GL Legacy Data Conversion

I have a question for the data conversion strategy.
We are planning to store 2 yr detailed transactions and 4yr balances in Oracle system. In terms of the data conversion process, we were also going to take the same method. It would, however, cause schedule and workload constraints. Actually, we have not yet discussed this from realistic view points. In other words, we do not insist on storing all of data which are 2yr transaction and 4yr balances.
Although I believe that we will be able to eliminate a volume of the data to be converted to new chart of accounts from old ones, I am a little bit concerned about a couple of things as follows:
1. the workload for reporting processes
Assuming that we will not use Oracle standard reports so much, it would not be a big issue, even if we do not convert all of data I mentioned above. We will store historical report data somewhere, and be able to generate certain reports using both Oracle data and historical data in the repository. If not, it could cause us extra efforts.
2. Audit trails / Examination trails
If we give up converting the data to fit new system, and that fiscal year has not been examined yet, how should we handle non-converted data for the examination? I am just wondering whether or not, we have only to prepare the conversion table, that ties Oracle balances back to ABC detailed transactions for their reference.
If anyone is are aware of anything you can advise me, could you please provide some information or guidance? Thanks to ALL.

Hi,
When you talk about GL-Data it is the trial balance to be loaded from legacy to oracle applications.
You can use Web-ADI to upload it ,the check list are
The balance for each account comibnation in the legacy system to be mapped to GL-Oracle code combination balance
With respect to open AR, AP Invoices if the invoices are converted using a control account for migration in GL then
the the balance transfered from AP,AR need not be reversed in GL from the source receivables and payables.
In case if the same account combination are for migrating the balances from AP,AR to GL ..Then the balances transferred from AP,AR should be reversed ..so that it does not affect the TB-GL-Balance
Finally ensure that the balance for the TB-tallys with your legacy system and upload it using Web-ADI ,import and
review and post it.
Hope this points helps your GL-Data conversion.

Data conversion rule manager & repository

Hi All,
We are running a fairly large legacy data conversion project from IMS and DB2 to Oracle which will involve quite a variety range of conversion/mapping rules (complex data manipulation to simple mapping). These requirement and rules involve both tech and business collaboration. Are there any data conversion rule managers tool out there that provide these type of capabilities:
1. Data conversion rule repository and version control
2. collaboration features (e.g. collaboration editing, commenting, decision capture, approval...etc)
We have check someed of the tools out there, and they are either generic requirement gathering tools, which is basically a few tabs with drop downs and a big text box, or some end-to-end data conversion automation solutions, which focus the execution of the data conversion instead of managing & tracking conversion rules.
Can anyone you help? please let me know if there is anything comes close that is practical and useful. Thank you.

Tubby, thank you for the info. Yes, we actually use ODI as a DEV tool for data conversion rule implementation and execution between our staging DB and target DB. However, ODI does not really have the capability to allow our tech and business to collaborate together and focus on "getting all these rules defined correctly". Having say that, ODI does have many very useful side features for our DEV to leverage and share information such as knowledge module and data mapping...etc
We would hope to have a practical data rule management tool & repository that allows tech and business to work together and gather all the rules and build up all the knowledge base in 1 single place. DEV/QA can then take away and focus on the implementation and validation.
Please let me know. Thank you very much.

GL Data Conversion from Legacy to Oracle EBS

Hi All,
I am tasked with converting legacy data into GL. I have worked on other conversions like supplier, AR and AP conversions but never worked on GL conversion, so I don't know how and where to start, what are the pre-requisites for entering data into gl_interface table how to ensure that data is correct in the .csv file etc.
Kindly request you all to guide me in right direction. Hope to hear from you all very soon!!! :)

Billing Legacy master & transactional data conversion/migration in SAP ISU

Hi Experts,
Please let me know, in ISU implementation project, what is Billing related Legacy master & transactional data conversion/migration is done in SAP ISU system.
Thanks in advance

Pankaj,
There is no straight forward transaction to download the Configuration data and export it to a file.
However, you can use the BC set functionality to extract the IMG node with its contents.
Check the following SAP help portal link for more info on BC sets
Business Configuration Sets (BC-CUS) - SAP Library
The archive data that you are talking about; Is it master data or transaction data?
Also, what this data is related to-Financial Documents, Billing related info?
There is one standard transaction SARA through which based on the migration object you can archive the data and export it into a file in a particular location..
Hope it helps..
Thanks,

Data conversion from legacy to SAP

Hi
I am put on covnersion of legacy data and given options to use the one of the following tools
LSMW
CATT
DTW
I am new to all this. I have to migrate the following data
GL Master
GL Open Balance
AP Master Data
AP Opn items
Fixed Asset Master
Fixed Asset Balance
Proft Centers Master Data
cost Center Data
Can youspecify which of the tools is most suitable for the conversion in each case?
please can anyone reply?
EMENEM

CATT is not a Data Uploading tool. It will work till 4.7EE.
You cannot see CATT after 4.7EE.
If the Data is bulk then Go for BDC (Batch data Communication) Else use LSMW (Legacy System Migratration Workbench)
again it Depends on your Requirement and your Perfectness.

Data Conversion in SAP E-Recruiting.

Hi SAP E-Recruiters,
Our client is using a Legacy application for recruiting candidates where it has 5000 candidates data base (internal and external candidates' applications).
Now they are asking for movement of this whole data to the newly implementing SAP E-recruiting system. We are exploring various data conversion methods and found that BDC, LSMW will not work for E-recruiting data upload as we have every thing in BSP/Web Dynpro pages here.
We need your help in finding a solution for moving this data from legacy to SAP E-Recruiting. Pls do the needful.
Thanks,
Sudheer

Sudheer,
So far there are no SAP delivered migration methods or BAPI's available conversion of candidates/applications, as you have already specified BDC's wouldnot work. Internal candidates always can be brought over in eRecruitment with integration techniques between PA and eRecruit depending upon the landscape.
However, for external candidates custom conversion programs have to be written by making use of methods/function modules that are used in BSP/WebDynpro.

Sridhar

Data conversion program

can u give idea about data conversion program for inventory management program stocks,which reads legacy extract file and the valuation master file from pc gets issue storage location valuation details and output a file with these details
regards,
phani

Hi Phani,
Make sure that the data from legacy system is stored in a TXT file in a specific format.
In SAP, create a program to upload the file using FM GUI_UPLOAD. The structure of the internal table will be same as that of the file.
Upload the data and update the necessary tables.

XI for new data conversion?

Hello experts,
You recommendations please on data conversion with XI versus using the LSMW tool?
We are working on a new implementation, planning to use XI for the interfaces anyway. Now the idea is to use XI for all dataconversion from the legacy systems.
Good idea, not suitable, better to use LSMW?
Your thoughts please!
Many thanks,
Albert

Hi again.
The response to this question cannot be a general answer, because it depends on several aspects. I'll try to order by importance.
1 - What kind of files do you have for material and BOM creation? XML files?
XI is a powerfull tool for transfer that kind of files. With an ABAP proxy, you can easily decompose a XML file into a strucuture in ABAP, so it's easy to import files. To send, is also easy. You fill a structure and XI will convert it to a XML file and sent to the respective receiver, using it's communication channel. So, if it's XML, I would say YES, use XI. If not, XI only can copy those flat files and that way it's not easy to get it's data in a proxy. You can copy those file to a directory and import files with a program, but, if so, why using XI for your purpose? Or you can do some mappings to convert flat file into XML file ... the mapping can be easy or very difficult.
2 - Experience in XI or LSMW? And Urgence?
This question is important. If you have experience in one of those tools, you should use it. As far as I can catch from your post, XI is a new tool for you, right? To master XI is a process that will take you some time ... not too much ... but consider this part too in your decision. However, since you will start using XI for interfaces, this could be a good start!
3 - Many other reasons can be found in the link that Murthy provided, but this two should be the most important (in my opinion).
Hope this helps.

Valter Oliveira.

Data conversion/loading

Our year end was on 31 March 2007 and since then lots of assets have been retired. The users will still have a display access on the Legacy system. Will the users be able to run their year end (31 March 2008) reporting on both systems should we decide not to take-over the assets that were retired after 31 March 2007.
I am busy doing data conversion/loading.

Hi,
I have dealt with this in the past. My recommendation is to ask the responsible financial person. He/she must decide what to do with the assets and its history, because it has a highly financial impact!

Please send detail steps for uploading legacy data

Hi friends,
please send detail steps for uploading legacy data
Thanking u in advance,
Diwa.

HI U CAN USE LSMW TO UPLOAD LEGACY DATA
LSMW is used for migrating data from a legacy system to SAP system, or from one SAP system to another.
Apart from standard batch/direct input and recordings, BAPI and IDocs are available as additional import methods for processing the legacy data.
The LSMW comprises the following main steps:
Read data (legacy data in spreadsheet tables and/or sequential files).
Convert data (from the source into the target format).
Import data (to the database used by the R/3 application.
But, before these steps, you need to perform following steps :
Define source structure : structure of data in the source file.
Define target structure : structure of SAP that receives data.
Field mapping: Mapping between the source and target structure with conversions, if any.
Specify file: location of the source file
Of all the methods used for data migration like BDC, LSMW , Call Transaction which one is used most of the time?
How is the decision made which method should be followed? What is the procedure followed for this analysis?
All the 3 methods are used to migrate data. Selection of these methods depends on the scenario, amount of data need to transfer. LSMW is a ready tool provided by SAP and you have to follow some 17 steps to migrate master data. While in BDCs Session method is the better choice because of some advantages over call transaction. But call transaction is also very useful to do immediate updation of small amout of data. (In call transaction developer has to handle errors).
SO Bottom line is make choice of these methods based of real time requirements.
These methods are chosen completely based on situation you are in. Direct input method is not available for all scenario, else, they are the simplest ones. In batch input method ,you need to do recording for the transaction concerned. Similarly, IDoc, and BAPI are there, and use of these need to be decided based on the requirement.
Try to go through the some material on these four methods, and implement them. You will then have a fair idea about when to use which.
LSMW Steps For Data Migration
How to develop a lsmw for data migration for va01 or xk01 transaction?
You can create lsmw for data migration as follows (using session method):
Example for xk01 (create vendor)
Initially there will be 20 steps but after processing 1 step it will reduced to 14 for session method.
1. TCode : LSMW.
2. Enter Project name, sub project name and object name.
    Execute.
3. Maintain object attributes.
    Execute
    select Batch Input recording
    goto->Recording overview
    create
    recording name.
    enter transaction code.
    start recording
    do recording as per ur choice.
    save + back.
    enter recording name in lsmw screen.
    save + back
Now there will be 14 steps.
2. MAINTAIN SOURCE STRUCTURES.
    Here you have to enter the name of internal table.
    display change
    create
    save + back
3. MAINTAIN SOURCE FIELDS.
    display change
    select structure
    source_fields->copy fields.

Legacy Data transfer Initial step?

Hi guys,
What is the first step that we need to do before transferring the assets from legacy data to SAP?
Is it setting up of the Chart of accounts? How do we do this.
what are the steps.
thanks
srik.

You have first to set up asset accounting. There is only a link with Chart of accounts when you set-up the g/l accounts for the asset postings.
For the conversion follow the steps in the IMG TC SPRO
Financial Accounting / Asset Accounting / Asset Data Transfer.
In the most cases an LSMW is create to do the asset upload with TC AS91. Manual the balance values are uploaded with TC OASV.
When you seach on this forum with AS91 and OASV you will found all information for different situation how to do the asset upload

Asset Legacy data transfer reconciliation with GL

We have recently merged a deactivated company code with our operating company and transferred all Finance processes, open items,master data etc.
We transferred assets using Legacy Data Transfer AB91 (we did not use intercompany asset transfer ABT1N).
We then transferred the Trial Balance.
The asset balances reconcile against the GL accounts for the transferred assets when executing S_ALR_87011964 and FS10N.
However there is a difference in ABST2 which is the same difference as the migrated assets.
I would expect there to be no difference between FI and AA for legacy data transfer
I have also run ABST for all affected GL accounts and there is no difference when executing this report.
Note that the company code migration occurred in January 2008, there is no effect on 2007 year end data.

Hi
You have to take over the GL balance using OASV t.code

Data conversion strategy for new SOB

Dear Viewers
on 11.5.10
We are creating a new SOB with a change in currency from Feb-11 as this is the requirement
For the same, we need to do data conversion.
I have a confusion for Purchase Orders and Sales Orders
Purchase Orders:
Open purchase orders will be converted, means the unfulfilled PO`s i.e the ones not received and are fully open.
The PO`s which have been recieved but not delivered, Requested the users to clear the intransit receipts.
The PO's which are partially received, what to be done for them?
If a PO is fully received and Delivered will not me converted to the new SOB as its not an open PO
but If invoice comes after Feb-11, than how the matching will be done?
What if a return has to be made moving forward in FEB-11 under new SOB
Sales Orders:
Open sales orders will be converted, that is the ones that have been entered and not yet booked.
Users have been requested to clear off the Sales order lines which are already pick confirmed but not yet shipped, hence they will be shipped and interfaced to AR
For the Sales orders that have been booked, those lines that are not yet processed further will also be converted.
Now what if a receipt comes after feb 11, how to handle this as the sales order wiould not have been converted?
Please give your advise on the data migration strategy for PO`s and SO's.
Please do add any point that may have been missed by me
Appreciate your help
Thanks
Emm

Hi David,
for master data conversion you can use LSMW and the RE-FX BAPIs. (please refer to SAP note [782947|https://service.sap.com/sap/support/notes/782947] ).
