Existing Index Changes D365FO

 

Change existing Index D365FO

 

As we all have a requirement in the past to perform the changes in the existing indexes, and as we know the customization is not allowed in the OOTB elements, so we couldn’t achieve this.

 

How we can achieve it?

 

In D365FO, we couldn’t delete or disable the existing index, but there is one way to achieve this.

We can disable the index on SQL level by using the SQL script even on prod.

 

Yes, you are reading correct, we can disable the index and it will not enable again during package deployment, please only disable the index not remove the index, otherwise, Microsoft classes will re-create the index during deployment.

 Now you can create the new index as per your requirements and it will work properly and will not make any conflict with the existing index, because it is already in the disabled state.

How you can disable the index?

 

  public void disableIndex(str _tableName, str _indexName)

    {

        str sql;

        Connection conn;

        SqlStatementExecutePermission permission;

        ;

       

            sql= strFmt("ALTER INDEX %1 ON %2 DISABLE;", _ indexName, _tableName);

            // sql = ‘delete from custTable’;

            permission = new SqlStatementExecutePermission(sql);

            conn = new Connection();

            permission = new SqlStatementExecutePermission(sql);

            permission.assert();

            conn.createStatement().executeUpdate(sql);

            // the permissions needs to be reverted back to original condition.

            CodeAccessPermission::revertAssert();

       

    }

Important

Before applying the index, please perform the analysis on your existing data, might possible

you can face the issue.
