@bganapa @deathly809 Please help review.

Where is your main module markdown file? It seems these cmdlets are new, and therefore that file should have been updated as well.

@zyxyoshine @deathly809 moving forward, Stack PRs will need to target the AzureRM branch, not preview, so you may need to close this PR and open a new one that is based on the AzureRM branch (since this one is based on the preview branch and is bringing in a bunch of commits from the preview branch into AzureRM). I will work to bring in the Stack changes from the preview branch into AzureRM. It appears to be the following PRs:

• Feature/repairswagger: Adding powershell cmdlet for repair alert #7742
• [AzureStack] Update Fabric Admin Powershell cmdlet #7762
• [Azure Stack] Re-Generate Module Help #7911

Close this PR and open a new one that is based on the AzureRM branch.
