Integration of CRM with legacy systems

Hi Experts,
We are planning to implement CRM on SAP Enterprise Portal. There are 2 non-SAP systems and one R/3 system in the system landscape at present, all to be connected to CRM which will be used as a front-end (with EP). Billing happens in the non-SAP system (Genesis?). Communication between non-SAP systems and CRM to be in XML.
Question:
Whether XI is required or whether it would suffice 2 use just CRM Middleware itself for the XML communication?
Any suggestions in this regard are highly appreciated
Regards,
Narayana

Hi Lakshmi Narayana,
For data transfer between SAP system and Non SAP(External System) .There are two options available.
1.Use CRM middleware with XIF adapter(External Interface)
2.Go for SAP Netweaver -XI (External Interface)
If you use CRM middleware middleware will carry the data in the form of Bdoc's(Business Documents)
<b>If use XI in the landscape:</b>
XI will converts the data into Idocs and push it to the FTP server,From FTP server external system will receive the data.
Allot Points if my post Helps!!!!!!!!.

How to call legacy system screen in web dynpro for java?

Now I'm using Netweaver CE for building BPM (Business Process Management).
In BPM system, I wana call legacy system screen(ERP, C/S , Web, etc..) in web dynpro.
I'v already known how to call legacy system method and data.( using RMI, SOAP and RFC )
But I don't konw how to call legacy system screen.
If there is no way calling legacy system screen, I will have to build every screen using web dynpro.
It's so terrible.
So I think there is a way calling legacy system screen.
It's just my opinion.
If It can call legacy system screen in web dynpro, please let me know how to call it.
Or, If there is no way calling legacy system, how solve I this problem?
Thank you reading my question.

I assume that with "legacy system screen" you mean ABAP Dynp sceens. Of cause it would be attractive to integrate into new BPM processes. However there is a conceptional issue: You could easily integrate them e.g. into a WebDypro using a URL to to the so-called WebGUI (the ITS that makes Dynp screens Web enabled).
However the Dynp screen store all there state in the ABAP backend. This information is not available to to the process engine, e.g. to set the Task to completed or to use the data in Output Mapping.
In fact you need a way to wrap the how UI transaction into a WebDynpro screen including data flow.

Item import to oracle inventory from legacy system

Hi,
We have a requirement where we need to import a very large number of items (close to 500,000) from a legacy system to oracle inventory.
We are using oracle open interface for this. We have designed a temp table for this purpose in order to validate data before moving it to the oracle interface tables. The data to be migrated is present in a separate data base and we need to move this data to Oracle temp table.
Can we use DB link to migrate this kind of data(in terms of volume)? Also what are the best practices that need to be followed while importing data to Oracle inventory? Is there any other way that this can be done?
Please share your thoughts and suggestions on this
Thanks
AM

Hi,
Some times DB link will fail, Please create custom package and try to interface with legacy system for periodically fetching the data into your tables. If the data is bulk please use API instead of Interface tables.
Thanks.

Trail balance with legacy balances problem

Hi Experts,
Need yours input for me on trail balance amounts mismatch with Legacy system.
My client using the both systems legacy and sap.
Now client taking the reports from legacy for the legal submissions for this year08-09.
I have done matching each GL with Legacy GL. Some of them were talied and rest of not talied.
this includes recon a/c also.
for the expenses accounts i can make JV postings, but the problem is how to make postings
to the recon accounts.(customers, vendors etc)
we are here having a huge transactions and client doesnt want to dig out all each and every.
client wants to make the JVs differed figure for account heads instead of dig all.
please let me know the easy way or t.codes to adjust the figures in various accounts for trail balance.
Regards,
Soma

Hi,
My sincere advise is not just to go by an easy way..
Understand where there is a gap and why there is a gap, vendor wise for AP and customer wise in AR..
Then try posting the difference amounts into these accounts as you have done in the first case..
This is a little time consuming job but thats the best way. Dont just post the differences as tommorow reconciliation would be a problem.

Exposing legacy-system's service using web services

Hi everybody,
     I have questions about how web services can be used with legacy system.
Let�s say I have a server serving stock data. The server is just POJO, it isn�t web module, doesn�t run on any J2EE container and client will request for data using my proprietary API which run over TCP/IP. My question is that what is the best practice or widely used pattern for exposing my stock service through web services.
     I�m not a web service expert so I think the easiest patter may be using web services as an adapter for my API. I�ll use jax-rpc to create web services StockWS.war and deploy it on a web server running on the same machine with my stock server. The web services will, in turn, internally use my proprietary API to request data.
I can see 2 problems in the above approach.
1. The need of web server. Administrator needs to start 2 processes; stock server and the web server containing StockWS.war. It would be great if I can get everything work in one process. Is there any framework or API that my stock server can internally use to intercept soap request over HTTP so that I don�t need a web server and everything is encapsulated in one process?
2. Performance. There will be my API sit between web services runtime layer and my stock server which may cause performance issue. If I can find a framework I�ve mentioned in problem1 then I can get rid of the API layer.
Please ignore my grammar mistakes.
Any suggestion is welcome, and if you have experiences integrating web services with your legacy system, feel free to share it here.
Thanks in advance.

Hi,
With regards to your statemetn "SDN downloaded document says to Generate Webservice URL through ABAP"   <- can you tell me more please? references/links/attachment?
As far as I am aware, that the type of web service required for integration it a 'normal' Netweaver Web app server web service.
There are limitations about the complexity of the WSDL - see Notes:
1653655 - Limitations in Web Service WSDL URL usage in Xcelsius 4.0
1703839 - Limitations of Web service usage in Xcelsius / Dashboard Design
also , changes between SAP versions requires reworking the WSDL
Note 1625091 - The WSDL URL for web service which generated in SAP Enterprise Central Component cannot be loaded into Xcelsius

Upgrade to SCCM 2012 R2: WinPE 5.0 and Legacy system.

Hi,
When upgrade to SCCM 2012 SP1 we get WinPE 4.0 boot images, and the PXE-boot did not working with CPU's that do not support NX/PAE/SSE2.
SCCM 2012 R2 need "ADK for Windows 8.1" with WinPE 5.0. I think it is same with WinPE 5.0 that it dont working with CPU's that do not support NX/PAE/SSE2.
Is there something else to considerations with WinPE 5.0 boot with Legacy systems?

I think the link you posted is broken, but this one works:

You can still use WinPE3.1, for those legacy computers:

However, we've had issues with other legacy systems and programs for outlook

I have a user who when she logs into her workstation and tries to access her outlook folders she is denied access. If she removes and then adds them back they work. Only one other person on our network had this problem which I initially thought was connectivity
related. I replaced their cat five cable and that seemed to solve their problem. I tried this with this user and it cleared up for about a week but happened again today. Any thoughts or experience with this. Outlook doesnt support archives in a network share
so I cant turn to them. It uses a login batch script to load mapped drives according to department. This all predates me so I did not build them. However, we've had issues with other legacy systems and programs so it is highly possible that this could be an
issue.

Will:Hi! Hi!
I use Firefox and it is now No. 1 on my choice of browsers. I agree it doesn't like the "for IE only" coded sites but then IE is now a non issue as it is dead in the water! So Safari is now really bloated and getting slower by the version. Firefox is quick, good to look at with numerous skins, and what is more has become the browser of choice for web developers on both platforms because it sticks to the WWC3 code. Camino is just another flavour of Netscape which seems to be a bloat AOL IE wannabee product. Do yourself a favour and download Firefox. Give it a few spins around the block and I'm sure you will agree. As for the sites it declines to accept because of bad code, then I would suggest a strong letter of protest to the webmaster! For too long IE has been flouting the rules and trying to be the only game in town. Take some affirmative action and let the webmasters know there are other browsers available to users. If you are still not a believer then check this out:

Stock Uploading with respect to Old Material Number of Legacy System

Hi Experts,
Need Your valuable Inputs,
As we are Going Go-Live in ECC6.0
As we have already Uploaded Material Master with the New Material Number (Internal Number Range generated by system ) Material Type, Valuation Class and Moving average indicator and related Fields in Material Master in ECC 6.0.with respect to old material number of Legacy system,
Now we need to Upload the Stocks and Values with respect to Old Material Number by Using 561 Movement Type in the New system of ECC 6.0 , This New material number and old material number Stock and its Values should match in the New ECC 6.0 .
As from the Old Legacy system we have only Old Material Number, Description and its stock, Value, How can we Upload the Stock with respect to Old Material Number ?
Kindly assist your Inputs.
Best Regards
Javeed Ahamed

you have to have a mapping from old number to new number.
you can either do it already in your source or you find the number in SAP itself with an ABAP command.
Usually the old material number is stored in field MARA-BISMT
if you want add the number in the source, assuming its Excel, then you you can download via SE16 from MARA just 2 fields: MATNR and BISMT. in Excel you can then use the formula VLOOKUP to get the MATNR by looking it up with old number.
if you are a little familiar with ABAP, and you load stocks by using LSMW, then you can easily get the new material number by adding an ABAP statement to find a material number by old number
select single MATNR from mara into wa_MATNR
where BISMT = oldmaterial.

User mapping certificate in UME (J2EE) with ABAP system as Backend (SNC)

I hope someone can help me with the user mapping concept (X.509 V3 certificates) for both "worlds" (ABAP and JAVA Stack).
I know how to install and configure certificate based (X.509) login to SAP ABAP and SAP JAVA (J2EE) Stack (--> enable encryption for communication and Single Sign On).
Situation:
We have a ready installed and configured X.509 certificate authentication environment for the ABAP world (between SAP GUI and SAP Server System)
and the user mapping was configured in the ABAP System (SU01). As the users are using certificates, the passwords are deactivated on the ABAP System.
Now if you want to integrate a JAVA (J2EE) Sytem and you want to configure the UME to the ABAP System (as Backend), you have an administrative effort problem with the user mapping (X.509) in the UME configuration.
1.) It is possible to assign manually the user public key to every user --> But to much effort
2.) As the user does not have a password (deactivated in the ABAP system), the way to combine the automatic mapping with a user login does not work.
3.) In the distinguished name of the user certificate there is no information about the SAP username itself
--> you are not able to use any information of the DN to bind a user in the Login Module configuration.
Now my question:
Is it possible to use the sncname information from the ABAP System (still configured and available) for the UME configuration?
As i know, it is possible to write an own Login Module. Does anybody has a customized Login module for this issue?
At the end the best solution would be to enable the same user mapping mechanism on the JAVA world as on the ABAP world. --> Mapping the Distinguished Name to the SAP User

We have developed a login module which is working with Kerberos auth, not x.509 auth, but still solves a very similar problem to the problem you are describing. As you know, when SNC is used to logon to ABAP stack, the SNC name of the user is mapped onto a SAP user via entries in the USRACL table. Our mapping login module takes the authenticated user principal name from the shared state and uses this to lookup the entry in USRACL table on ABAP stack, and from this it will know which SAP user to use, and can update shared state with this info so that CreateTicketLoginModule will created an SSO2 ticekt for the mapped SAP user id.
This means that mapping of users externally authetnicated identity onto SAP user/client can be managed in one place, e.g in ABAP stack using USRACL table entires and su01 t-code etc.
I know it is not exactly what you wanted, since you are looking to use x.509 certifiates instead of Kerberos authentication, but I thought it was worth sharing so that you know the concept has already been implemeneted many times. Many of our customers use this login module when they have our product, for the same reasons that you have stated.
Thanks,
Tim

Pull the data from legacy System into report and display with SAP data

Hi Friends,
My requirement is-
Create report by processing data from SAP tables and prepare output.And Before displaying the output, I have to pull the data from non-sap system which is readymade (It will come as flat file with similar fields as Report structure has) and finally display the records from both SAP and Legacy System by filtering duplicates.

Steps:-
Define the file path on selection screen:-
Selection screen data
    select-options   (s_)
      parameters     (p_)
      radio buttons (r_)
      checkboxes     (x_)
      pushbuttons    (b_)
SELECTION-SCREEN BEGIN OF BLOCK block1 WITH FRAME TITLE text-f01.
parameter:    p_file    type text_512 obligatory.
Start-of-selection.
data : l_fname type string. " File Name
l_fname = p_file .
call function 'GUI_UPLOAD'
    exporting
      filename                = l_fname
      filetype                = 'ASC'
      has_field_separator     = '#'
    tables
      data_tab                = lt_data
    exceptions
      file_open_error         = 1
      file_read_error         = 2
      no_batch                = 3
      gui_refuse_filetransfer = 4
      invalid_type            = 5
      no_authority            = 6
      unknown_error           = 7
      bad_data_format         = 8
      header_not_allowed      = 9
      separator_not_allowed   = 10
      header_too_long         = 11
      unknown_dp_error        = 12
      access_denied           = 13
      dp_out_of_memory        = 14
      disk_full               = 15
      dp_timeout              = 16
      others                  = 17.
if sy-subrc <> 0.
    message e000 with 'Unable to upload file from the PC'(t13).
endif.
lt_data is of same structure as the fields in the file.
For filtering duplicates:-
delete adjacent duplicates from lt_data.
Now display the records using either ALV or using write statements.
You can display the records in any of the way you want.

Help with data migration- Balances from legacy system for Loans Management

Hi all,
Can someone please help with this. I need help in how to go about migrating legacy data and balances for loans to SAP FS-CML.
Which flow types to use, and to do the migration.
Thanks.
Fisayo.

Hi Fisayo,
good documentation you can find in the transaction KCLJ
=> Help => Application help.
You also can find some documentation in the IMG:
=> Loans Management
=> Tools
    => External Data Transfer
      => Transfer Categories
         => Loans Master Data and Conditions
         => Loans Flow Data
You could use transaction KCLJ to upload the existing flows. For this you need a sender file with the flows you want to upload. This file you can create manually or by a report in the old/legacy system that writes the file in your file system.
The sender structure must be defined in transaction KCLL and you could use transaction KCLT to create or change a file to test the upload program.
You will also find some information in the online documentation.
Please be aware that the upload of flows must be tested very exactly. Iif you take over 'wrong' flows, this could cause serious problems in the future when you work with the contracts.
Best regards,
Tomislav

If SAP FICO as standalone system with other legacy system.

Hi All,
If SAP FICO as a standalone sytem with other legacy systems what is the impact on the SD module.
For eg: what we will miss or cant do the transcations with the SD perspective in SAP.
Thanks
ANGKS

Hi,
1. Yes all the dat needs to be copied
2. You can just assign the users in your orginazation structure to the profiles(Master data specialist, steward etc.) in BRF+
3. After copying the data to your standalone ECC 6.0 instance, all the process of data governance happens on your standalone system and once it is done you can replicate the data to your SAP 4.7 system. According to my experience, no functionalities will be missing.

Has anybody intergated eSourcing with a legacy system? any painpoints

has anybody intergated eSourcing with a legacy system? any painpoints

Thanks guys....I realize that 300 clip is considered torturous, but its rather depressing that my Q6600 main Vista PC can play it smoothly (or even booting it into...erm...Hackintosh mode), and there is apparently nothing I can do to get it working as well on my PPC Quad.
I guess its as much to blame on the decoder options; even XBMC (apparently the PPC best option for multicore) refuses to use more than 2 cores....never reaches 200% usage in activity monitor, yet still the stuttering/uneven play. It does play better than VLC & PerianQT tho.
Ahh well. Thanks for everyone's help....I may still yet upgrade the vidcard, but as of right now, if this wouldnt really help the 1080p issues, its less of a priority than before. Thanks for the GTX512 suggestion; I might go that route too.
Also, thanks to the guy who took the time to dl and test than 300 video for me, that helped immensely.

Data to be fetched from legacy system to SAP and doc needs to bee posted

Hi Experts,
I have a requirement where my client is using some application in Legacy system(Fuel Software) which receives fuel(Petrol, Deasel, CNG) in system and issue the same to company owned vehicles and wants that sap should be integrated and document also needs to be posted in sap for all the receivings and isssuences against their vehicles.
Process Designed is:
1. Required Data file will be picked from legacy system with some date stamp and will be placed in sap directory.
2. There will be batch job which will check for new file based on date stamp.
3. Will pick record n will pass to Goods_mvt_create bapi and then will post the document.
4. We have created Vehicles as Internal orders in sap and whenever any issue will be there internal order no will be captured.
5. By this way we are receiving and issuing in sap.
Now my problem is i am stuck in designing step 1 and rest 2,3,4,5 steps have already been designed and working fine. Need your help in step 1. Else you may suggest some better way-out but again want to mention rest steps are already mapped
Thanks in advance..

Hi Ashutosh,
You can use functions:
FTP_CLIENT_TO_R3
FTP_COMMAND
FTP_COMMAND_LIST
FTP_CONNECT
FTP_COPY
FTP_DISCONNECT
FTP_R3_TO_CLIENT
FTP_R3_TO_SERVER
FTP_SERVER_TO_R3
FTP_START_REG_SERVER
FTP_START_SAPFTP
FTP_STOP_REG_SERVER
FTP_VERSION
which allow you to connect from SAP ERP to any FTP server (if the legacy has it). You can validate the sample program RSFTP007.
