Add Custom Column in Appointment for Inventory ID field.

Hi ​@bjani23 
Which option are you selecting while customizing the attribute — Append to original or Replace original?
I believe you need to select Append to original.

 

Hope, it helps!

You should be able to add the field using the customization project editor. Click the Edit Selector Columns under the Inventory ID field like shown below, then click Add Columns, and go to custom and select your custom field. That will only work if your custom field is from an extension of the InventoryItem class, but I assume it is. It will then create a PXCustomizeSelector Columns with all the original columns as well as your custom columns.

[PXMergeAttributes(Method = MergeMethod.Merge)]

[InventoryIDByLineType(typeof(FSAppointmentDet.lineType), new Type[] {
            typeof(InventoryItem.inventoryCD),
            typeof(InventoryItem.itemClassID),
            typeof(InventoryItemExt.usrMANUFAC),
            typeof(FSxServiceClass.mem_RouteService),
            typeof(InventoryItem.itemStatus),
            typeof(InventoryItem.descr),
            typeof(InventoryItem.itemType),
            typeof(InventoryItem.baseUnit),
            typeof(InventoryItem.salesUnit),
            typeof(InventoryItem.purchaseUnit),
            typeof(InventoryItem.basePrice),
            typeof(FSxService.actionType)
            }, Filterable = true)]

Above like works fine.
