Помогите найти причину не срабатывания TableUpdate?

Создаю LV "vocabview" таблицы "Vocab" с настройками

таблица vocab не буфферизирована

SELECT vocabview
CURSORSETPROP("Buffering", 3, "vocabview")
INDEX ON vocabview.num TAG num OF vocabtmp ASCENDING
CURSORSETPROP("Buffering", 5, "vocabview")

DBSetProp("vocabview","View","SendUpdates",.T.)
DBSetProp("vocabview","View","BatchUpdateCount",1)
DBSetProp("vocabview","View","MaxRecords",-1)
DBSetProp("vocabview","View","Prepared",.F.)
DBSetProp("vocabview","View","UpdateType",1)
DBSetProp("vocabview","View","Tables","register!vocab")
DBSetProp("vocabview","View","WhereType",2)

DBSetProp("vocabview.value","Field","UpdateName","register!vocab.value")
DBSetProp("vocabview.value","Field","KeyField",.F.)
DBSetProp("vocabview.value","Field","Updatable",.T.)


DBSetProp("vocabview.num","Field","UpdateName","register!vocab.num")
DBSetProp("vocabview.num","Field","KeyField",.T.)
DBSetProp("vocabview.num","Field","Updatable",.T.)

GOTO TOP IN vocabview

При попытке изменения

Replace vocabview.value WITH "asd"

IF TableUpdate(.T.,.T.,"vocabview") = .F.
LOCAL laerror(1)
=AERROR(laError)
MESSAGEBOX(laerror) &&Выдает 10
ENDIF

Messagebox(GETFLDSTATE(-1,"vocabview"))

Update не происходит GetFldstate показывает 121
Удаление же происходит нормально
