SLT view replication

December 18, 2014, 7:53 am

Hi,

 

We have just updated our DMIS from SP4 to SP7 in order to replicate view as it is supported only from SP6. We are confused with the way how the view works. In LTRS, we created the filter settings for the view. Then tried to add the view in LTRC, but it gave the error "Table class VIEW of table /POSDW/V_AGGRTI is not supported for data provisioning" with the option 'Start Load' or 'Start Replication'. The underlying tables of the view already exists in the target schema in HANA. Then i tried the option 'Create Table or DB view'. It created the view in the hana database and then disappeared from the LTRC table overview. The view structure in HANA is not as per the filter settings, the view structure is same as the source system.

 

My questions are:-

1) Is Create Table or DB view is only option for adding view? whether other options like Initial Load or Replication will not work for it?

2) Why the view is not created as per the filter settings mentioned in LTRS

3) Why the view is not displayed in the Tables Overview? Is it correct behaviour?

4) What difference does it make if we create the view directly at the HANA database instead of using SLT?

hi,

 

there are few structure related table chnages on ERP side and due to which SLT replictaion is failing. Our target is Oracle system hence not sure apart from doing init load agian - any other fix settings in SLT that can be used? Though I can see that new field added in ERP - is reflected in SLT as well.Capture22.PNG

Question Regarding 1:N Replication Approach

Hi,

 

We are trying to setup SLT based replication to HANA system. In our environment due to few constraints we are planning to use one source system connected to two separate SLT server replicating data to two separate HANA systems. Following is the high level view.

 

1 source --> 2 SLT --> 2 HANA

 

As per the guide 1:N SLT replication approach is supported however guide doesn’t explain whether it allows multiple SLT in between 1:N or not.

 

I have question regarding this setup.

 

1> Is the following approach supported?

 

1 source --> 2 SLT --> 2 HANA

 

 

2> If we have 2 SLT system connected to single source system then for any single table in source system, will there be two triggers for same table OR single trigger will feed both SLTs?

 

Thanks

Using SLT Replication Server for non-SAP Target

Does the SLT Replication Server Support a non-SAP Target, for example ECC -> SLT -> Operational Data Cache?

 

Based on the literature I have read, it seems to indicate that this is possible.  We are looking for a solution to provide real-time replication from an SAP environment to a data cache.

 

Has anyone out there configured this type of architectural scenario?

SLT During Source and Target System refresh

January 18, 2016, 10:43 am

I am trying to understand the correct handling of SLT during a refresh of a source ECC and target HANA system. I have read through the document titled "Resuming Replication Without Initial Load After System Refresh or OS/DB

Migration" but still have a couple of clarification questions.

1.) It states that all delta data has to be replicated prior to the system copy being taken. Does this mean no user or batch activity is allowed on the source system since that could create further delta data and hence the source system has to be under maintenance?

2.) Does the SLT configuration need to be disabled in the production SLT system prior to the source and target system copy or only in the QA SLT system?

3.) There is an additional step to be performed if the HANA Data Provisioning UI is being used. The table RS_REPLICATION_COMPONENTS needs to be adapted for source and target. Is there a way to simply disable the data provisioning UI in HANA to begin with so it cannot be used? If not, does it just mean if that table is not maintained after refresh replication still works but the HANA UI can no longer be used?

Dear Team,

 

We are using ECC and NW 7.4 on Sybase 16 with windows server 2012

Hence we cannot use SRS since it doesn't support Sybase 16 and windows 2012

 

what are the other methods available to replicate logs to DR kindly suggest

Table stuck on initial load in SLT

We have our biggest table KONV 1,8 Billion records that has finished loading in the initial load phase in SLT replication.

But it has finished 48 hours ago and is still in status replication (Initial load), records are being logged as I can see them using unprocessed records function. It appears in process in the data transfer monitor but there is no movment in our target database.

Reading was set to type 5 for initial load and then reste to original type 3 after the initial load finished

Runtime objects have been generated.

 

Any one have any ideas on how we can get the table to go into replication mode?

Sensitive Data on Table

Hi All

 

We are on SP8 - I want to load a table from sap to hana using slt and the table have sensitive data in one column ..I can drop the column but unfortunately the column is a part of key and if i drop i can't maintain the integrity of the records as  this  would be duplicate  the records without the sensitive info column ..

 

I was thinking of scrambling the data but i was not sure how it works if the record is an update

Can SLT replicate data directly to Hadoop

November 9, 2014, 11:02 pm

Hi,

Has anyone successfully connected SAP SLT directly to Hadoop or other big data services where the big data is the target? We have a scenario where our SAP OER will produce millions of records of which we wish to report against but see that the scale, ie number of records plus the data retention requirements will mean a typical SAP BW and or a SAP HANA will not be a viable architecture.

So is SLT a contender, excluding potential license discussions?

 

Thanks

Rules in SLT during replication

We are replicating VBAK and VBAP from ECC to HANA, I'm aware we can filter the records using the rules based on certain fields in SLT.

But i want to know is it possible to filter item records(VBAP) based on a field in Header Record(VBAK) in SLT. If so how we can do it?

 

Thanks for your Help.

SLT and HANA deleting archived data

July 8, 2013, 7:45 am
$

From the SLT Operations Guide, section 5.2 I can see the following statement

 

5.2 Archiving Data in Source Systems

The trigger-based replication also considers the deletion in source tables by archive activities (since it is not possible to distinguish on the database level between delete actions cause by archiving versus regular deletion of data records). As a consequence, SAP LT Replication Server will also replicate archiving activities as delete actions in the SAP HANA database.

 

In a typical standalone/sidecar implementation of SAP HANA, I would assume that in most cases this is not favorable behavior or a desired function. In typical DW/DataMart implementations, the data should be persisted in the target even after the source system data may have been archived. I can refer back to how BW operates in this caes - any new/changed data is extracted to BW, but any archiving operations do not affect the already extracted data in the target system.

 

I know there is functionality available to load archived data into HANA, but that would seem like a troublsome method to 'put the pieces back together' and get a wholistic picture of all the historical data (online data + archived objects) and would present some interesting challenges in the target (HANA).

 

Is there any way to disable the functionality to replicate deleted data due to archiving? Is there anyone with some experience navigating around this hurdle in a standalone/sidecar scenario that can shed some light as to how they handled this?

 

Thanks,

Justin

Two SLT configuration from client 010 & 020

Hi All - I have two SLT configurations SRMDB and SUSDB. SRMDB is sourcing from client 010 SRM and SUSDB is sourcing from client 020. We are in DMIS 2011_1_700 SP 0009.

 

Problem: Table BUT000 is replicated in both configurations but there is only 1 trigger showing in the source system (I used SFSRFW_DROP_TRIGGER to view the source).

 

For example, I would replicate BUT000 in SUSDB first. The trigger source code shows the client 020 for MANDT. I would insert records into the table and replication would be OK. Then, I would replicate BUT000 in SRMDB. The trigger source code shows the client 010 for MANDT. At this point, it overwrote it. I would insert records in SUSDB BUT000 and nothing would show up in the source logging table therefore they would not go to HANA.

 

Does anyone have any tips?

 

Thanks in advance.

How to use filter option in initial load for huge tables

Hi Gurus,

 

We are replicating from ECC to HANA with LTRS only initial load.

I encountered some problems, would need your expertise on this.

  • How we can use filter/selection criteria in table. example: KNB1, I want to send only for 5 company codes?
  • How we can change the target table name. like KNB1 should go to ZKNB1?
  • Can we use same DB user for replication to different schemas in same database?
  • How we can handle VBAP, BSEG like huge tables.

SLT replicaiton from ECC to HANA -> problem with replication of append structure in customized table

Hello all,

 

we are replicating data from ECC into HANA with SLT and are facing a problem with append structure of a customized table in ECC. There are data fields with data type DEC and CHAR in this append structure of the customized table. The whole table structure with the append structure could be replicated without any problem. The data fields with data type DEC in the append structure could also be replicated into HANA, but the data fields with data type CHAR is not working. Any hints are welcome Thanks a lot!

Is it possible to transfer logistics transaction data (like sales order , purchase order ,, etc ) from ERP to S/4 ?

Hi all,

 

I know that ERP - S-FIN scenario , SLT transfers transaction data and financila BAPI is called on target S-FIN system. Finally transaction data is stored in S-FIN.

 

My question is How about ERP(Non HANA) - S/4 enterprise(logistics) scenario ?

Since upgrading ERP(Non HANA) to S/4 is little bit premature,  I want to transfer logistics transaction data from ERP to S/4 and want to use S/4 as a real time reporting platform.

Is it possible to transfer logistics transaction data( like sales order , purchase order ,,,etc ) from ERP to S/4 using SLT ?

No data from ECC by SLT to ADSO in BW HANA when using Infosource

Hello,

 

I have the following dataflow : table EBAN from ECC extracted by SLT to an ADSO in BW HANA.

 

When I use a transformation from the BW datasource to the ADSO, no troubles. When I insert an Infosource between the datasource and the ADSO, no data are extracted anymore.

 

I need this Infosource as we have several ECCs those data will merge into a single ADSO. Maintenance of the common BW flows/rules will be then much easier help to the Infosource.

 

SLT 2011_1_731 SP 0008

BW 7.4 SP 0011

ECC 6.0

 

Many thanks for your help,

Laurent
