How to add attribute as custom field in detail line section of PO screen

HI @Naveen Boga yes, every time I try to select it and hit save, it reverts back to “TexEdit”:

@ashleyb  As suggested by Giri, Your DAC should be decorated with the PXSelector Attribute like below otherwise it will change it to TextEdit.

Here is the example for your reference.

    #region InventoryID   
        [PXInt()]
        [PXUIField(DisplayName = "Inventory ID")]
        [PXSelector(typeof(Search<InventoryItem.inventoryID>), new Type[] { typeof(InventoryItem.inventoryCD), typeof(InventoryItem.descr) }, 
            SubstituteKey = typeof(InventoryItem.inventoryCD))]
        public virtual int? InventoryID { get; set; }
        public abstract class inventoryID : IBqlField { }
        #endregion
