Skip only Archiving data from ECC to HANA through SLT

March 9, 2015, 11:33 pm

Hello,

 

SLT is configured between ECC6 as source and HANA as target, real time replication is enabled. I have a situation, where I have to skip the replication for only those data which are deleted from the database after archived. But normal deletion process should replicate in HANA.

 

1st we are archiving some data in ECC6 and after archiving we are deleting those data or moving those data into content server. For this process those data also being deleted from HANA. How to restore those deleted archived data into HANA.

We cann't stop the server in the time of archiving.

 

Any help on this would be great help.

 

Thanks,

Replacement of SYSTEM user

Hi,

 

Generally, it is recommended that in HANA production system, not to use SYSTEM user "for regular day to day activity" and might be good idea to deactivate the SYSTEM user.

 

Now, if we want to create SLT configurations then we would need a super user like SYSTEM, so my question is how do we create the one which is replacement of SYSTEM user (also if I am not wrong, we cannot copy SYSTEM user as is), i mean we can create some technical user but how do we make sure it has all the required authorizations same as SYSTEM?

How to Replicate the same Table twice but in two different Target Tables

Hello Experts,

Is it possible to replicate the same Table twice but in two different Target HANA Tables ?

For example: There is a table: VBPA for which the replication is going on without any additional Transformation settings.

 

Now I would like to replicate this Table again to some other Target Table, let's say : VBPA_1.

 

Can we do so ?

 

If Yes, then how to achieve this ?

 

Thanks & regards,

Calculation jobs in SLT Replication

Dear All,

Could you please tell what is the importance of calculation jobs while defining a configuration in ltr.

If I define a total of 10 jobs, how many should go for calculation and how many should for data transfer.

 

Is it based on the size of the tables? If the tables have millions of records or is based on how many number of tables I set for replication and how many for load?

 

A detailed explaination of the importance of calculation jobs in LTR is highly appreciated.

 

Thanks & Regaards,

Vijay

Hi Experts,

 

Need urgent help on initial loading of cluster table BSEG.

Below are the statistics of my replication activity -

 

My SLT version is 2011_1_731 sp 5.

BSEG table level statistics-  176779953 records present


Jobs in SLT

DTL jobs - 5

Initial jobs - 4

Calculation jobs - 5

 

My calculation of 9 access plans ran fine but my initial load jobs started failing and in application logs with a structure mismatch clause.

Though in load statistics tab it shows some records read but it shows 0 records in HANA Studio.

 

Please find attached the error screenshots captured from my end.

Kindly suggest if there is any way to carry out any repairs and resume from loading directly if possible.

Several questions when system involved is upgraded/maintained

Hello all,

 

As per subject..

 

When the ECC source system is going to be upgraded/maintenance

  1. Steps before going to downtime

            Do we do just do LTRC, then 'stop configuration'?


     2. After the upgrade, how do I check which replicated table were modified/adjusted by the upgrade      

 

When the RS system is going to be upgraded/maintenance 

  1. Steps before going to downtime
  •      Do we do LTRC, then 'stop configuration'?
  •      ‘Stop configuration'  will just suspend the transfer of data from the source to the target, but the logging tables in the source system will keep filling?
  •       Anything      to watch out,  risk?

  

      2. After the upgrade/maintenance

  •       What is the best of way ‘resuming’ the replication, without flooding/impacting the source system? Any controlled fashion to follow?

 

Thanks in advance for your help/time.

 

Regards,

Terry

A CSV or flat file output

i have started reading the 2.5 version of the Applications Operations Guide which seems to be the most recent manual for the SLTRS and have been trying to find something about CSV or a flat file output. it seems the only replication targets that are available or planned are either an http connected HANA database and some kind of PI-driven output.

 

can someone confirm that neither CSV nor flat file output is possible in the current and future planned versions of SLTRS?

 

thank you,

Hi,

 

I have to create models on MARA and MARC and to use the same in ABAP in HANA but ABAP doesnt support varchar so to change the same to NVARCHAR for many fields.

 

Can someone please tell me how to change the data type at the time of replication only in SLT?

 

Any detailed document with step by step approach will be very much helpful.

1:N SLT replication configuration

March 25, 2015, 3:12 am

Hello Experts,

 

I am doing a configuration for 1:N SAP HANA replication to setup high available HANA in our environment.

My plan is to replication the tables from the same source ERP into 2 different HANA installations.

I have done the setup using the allow multiple usage flag for both of the configuration and the configurations were created successfully. My problem is that the 2 different mass transfer ID's are using the same logging table in the source system. In the configurations I used a dedicated tablespace where all the logging tables should be create and I was expecting to have 2 different logging tables for the same ERP table but that is not the case.

After successful initial load for VBAK R3 table into the 2 different schema, the delta load is happening only into one if the schema. So it seems if one of the configuration is performed the replication based on the logging table, the second is not doing anything.

 

Did anybody face similar issue? We are running on DMIS2010 SP10.

 

Thanks in advance for any help.

Replication not working after initial load to refresh QA system

March 25, 2015, 1:02 pm

Hi

 

I've recently restored the Source system(s) (ECC and CRM) from backups of Production. To refresh our QA HANA data, I stopped replication and  deleted the tables from both the ECC & CRM Schema's. Then from the SLT system's Data Provisioning, I started replication of the tables again.

 

The (12) CRM tables worked fine. But during the ECC table delete the HANA space completely filled up due to backups being stored in the same location as the executables. Long story short, eventually I had to Delete then recreate the entire schema and got the (73) ECC tables provisioned (using the Data Provisioning - Start Replication" option). But now a day after, they aren't replicating.

 

In the SLT system, in transaction LTRC:

     on the Expert Functions tab -> View unprocessed Logging Table Records,  there are Unprocessed Records on any of the tables that have changed

     on the Administration tab the configuration status is "Running"

     on the Table Overview tab, all of teh 73 tables have:

               Logging Tables have been created

               Current Action = Replication

               Table category = TRANSP

               LogTab created = X

               Triger State = Activated

     on the Expert Functions tab, I've:

               Reset Status for triggers and Logging tables

               Reset Load and Replication Status

               Reset Replication Object Definition

               Run the "Job Health Check" and found that "Although the master job is running, no active data jobs were found in the system"

               Run the "Table Health Check" and found "If migration objects are not defined or are generated at this point, the replication and data load is not possible."

                    FYI: Stopping the replication and reload & replicating the tables doesn't work. The error "Scheduled failed for action Stop Load / Replication" occurs.

 

In the transaction SM51 there are a lot of "Database error 416 at CON, user is locked; try again later: lock time is 1440 minutes" error's but the SLTADMIN user in HANA is not locked.

 

I tried to Stop replication of one of the existing tables from data provisioning in SLT, but that failed. I tried to start the replication of one of a new table from SLT, and it is sitting in the Table Over tab in a Scheduled Current Action, but has not made it over to HANA. I tried to "Replicate" the same table from HANA with "No results".

 

Although I do notice that the following RS_* tables have an Error Status:

          RS_LOG_FILES

          RS_MESSAGES

          RS_ORDER

          RS_ORDER_EXT

          RS_SCHEMA_MAP

 

Does anyone have any idea or helpful hints on how I can fix this situation?

We just did a proof of concept using DMIS_2011_SP8 replicating data from BW to an external Oracle DB and it went very well.  A few notes had to be applied, as mentionned in the general note, and we were up and running in 4 days, having tested replication both ways.  I was very impressed by the speed on a non Hana environment.

Hi,

 

I need to develop one report in which some sales tables line VBAK,VBAP etc needs to be moved from ABAP to HANA server.

 

I have couple of questions here.

 

a.) Regarding SLT configuration , will it be done by developers or BASIS will do the same?

 

b.) Now when I am clicking on Data provisioning, it says 'Data provisioning is not configured, contact system administrator', I am using one ABC user in HANA, and I think for this below roles are required.

 

 

SchemaName_DATA_PROV

SchemaName_POWER_USER

SchemaName_SELECT_USE

SchemaName_USER_ADMIN


So these will be provided by admin only means basis guys?

Replicate data from a view into HANA

Hello folks,

 

In our project, we have now reached a scenario wherein we need to replicate the output of a database view in ECC to HANA using SLT.

This is owing to the fact that the underlying tables that we are using for the database view are very huge; hence cannot be replicated as it is into HANA.

We are currently on SP09.

 

Kindly share your thoughts on whether it is achievable using SLT or not.

 

Best Regards,

SLT not working

SLT Replication is not working in our SLT Development system

 

We have re-configured SLT as the source system(NON-SAP SQL Server) has been moved from one server to another server.

 

As part of re-configuring we did the following things

 

1) Stop Master job
2) Delete triggers
3) Delete logging tables
4) Delete SLT configuration via LTR
5) Re-create the configuration via LTR.

 

After this we see the replication is in error status.

 

We see errors such as below

 


------------------------------------------------------------------
List of Error / Warnings on Tables
Error Table XXXXX not found in the control table DMC_MT_TABLES
Error Trigger XXXXX is not active (trigger status is 0-)
Error Trigger XXXXX does not exist in the source system
Error Migration object =Z__061;Defined? = No, Generated? = No (X
= Yes, blank = No)
Error System status indicates issues with the replication process
for table XXXXX
Error System status indicates issues with the load process for
table XXXXX
Error No access plan found for table
----------------------------------------------------------------------

 

The above errors repeat for all tables. I have attached snapshot for
your reference.

 

 

 

Source System: SQL Server (Non SAP)
SLT Server  Release - Netweaver 7.4 with DMIS 2011_1_731 SP 007.
HANA  :  (Revision 85).

 

 

I have already logged a call and wanted to post here also for any advise anyone might have.

Kalyan
