Require one record in grid added before saving parent

Hi @mmarklow44,

Yes you are right, you should be able to do it from the graph extension. You can override the Persist method in which you can check if there is at least one entry in the SalesPersons view then raise exception to if there are no entries in the view. Below is an example implementation you can start with,

    public class CustomerMaint_Extension : PXGraphExtension<PX.Objects.AR.CustomerMaint>
    {
        //const string salesPersonException = "Please Add atlease One Sales Person";
        #region Event Handlers
        public delegate void PersistDelegate();
        [PXOverride]
        public void Persist(PersistDelegate baseMethod)
        {
            if (Base.SalesPersons.Select().Count == 0)
            {
                throw new PXSetPropertyException("Please Add atlease One Sales Person", PXErrorLevel.RowError);
            }
            baseMethod();
        }
        #endregion
    }

Good Luck,
