cs01 bdc Page down problem table control

Hi experts ,

in my bdc program for cs01 I am not able to do the page up for new entries .

When counter is 14 , I am rsetting it to '01' and firing ok code P+ also .but it's overwriting on already existing lines instead of new lines .

Even in recording also , new entries ok code is not coming up .

Can you suggest me how to handle table control in cs01.
