Set PurchReqLine.BuyingLegalEntity default value is blank

I am a newcomer to D365, I encountered a problem in the development, requesting a new purchase request line to purchase a legal person with a default value of empty, tried a variety of methods, his default value can not override the following is my code.

[ExtensionOf(formDataSourceStr(PurchReqTable, PurchReqLine))]
final class IWS_PurchReqTable_FDS_Extension
{
    
    public void initValue()
    {
        next initValue();
        ttsbegin;
        PurchReqLine purchReqLine = this.cursor();
        purchReqLine.BuyingLegalEntity = 0;
        purchReqLine.modifiedField(fieldNum(PurchReqLine,BuyingLegalEntity));        
        //this.rereadReferenceDataSources(); //Refresh value

        //this.research(1);
        

        FormReferenceGroupControl BuyingLegalEntity = this.formRun().design().controlName(formControlStr(PurchReqTable, PurchReqLine_BuyingLegalEntity));
        FormStringControl BuyingLegalEntity_DataArea = this.formRun().design().controlName(formControlStr(PurchReqTable, PurchReqLine_BuyingLegalEntity_DataArea));
        BuyingLegalEntity.value(0);


        BuyingLegalEntity.resolveChanges();
        BuyingLegalEntity.referenceDataSource().research(1);
        BuyingLegalEntity.modified();
        //BuyingLegalEntity_DataArea.text('');
        //BuyingLegalEntity_DataArea.modified();

        purchReqLine.BuyingLegalEntity = 0;
        purchReqLine.modifiedField(fieldNum(PurchReqLine,BuyingLegalEntity));
        //purchReqLine.update();
        //purchReqLine.insert();
        this.rereadReferenceDataSources();
        //this.refresh();
        //this.reread();
        this.resetLine();
        ttscommit;
    }
    //End

}
