[FormDataFieldEventHandler(formDataFieldStr(SalesTable, SalesLine, SalesPrice), FormDataFieldEventType::Validating)]
public static void SalesPrice_OnValidating(FormDataObject sender, FormDataFieldEventArgs e)
{
var args = e as FormDataFieldCancelEventArgs;
FormRun formRun = sender.datasource().formRun();
boolean ret;
SalesTable  salesTable = formRun.dataSource(formdatasourcestr(SalesTable, SalesTable)).cursor();
SalesLine   salesLine = formRun.dataSource(formdatasourcestr(SalesTable, SalesLine)).cursor();
formRun = sender.datasource().formRun();
if (CustTable::find(salesTable.CustAccount).AcxOverrideSalesPrice == NoYes::Yes && salesLine.SalesQty > 0)
