Hi Bhupinder,
as far as I know it is not possible to back to an older version.
Please also check this document: SAP Cloud Applications Studio Deployment & Landscape Basics
If you really have only version 1 and 2, you con go this way:
- Upload your Version 1 again as a new Solution in DEV Tenant
- Disable your old Solution -> ATTENTION: the Data of new fields will get lost and it is not possible to reactivate with the Data! If you have some scoping definition in your Solution (BAC Element) this will be lost, too!
- know you can work with your new Solution (create Patch etc.)
- Upload this new solution to your 2. Tenant
- Disable old Solution on 2. Tenant --> Again: Data will get lost!
However the best way I think would be if you do a revers implementation in a Version 3.
Hope this helps.
Best regards,
Astrid
