Hi Nachappa,
SQRT: This function is used to return the square root of the argument n (which is supported)
CAGR to the power of 1/4 can be written as ((CAGR to the power of 1/2)to the power of 1/2) which is nothing but
sqrt(sqrt(CAGR)) = The value which you need
Hope this is correct!!

Hello All,
I have scenario where I have a HANA DB (only HANA Database), which I access through studio, it is not BW on HANA system.
And I have got ECC,CRM,APO systems with traditional DB's setup for replication to HANADB via SLT.
Like as shown below...
ECC -->(SLT)--> HANADB
CRM -->(SLT)--> HANADB
APO -->(SLT)--> HANADB
Now that I am getting the required data from all 3 SAP systems to HANADB.
My requirement is I need to some data out of HANADB (NOT BW ON HANA) to get replicated to SAP APO systems.
Just to be a little clear, its like a setup of Export Datasource from traditional BW HANA system to APO system.
But in our scenario we don't have BW on HANA its just HANADB we want data replication done from HANADB to APO system.
Like
HANADB --> APO.
Kindly Note: If SLT can perform the integration like APO --> SLT --> HANADB, please keep in mind we should consider
medium to high data loads.
Can any of you provide your inputs on this scenario if its possible and if so how to proceed.
Regards,
Kishore

This is very helpful Abani thanks!
Extending that scenario a bit; I currently have BODS jobs on my HANA sidecar that snapshot SLT replicated BSEG data from ECC Hana. Assuming I expose the BSEG table as a virtual table in my sidecar using SDA, do you imagine I can point the BODS job to the virtual table rather than the replicated table?
Thanks, much,
Eric
Hi Eric - I'm not sure, if BODS recognizes virtual tables. If it does (It should), then you should be be able able to use in BODS job.
However, be aware of the volume of data transfer across the network.
Regards
Abani
Understood, it can't be worse than SLT-ing the entire table, which is what we are trying to avoid. When we do system overlays it takes 4-5 days to re-replicate BSEG currently.
I'd rather just re-run a snapshot job.
Thanks much,
Eric
Wait, so the transformation is taking place on the ETL side and not on HANA?
If that's the case, then you'll need to make sure you obey to the underlying DB rules (Oracle, MS SQL Server, etc).
Anyhow, most of the relational databases out there (if not all) will offer IFNULL function.

Hello All,
We'll start a HANA project soon. Now We are communicating with vendors about SAP HANA Appliance.
We realised that SSD is not mandatory in HANA Appliance, because some of vendors give offer with only SAS disks, some gives with SSD disks.
I've searched for articles and SAP notes about SSD usage and found nothing?
Yes I know It's good to you SSD for log segment but I want to learn it's importance? Or is there any note/guide about using SSD?
thanks a lot,
regards

Dear Yuksel,
So, how do I display the sha1 hashed value for the password in the older versions?
Is it a combination of both BCODE and PASSCODE columns ?
Or do i have to execute another command to get what i am looking for ?
Cheers,
Deniz
For creating a Calculated Column that stores the power of a Measure we have to use the operator "**". For calculating the power to 1/n, you need to use the result of 1/n such as 0.5 for 1/2 or .25 for 1/4
So the expression is
CAGR_FIN**(.5)
If n in 1/n is stored in another column or calculated column then you can use
CAGR_FIN**(1/"COLUMN_NAME")
Attached a demo as well...
Make sure to give a DECIMAL data type (with the length and scale) and you would be able achieve your results.
PS: To add a note the expression editor accepts operators and functions that are listed in the bottom part and anything else will return an error.
Hi Juan,
Just to clarify, you have an issue with using wild card in input parameters, am I right in understanding this? Also is this on your Graphical Calculation View or Scripted Calculation View?
Hi Cote,
Is your variable checked as 'Is Mandatory'?, if so make it as unchecked and see data preview
Can I know which HANA version are you using?

Hello all,
I would like to know where I would start looking to check why on a restart would the the secondary master node take over from the primary master node?
So on restart Master Node (xxx-1) is taken by the secondary master node (xxx-2). Generally the master node must be the Primary Master, Unable to trgger loads when the secondary was acting as the master node.
Another restart solved the issue but if I want to give an RCA on this where would be the best place to start looking?
A presume nameserver traces at the time of the restart but is this config maintained anywhere? In relation to the assignment of the primary and secondary master nodes?
Thanks,
Michael
Hi,
Not sure if you're still looking at this, but we receive this question a lot from our customers - I tried to summarise the differences in this LinkedIn post, hope its useful ...
SAP Lumira: Ready to Rumble? | Paul Morgan | LinkedIn
HI Michael,
I see 2 questions in your message and here my response
1. Where would you check when there is a failover of master node?
I would suggest to check the NAMESERVER trace log on both XXX-1 and XXX-2 at the time of the issue. You should see a keyword FAILOVER right after the timestamp in the NameServer trace file that indicates all events related
2. Where is the configuration for the MASTER/STANDBY/WORKER setup maintained?
This setup is configured using the nameserver.ini on the OS, and typically seen as indicated below
/hana/shared/SID/global/hdb/custom/config/nameserver.ini
[landscape]
master: XXX-1: 30001 .....
worker: XXX-1....
active_master: XXX-1:30001
roles_XXX-2: worker
It can also be accessed using the HANA STUDIO-->CONFIGURATION-->nameserver.ini-->landscape
You can make changes on these configuration files and the next startup should follow the changes
it would be good if you can share your current status of this configuration to understand if you have any setting that is leading to an issue
Hope it helps, let me know if you have any questions

Hi Scott,
I have tested similar queries based on your example on our system that is SAP Certified and we have more than 15 tenants on it
My queries fetch more than 10,000 rows and it takes 100 ms-150 ms so it is definitely not an issue in the way the data is being queried, some thing very unique with your setup
Essentially SYS_DATABASES is a schema in the SYSTEMDB tenant so this query is definitely not trying to access the tenants underneath so it is not expected to take any more than a few 100 milli seconds
Hope it helps

One of our Big table JVSO1 has performance issue during delta merges. We have 4 HANA nodes ( 4th being standby ). We did the table partition and spread across three nodes. So we have one partition on Hana1 node, 1 on Hana 2 node and 2 on Hana 3 node.
Whenever there is a Delta merge occurring on Hana1 node, we see lot of performance issues. Sometimes DB connections from our SLT and ECC servers gets timed out. Also the Delta merge time is higher for no of records compared to same in other nodes.
We have 40 CPU Cores on this host with processing power 2400 MHz. Hana1 is our Master node. I see the CPU bumped up to 100% during this period of time. How does system calculates as how many threads it allocates to Delta Merge Process
How do we start troubleshooting this issue?
Mahesh Shetty
Hello Mahesh,
In order to be performed a Delta merge operation requires the whole table partition to be loaded into memory. If there's any column that is not fully into memory, disk read operations will have to kick in and get that column.
If the IO key figures of your host is not as in shape as the other hosts then it makes sense for it to perform worse on that particular host.
In that regard you can perform an IO Analysis and verify if the read operations are within the expected KPIs. See SAP Note 1999930 in that regard.
Queries "HANA_IO_Savepoints" and "HANA_IO_KeyFigures_Total" should be handy as well.
That's where I'd start looking.
BRs,

I followed your note and other relevant notes for I/O operations and also for save point durations. The note says "If the Critical Phase time" is more than 2 s repeatedly, then its I/O issue. I see some savepoints which are more than 2 Sec. I see 5-6 iterations in the span of 24 hours. Should I consider that as an I/O issue.
I checked Trigger Write Ration and Trigger Read ratio and they seems to be below 0.5 which means my I/O read/write seems to be correct.
I just had another Delta Merge Alert again on Another Node Hana 3 for table ZZJVA which took almost 1100 Sec for 1.5 M records. So I am assuming it is system wide issue.
I will try to open a message with SAP and see if they can help us with the issue.
