Bdc Recording Problem in IB52 TRANSACTION

Hi Guys ,

In IB52 transaction code under the Equipment table control after giving the install base number and functional location , i have to upload the excel data which contains the install base number and  equipment number ,but while recording if there are 11 items visible in table control already and if we upload one more line item from excel it gets overlapped on the last 11th item visible . Also Page down button is disabled and down arrow button in table control not capturing while recording ,

So kindly tell whether there is an alternative solution or some BAPI as it is very urgent ,
(FOR EQUIPMENT INSTALL BASE)

Thanks in advance .
