Dear All,
Does anyone know the difference between SAP TDMS and Data Sync Manager.
My client asked me to realize a comparison, but it seems to be similary and it is very hard for me to find the difference between the both?
If someone has input about it...
Regards,
Benjamin
Hello Benjamin,
There are several additional features of TDMS over DSM -
- Flexibility to choose a RFC based transfer or File based transfer.
- Refresh multiple receiver clients with one File extract from a source system.
- Possibility to use File transfers in WAN independent environments
- Automate the whole copy procedure through PEM.
- Notification Services on the copy progress.
- Incremental solutions to extract a 100 % consistent Material Ledger data from a Live production
system with active ML.
- On device mobile applications for TDMS to keep you informed on the completed porgress
- Solution to copy Several industry Solutions with TDMS
- SAP TDMS can extract the required data from the snapshot system without causing any performance bottlenecks in the production system.
- many more new features to come.............................
And the very important aspect TDMS is completely backed up by SAP itself
Thanks,
Rajesh

Hello Rajesh,
There are some factual inaccuracies in your post that I would like to kindly point out:
Lastly, DSM is developed and supported by EPI-USE Labs, a company with more than 18 years' experience in SAP test data provisioning. The EPI-USE Labs global support team is renowned for exceeding customers' expectations. DSM is also an SAP certified product (including HANA certification).
Is it not in customers' best interest that they are provided with accurate information that allows them to make informed decisions? I would strongly suggest that customers research, and ideally evaluate, both products.
Kind regards,
Phillip
Hello Phillip,
Please let me point out the inaccuracies related to TDMS only posted by you. I have not spoken about any feature of DSM as I don't want to repeat the same mistake as done by you. Also I completely agree to your last point where you mention that “Is it not in customers' best interest that they are provided with accurate information that allows them to make informed decisions? I would strongly suggest that customers research, and ideally evaluate, both products”
Creates multiple receiver systems without impacting the sender system
Copies and transfers data across data centers
Can create export files for the same dataset
Master Data: You can choose this category to transfer only the master data of the selected BPL object.
Transaction Data: By choosing the transaction data category you can transfer only the
transactional data of the selected BPL object.
Processes category contains the BPL objects where business process-related data is transferred.
Custom Objects category contains the BPL objects that you create or copy. No objects are part of this category in the standard delivery from SAP.
Common Sub-objects category of BPL objects mainly includes the sub-objects in the other BPL objects.
The BPL Modeler feature is available which is integrated with the TDMS workcenter where you can model the BPL objects. You can view existing BPL objects, copy a BPL object and create a new BPL object using the BPL modeler based on your business requirement.
Another most important features of SAP TDMS is Data Scrambling and Shell Creation:
Data scrambling is a security measure to protect confidential data from internal and external threats. This security measure masks the sensitive data to prevent the risk of exposure to unauthorized users. The data
scrambling features with SAP TDMS help prevent the loss of sensitive data or the unauthorized access of confidential data in the non-production systems.
A system shell is an SAP system that only contains client-specific master data and the required client specific user and address data but no transactional data.
For more information on this product, please refer to the TDMS guides available in the Service Market Place.

just wanted to seek your opinion , guidance and direction... to see which is a better tool for generated reduced volume system copies from / for SAP Business Suite on HANA and BW on HANA.
TDMS and EPI-USE - do very well when SAP runs on Non-HANA RDBMS.... what about when SAP runs on In-Memory HANA....
Do you have any experience or can you advise - which is the best tool/ methodology for creating smaller Dev, QA etc from production size HANA systems..

Hi Ajay,
I cannot comment on the applicability and comparison between SAP TDMS and DSM, as I have never worked on DSM before. However, I would like to point out the fact that TDMS can be used very successfully on in-memory DB HANA (even in MCOD configuration). I performed a successful TDMS refresh for a customer on HANA (Version 97) last month. The current version of TDMS 4.0 (SP 10) is very robust for all SAP Solutions, and is a one-of-a kind tool when it comes to HCM Data Scrambling and BPL.
Feel free to reach out to me offline if you require any further information.
Best Regards,
Shouvik
Hi Ajay,
I'll answer on behalf of EPI-USE Labs for DSM. Many of our existing customers have migrated to the HANA database and we have also assisted new customers in migrating to the HANA platform by means of our products and services.
Some amazing performance results have been reported; this can be credited to the HANA technology itself but also speaks our efforts to optimize our solutions for HANA. We have worked closely with key customers that have large and specialized HANA installations to ensure that our solutions scale well to a variety of HANA implementations.
Another key metric is that customers have realized significant size reductions when subsetting production systems to refresh their QA and Development systems. The DSM product suite is certified for SAP HANA.
You can message me directly if you need more specific information or you can contact EPI-USE Labs support.
Best regards,
Marius

I would have to agree with your assessment of DSM; it does appear to have the same level of features as TDMS, the email feature is amusing too as TDMS 4.0 SP06 is the pre-req with TDMS.
Consideration for your client, going with DSM and needing SAP assistance for a data issue would not be likely to happen; so hopefully DSM can figure out any issues that arise.
And with TDMS you have the company that makes the product as making the application/DB setups; the understanding of how things work/flow or pulling a resource from another functional area to assist with a copy issue would be possible.

My company has been using TDMS for less than 6 months now and currently we are trying to have our functional team validate that time slices work so we can refresh all systems on a re-occurring basis.
I know prior to TDMS 4.0 SP05 it was required for someone to click down a list of executions, SP05 introduced a term known as PEM and it will automate the process (still requires an observer in case of an error). I have validated that with PEM you can set a weekend date/time for the data transfer piece and actually start the TDMS package ahead of time so all the 'heavy lifting' (aka data deletion/transferring) happens on a weekend during low hours. May be worth asking DSM folks if they can meet the same functionality.
Hi Billy,
This would be rather a quite late response in return to your response.
I was curious to understand how you had setup TDMS as you explained above.
My organization has been using TDMS for a while, but now we are looking for a better solution which can allow us to perform system refreshes frequently rather than quarterly or half yearly, but with the huge Production Databases upto 10+ TBs it makes a challenge to perform TDMS runs unless at the cost of highly powerful machine which can host TDMS, but still there are other challenges as well. We are looking for more robust and automated solution to do those kind of stuff.
We are starting to evaluate SAP LVM now for that particular situation.
Can you please elaborate about what you mentioned above or maybe point me to some resource/documentation about how you have been able to automate the TDMS runs just in time and manage to finish those and can run frequently. I would like to re-assess the solution.
Would appreciate your response.
Thanks & Have a nice day,
Akshay
Hello Akshay,
Could you please share some more details like the time slice used and the overall runtime that
you normally get while performing the client refresh using TDMS.
Also some top 5, time consuming activity that you face in your copy.
Although you are correct that more powerful machines can really help really optimize the runtimes,
but it may be possible that you may have not set up the TDMS copy properly to leverage the latest
optimizations and automation.
If you can provide some more details may be I can help you with some good suggestions.
Thanks,
Rajesh
Have you reviewed the BPL process of TDMS to see if that will work for your scenarios?
They have a lot of various things by default and I believe you can modify some to fit your requirements.
The PEM portion that I was referring to is an automated (until it errors) method of running through TDMS packages to avoid having to click down the list of actions and making the overall process take longer than needed.
