Newbie from Solidworks to Inventor. Unable to flatten sheetmetal, need guidance step to step.

You will probably need to follow the same steps as when you posted a similar part from here as it seems to be the same scenario:

Somehow I have deleted the necessary faces to thicken the material, but still giving error messages.

You didn't remove all the surfaces as shown in the example above. Take another look.

Thank you, missing deleting the last step (deleting inside faces).
