Hi Hari,

1.You will have to check if you have any full download jobs from that table. You may need to increase the record length of the downloaded file.
2.Check if there are any jobs / programs using this table with SELECT * query. This will get impacted.
3.If any of your jobs / programs using this table dont use SELECT * way, then you will not have any impact.

You will also have to check for INSERT with just values and no column name list.

thanks for all your inputs/responses. But I need a generic impact analysis document where I can see what are all the components will be effected if something changes. Not only adding a column to the table.

I hope this is clear and please let me know if you need mroe information.

Thanks,
Hari

There are many 3rd party tools available to do the impact analysis. Generates various kinds of impact analysis report.
