How to Drag and Drop between two tables?

Hi all,

I've used the drag source and drop target for the tables. I want the drag and drop to work as follows

When we drag the MATNR in the first table to the MATNR of the second table, the field shouldn't be dropped into the second table but a link should establish between those two fields and field status of first table 'MATNR' should change in to 'Mapped'.

Please try to give some leads.

TIA.
