Form Data Source Method override COC D365FO


Here is the sample how can you override the form data-source event.

In this demo we have created the extension of HcmWorker form data-source (HcmWorker).


Here is the original method  of HcmWorker data-source 

    public boolean validateWrite()
        {
            boolean ret;

            ret = super();

            if (ret)
            {
                partyForm.validateWrite();
            }

            return ret;
        }

Here is the  code to create form data-source extension class 

[ExtensionOf(formdatasourcestr(HcmWorker, HcmWorker))]
final class Demo_Extension
{

}


Here is the code to override the data-source method through COC.

[ExtensionOf(formdatasourcestr(HcmWorker, HcmWorker))]
final class Demo_Extension
{
    public boolean validateWrite()
    {
        boolean ret;

        ret  =  next validateWrite();

        if (ret)
        {
                    
           /// do your code here
        }

        return ret;
    }

}


In last perform Build & Sync.
