feeling data in ALV using BDC

Hi Experts,

We have one requirement to fill data into particular row of ALV using BDC.

Basically we have to call one transaction and pass data into other transaction which has ALV as output. Data should be passed to particular row of ALV.

Anyone knows how to pass data to particular row of ALV using BDC?

Thanks in Advance.

Thanks and Regards,

Jigar Thakkar.
