Hi,

How I can override the CorrectInvoice action from the Correction graph extension?

I’m using this code, but the page give me an error.

public class Test : Correction
    {
        public static bool IsActive()
        {
            return true;
        }

        public override void Initialize()
        {
            base.Initialize();
        }

        public override IEnumerable CorrectInvoice(PXAdapter adapter)
        {
            return base.CorrectInvoice(adapter);
        }



    }

Error

Hi @edsonvelez64 

Can you look at these examples? 

How To Override Action Create At ... and  Stackoverflow

Graphs in Acumatica are handled differently from a normal OOP programing perspective.

Hi,

I try with this code but is not working. 

[PXOverride]
        public IEnumerable CorrectInvoice(PXAdapter adapter, Func<PXAdapter,IEnumerable> baseMethod)
        {
            return baseMethod(adapter);
        }

Error

Hi @edsonvelez64 

Can you try the following code?

namespace PX.Objects.SO.GraphExtensions.SOInvoiceEntryExt
{
    public class Test : PXGraphExtension<Correction, SOInvoiceEntry>
    {
        public static bool IsActive()
        {
            return true;
        }

        [PXOverride]
        public IEnumerable CorrectInvoice(PXAdapter adapter)
        {
            return Base1.CorrectInvoice(adapter);
        }
    }
}

Correction is already a graph extension.

Hi, @edsonvelez64  Try like below and hope this helps!

Provided sample code for Base graph and extended graph for easy understanding.

namespace PX.Objects.SO
{
    public class Correction : PXGraph<Correction>
    {
        public PXAction<SOOrder> CorrectInvoice;
        [PXUIField(DisplayName = "Correct Invoice", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select, Enabled = true)]
        [PXButton()]
        public virtual IEnumerable correctInvoice(PXAdapter adapter)
        {
            //Logic Here
            return adapter.Get();
        }
    }
    public class CorrectionExt : PXGraphExtension<Correction>
    {
        public static bool IsActive() => true; 
        [PXOverride]
        public delegate IEnumerable CorrectInvoiceDelegate(PXAdapter adapter);
        [PXButton]
        [PXUIField]
        public IEnumerable CorrectInvoice(PXAdapter adapter, CorrectInvoiceDelegate BaseMethod)
        {
            //Logic Here
           return BaseMethod.Invoke(adapter); 
        }
    }   
}
