did deleting table will be captured in update set??

[KM SN]

1.  If not do we need to delete them in individual instances?
2. What need to be considered before deleting the table?
3. Is parent table fields going to be affected if I deleted child table?
4. Except schema map is there any other feature available in  ServiceNow to track where and where they are using this table?

Should be straight forward then. Moreover looks like this is for learning purpose.

learning from a issue/conflict with the help of you people.

1. Do we need to delete them in individual instances? No, deleting a table removes all its records in one action.

2. Considerations before deleting a table: Check for dependencies and back up data.

3. Impact on parent table fields when deleting a child table: No direct impact, but related records will be deleted.

4. Other features to track table usage: Application Repository and Metrics Application.

Mate did you just copy my answer and changed some formatting?

[Mark Manders]

Unfortunately, this is going on a lot. People looking to get the numbers of contributions up for some reason by just taking an answer, apply some formatting and pretend to be original. These people should get banned permanently, so they loose the number of contributions all together.
