Identify Updated column at subscriber side

Hi,

We have written some custom logic in replication SPs at subscriber side. What we are looking at is to identify if there is some way to find which column of a table has been changed.

Say for example table1 has 3 columns (col1, col2, col3) . There is some update happened in one of the row oftable1 and transactional replication has replicated the data to subscriber. SPs which will be responsible for this is sp_MSupd_dbotable1.  Say at publisher sidecol1 value got changed, can we identify in the SP sp_MSupd_dbotable1which column has changed?

Thanks in advance,
