Examples include using SAP tools like R3loa...
- Q4. If you are using DMO to migrate a SAP system with sql DB on windows to HANA DB on linux, how the SUM will run? As there is a different SUM for windows and linux, will it use 2 different SUM in this case?
- Ans.
SUM will use a single SUM tool for the migration from SQL DB on Windows to HANA DB on Linux.
SUM tool is platform-independent and can be used for migrations between different operating systems.
The SUM tool will handle the conversion process seamlessly without the need for separate tools for Windows and Linux.
The migration process will involve steps to convert the database from SQL to HANA while also transitioning the op
- Q5. Can EHP 5 run on oracle 19C ?
- Ans.
No, EHP 5 cannot run on Oracle 19C.
EHP 5 is not certified to run on Oracle 19C.

SPDD changes are typically related to data dictionary objects, SPAU changes are re...
- Q7. Can we skip SPDD in preprocessing? If yes, what will happen? If no, what stops us from skipping it?
- Ans.
Skipping SPDD in preprocessing is not recommended as it can lead to inconsistencies in the system.
No, SPDD should not be skipped in preprocessing as it is a crucial step in handling modifications to the ABAP Dictionary objects during an upgrade or migration.
Skipping SPDD can result in inconsistencies between the data dictionary and the ABAP programs, leading to runtime errors and system issues.
SPDD is responsible for a...
- Q8. Why is SPDD need to be performed before execution phase and SPAU after execution?
- Ans.
SPDD is performed before execution phase to adjust dictionary objects, while SPAU is performed after execution to adjust repository objects.

SPAU is performed after execution to adjust repository objects like programs, function modules, screens, etc.
SPDD helps in adjusting the data dictionary objects to the new release...
- Q9. Can we perform SPAU before execution?
- Ans.
Yes, SPAU can be performed before execution.
SPAU can be performed to adjust modifications before executing a system upgrade or migration.
It allows for resolving any inconsistencies in custom objects before the actual upgrade.
Performing SPAU beforehand can help streamline the upgrade process and reduce downtime.
It is recommended to review and adjust modifications using SPAU prior to the upgrade to ensure a smooth transi
- Q10. Which process of SWPM will be used for export/import?
- Ans.

- Q12. Can we restore backup of HANA 1.0 on HANA 2.0 ?
- Ans.
No, backup of HANA 1.0 cannot be restored on HANA 2.0 due to compatibility issues.
Backup of HANA 1.0 is not compatible with HANA 2.0 due to differences in architecture and features.
Data structures and formats may have changed between the two versions, leading to potential data corruption if restored.
It is recommended to perform a system copy or migration instead of trying to restore a backup from HANA 1.0 to HANA 2.0.
- Q13. Why do we need shadow instance?

SAP HANA and Sybase do not follow the same approach as Oracle in creating additional tablespaces during upgrade.
In SAP HANA, data is stored in memory and does not require separate tablespaces like Oracle.
Sybase also does not create additional tablespaces during upgrade, as it follows a different database structure.
Both SAP HANA and Syba...
- Q16. Is it possible to upgrade without creating Shadow instance?
- Ans.
Yes, it is possible to upgrade without creating a Shadow instance.
Upgrade can be performed directly on the existing instance without the need for a Shadow instance.
This approach may save time and resources by avoiding the creation of a separate instance for the upgrade process.

- Q1. Internal working of hashmap
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.

If multiple keys hash to the same index, a linked list is used to handle collisions.
To retrieve a value, the key is hash...
