Adding a new checklist step in existing checklist profile

[Hanji]

Hi All,

I am currently adding a new config of Checklist requirement under an existing checklist profile. The requirement is to add 'Review ABAP/UI Deployment Sheet' as an additional checklist under 'Solution Documentation Review'. So the thing is, when this checklist is selected, the step 'Review Solution Documentation' automatically shows under it, however, the 'Review ABAP/UI Deployment Sheet' needs to be added manually as the second requirement. Does anyone know where I can fix this for it to get automatically shown?

Also, after a few other changes in SPRO specifically in Cat. Item Usage etc., I encounter below errors when creating a new Normal Change to be used for testing purposes.

Error Customizing of item cat. or item cat. usage required for all steps

Error Item 8000000010: Current and previous step number cannot be identical

Error Item 8000000010: Cyclical step order not permitted

Warning Message Item 8000000010: Enter a partner ID for checklist step

I'm possible thinking I should revert some changes performed as I did not encounter these errors the first time I did some changes.

Thank you.
