How to override public virtual bool Approve(SourceAssign source) Method

Question

I need to override a piece of Acumatica’s Approval process that prevents from Apprving a Rejected document. Not sure why Acumatica has put this control in place but it happens many times for us that a documents gets rejected to add some supporting documents and when documentation completed, then this document can be approved. The piece of the code that prevents from approving a rejected document is in EP\Descriptor\Attributes.cs as follows:

public virtual bool Approve(SourceAssign source)
{
EPApproval item = (EPApproval)this._Rejected.SelectSingle(GetSourceNoteID(source));

if (item != null)
throw new PXException(Messages.CannotApproveRejectedItem);

if (UpdateApproval(source, EPApprovalStatus.Approved))
{
RegisterActivity(source, PO.Messages.Approved);

return true;
}

return false;
}

thanks,@andriikravetskyi35, and hi@arun83@Chris Hackettwith the above syntax, the base method will be called first I guess by the framework not the overridden one. In fact, I am not sure if the overridden method will be called at all. I believe the correct syntax is as follows.@arun83please test to see which one will work best in your case.[PXOverride]public override bool Approve(SourceAssign source){    // Do Stuff Here    // Invoke Acumatica’s base method or simply do not call it if you don't need it.    bool baseValue = base.Approve(source);    // Do Stuff Here    return ?;}

Hi, If you need to override this method, you could use this syntax:

>PXOverride]

public virtual bool Approve(SourceAssign source, Func<SourceAssign, bool> baseMethod)

{

// do your staff, code logic

// invoke base Acumatica’s method

bool returnBoolValue = baseMethod(source);

if (returnBoolValue == true)

{

// do your staff

}
