Cannot alter the table 'Table_Name' because it is being published for replication.

Today I was altering Primary key columns datatype in a table and got below error in Transaction replication.

Msg 4929, Level 16, State 1, Line 1
Cannot alter the table 'Table_Name' because it is being published for replication.

I had taken following steps to solve the problem

• Remove table from the replication.
• Change the datatype of Primary key column.
• Add again add table to the replication and reinitialize the publication.
