How to pass in a parameter to a PXSelectBase

Hi @Naveen Boga !

Unfortunately, the thing I am overriding is just the part that prepares the command.  It gets executed elsewhere.

		public virtual PXSelectBase GetShipmentsSelectCommand(SOShipmentFilter filter, GetShipmentsSelectCommandDelegate baseMethod)
		{
			PXSelectBase cmd;

			string customFilter = string.Empty;

			switch (filter.Action)
			{
				case CreateInvoice:
					{
						SOShipmentFilterExt ext = PXCache<SOShipmentFilter>.GetExtension<SOShipmentFilterExt>(filter);

						ICSProcessShipmentsFilters test = stuff.Current;

						if (ext.UsrBatchType != null) 
						{
							customFilter = ext.UsrBatchType.Trim();
						}

						switch (customFilter)
						{
							case ICSConstants.QtyLessThan5:
								{
									cmd = new
										SelectFrom<SOShipment>.
										InnerJoin<INSite>.On<SOShipment.FK.Site>.
										InnerJoin<Customer>.On<SOShipment.customerID.IsEqual<Customer.bAccountID>>.SingleTableOnly.
										LeftJoin<Carrier>.On<SOShipment.FK.Carrier>.
										Where<
											SOShipment.confirmed.IsEqual<True>.
											And<Match<Customer, AccessInfo.userName.FromCurrent>>.
											And<Match<INSite, AccessInfo.userName.FromCurrent>>.
											And<Exists<
												SelectFrom<SOOrderShipment>.
												Where<
													SOOrderShipment.shipmentNbr.IsEqual<SOShipment.shipmentNbr>.
													And<SOOrderShipment.shipmentType.IsEqual<SOShipment.shipmentType>>.
													And<SOOrderShipment.invoiceNbr.IsNull>.
													And<SOOrderShipment.createARDoc.IsEqual<True>>.
													And<SOOrderShipment.shipmentQty.IsLess<Five>>>>>>.
										View(Base);

									break;
								}
//more stuff here but removed for brevity

			return cmd;
		}

Maybe I have to override another one where that command gets executed.  The first override would be to prepare the command and the second override would be to provide the actual value. 

I’ll try to find where in the graph the cmd gets executed and see if it can be overridden.

@Naveen Boga after looking a little deeper, I don’t think I need to be overriding the code that creates the cmd.  I need to override the method that applies the filters to that cmd.

Thanks for the insight.  FYI, your first answer is correct as it does answer my original question.  This answer WILL help me in the future and it explains how that parameter gets populated in the select command.

THANK YOU NAVEEN.
