How to extend an out of the box data entity method?

(0) ShareShare
ReportReport
Posted on by nayshIB 95

I have an out of the box entity that I've extended to include modified and created by fields. If a record existed before turning on the fields it's filled with a '?' and the customer doesn't want question marks in the output file, either the name or blank. In custom entities I had no problem adding code to the postLoad() method to change the '?'s to blank strings, but it's when I tried extending the out of the box entities.

An example here (shown below) https://community.dynamics.com/365/financeandoperations/b/365finopsknowledge/posts/how-to-extend-or-overwrite-dataentity-methods-in-d365-finance-and-operations-x is not working for me, the extended code is never hit when running the entity. I also tried using dataEntityViewStr isntead of tableStr for the extensionOf, neither are working.

Is this possible?

[ExtensionOf(tableStr(SalesOrderHeaderV2Entity))]
final class SWClass_SalesOrderHeaderV2Entity_Extension
{
   

    public void postload()
    {
        next postload();
       
        SalesOrderHeaderV2Entity SalesOrderHeaderV2Entity = this;
       

        SalesTable                  salesTable = SalesTable::find(SalesOrderHeaderV2Entity.SalesOrderNumber);

       
        SalesOrderHeaderV2Entity.customdate += date2Str(salesTable.createddateandtime, 213,
                                                                DateMonth::Digits2,
                                                                DateSeparator::Slash,
                                                                DateDay::Digits2,
                                                                DateSeparator::Slash,
                DateYear::Digits4);
        }
               
    }

}

    Hi nayshIB,

    If the value is based on a conditions, you can think of it as a calculated column or virtual field.This will not affect the field value of the original data entity.

    Please have a look at the document:docs.microsoft.com/.../data-entity-computed-columns-virtual-fields

    It seems I misunderstood your problem. To achieve the same thing, simply write a data update job and modify values of ModifiedBy1 and CreatedBy1. Then you don't have to decrease performance by overriding postLoad().

    Using update_recordset is the best way to implement the data update job.

    If you was in a situation where it's not possible, you would be a better of writing a computed column than populating a virtual field in postLoad(). But in this case, neither seems to be needed.

    Here's specifically what I'm using for the VendorInvoiceHeaderEntity and I have breakpoints in postLoad, it isn't being hit for some reason.

    [ExtensionOf(tableStr(VendorInvoiceHeaderEntity))]
final class VendorInvoiceHeaderEntity_Extension
{
     public void postLoad()
    {
        next postLoad();

        if (this.ModifiedBy1 == "?") this.ModifiedBy1 = "";
        if (this.CreatedBy1 == "?") this.CreatedBy1 = "";
    }
}

    Using CoC on postLoad() should work without problems.

    But the rest of the code is wrong and it won't even compile (if CustomDate is a date, as the name suggests). It's trying to add two dates together, which makes no sense. And it even converts one of them to a string, therefore it wants to add a string to a date, which makes even less sense. And the field is CreatedDateTime, not CreatedDateAndTime.

    The author meant something like this:

    [ExtensionOf(tableStr(SalesOrderHeaderV2Entity))]
final class My_SalesOrderHeaderV2Entity_Extension
{
    public void postLoad()
    {
        next postLoad();
		
		SalesTable salesTable = SalesTable::find(this.SalesOrderNumber);
		this.CustomDate = DateTimeUtil::date(salesTable.CreatedDateTime);              
    }
}

    By the way, please use Insert > Insert Code (in the rich-formatting view to paste source code, as I did.

    Hi,

    You can use an event handler for "OnPostedLoad" event. I think That should serve your requirement.
