaseRedirectException.WindowMode.Same };
                }
            }
        }

Hi @Naveen B 

its saving record on the same record But not creating a new One

Hi @ShahidaValiSyed04  Can you please check that are you passing the all KEY fields to create a new record?

Hi @Naveen B I have AgreeNbr  as a key field & already passed in Graph
