I've found that I'm doing this incorrectly and need some assistance.

What would be the proper way to adjust the length of a column's datatype
when I have transactional replication setup?

I've attempted to drop the column using sp_repldropcolumn and got the
message that the column has an index.  So I simply opened the MANAGE INDEXES
on the table and dropped the index, used the sp_repldropcolumn, used
sp_repladdcolumn with the new datatype size and when I was all finished I
checked my replication and found that it reported an error on the
distribution agent because it indicated that the index that I had dropped
was needed for the column that I altered.

There has to be a proper way to do this, can someone provide me the steps?

Thanks!
