we don't want correct those errors and these entries should be delated, could you please let me know are these errors can I see in any error table in SAP, is this facility is availbe in SAP or not?
becuase it isl very difficult to go and delete the entries one by one in sm35
Regards

Hi,
1) No updates will have been done for the items with errors.
2) Mark the Batch, then press F2 to call up the analysis. You can check here for the cause.
3) If you are not going to correct the items or the cause so as to post them, just delete the batch.
Kind regards

Migrate all Open Sales Orders From Legacy System (SAP) To SAP System using

Hi Experts,
             I've to Migrate all Open Sales Orders From Legacy System (SAP) To SAP System using Business Objects with a new SALES ORDER DOCUMENT NUMBER referencing the older one.
           I'll get all the required data with field in an excel file.
             Does any standard transaction exist for it ? Or how to go ahead with it ?
Thanks and regards,
Jyoti Shankar

Hi
If you are checking for CREATE option then Sales Doc Type
For more Info goto SWO1 transaction -> BUS2032 --> DIsplay --> Execute --> There SELECT the method which you want to perform... There you can fine the MANDATORY parameters also....
Or in DISPLAY mode PLACE Cursor on the Required Method and CLick the PARAMETERS button on toolbar...
That will show the MANDATORY parameters...
Reward if helpful....

Uploading data from a view in legacy system to SAP

Hi,
I am developing a custom table in sap. The data in this table will be loaded from a view which exists in the clients legacy system (Oracle db).There will be no middleware for the data transfer.
How can this be done in SAP? Can anybody provide a detailed procedure to do this?
Thanks in advance !!!!

Hi
Is the Legacy system capable of calling 'BAPI' or 'RFC'.
If yes, than you can create a RFC function module and with in the function module, you can write code to populate values to ZTABLE.
When the Legacy system calls the RFC with values, your Ztable will be updated

What is the diff b/w flat file and legacy system?

Hi everyone,
when v say v r working on scenario FILE to FILE? which format of file r v usually working on? and what is the diff b/w flat file and legacy system?
thanx

Hi,
<i>when v say v r working on scenario FILE to FILE? which format of file r v usually working on?</i>
>>>Many a times it will be a Flat file with CSV format,Tab delimited format, fixedlength fields.
<i>what is the diff b/w flat file and legacy system?</i>
>>>We can not differeniate like this..
Flat file may come from any systems, it may be live system or legacy system.
Legacy system- is something like old, or past one. If you talk about SAP , then older versions of SAP can be called as a legacy system.
So it may be a file system, or any system which is old version but it doesnot mean it is not in use,

hi jyothi ,
   there are lot of ways of doing it depending on data upload volume it will be decided .
1) thru abap bdc program which directly uses XL sheet data and creates SO using bapi/FMs.
2) using scat.functional consultant should be good enough to use this.
3)lsmw-laborious procedure but achievable.

Open Internal Orders from legacy system

Hi,
Is there a way to bring over open projects (Internal Orders) from legacy system into SAP?, especially the way to bring over legacy cost information collected on such projects.
Would appreciate any help,

Hi
As such you cannot do this. You download your Legacy system data to an excel sheet and then upload the PO details into SAP using an LSMW etc.

For creating/uploading the master data from legacy system to SAP we either use below options
1. BDC (recording)
2. BAPI
3. ALE iDoc.
I would sugguest you to use BAPI and there's already this post which explains few details about the BAPI:

IDOC/BAPI for Production order creation from Legacy system

Hi all
We are using an interface to create Production orders from legacy to SAP. Would you recommend an IDOC or a BAPI to create Production orders. If IDOC or BAPI then could you please mention which one?
thanks a bunch

Hi John,
For your purposes, please use BAPI for production order creation from legacy system. There is no standard inbound IDoc available to use. SAP has an IDoc for outbound interface only (message type LOIPRO).
If there is an inbound IDoc available, I would recommend to use an IDoc.
IDoc technology has excellent error handling and will allow you to reprocess an error (if any).
BAPI is also good approach to use and fast in term of processing.
For BAPI approach, you can use BAPI BAPI_PRODORD_CREATE.
Hope this will help.

Ferry Lianto

How to UNLOCK queues when data is migrated from legacy system to SAP syste

Hi All,
I need some help regarding queues (SMQ2). XI is been used to migrate data from legacy system to SAP system. Sometimes the queue is getting locked. Once the queue is unlocked then the message is processed correctly. So, the incoming queues must be "unlocked" routinely so that they can process through the system. There is a standard report RSQIWKEX available that can be scheduled in SAP system to automatically unlock the queues. Before using the standard report RSDIWKEX, we made sure that we have added parameter MONITOR QRFC_RESTART_ALLOWED set to "1" in Integration Engine specific configuration (TCODE SXMB_ADM).We are unable to analyze the reason for locking of queues and how to avoid it. If the locking of the queues can not be avoided, is there any way to unlock the queues? We tried executing this report but were not successful in unlocking the queues. Please guide us in solving this issue. It would be really helpful if you can give us a direction in solving this problem.
Thanks in Advance,
Shwetha.

Hi,
Just check if the Queues are registered in Transaction SMQR.
If its not, then register the Queue by pressing 'Register' Button

How to extract non-sap data (A/R Invoices from Legacy system) into SAP ICR

Hi
We are trying to bring A/R invoices from a legacy system into SAP ICR special ledger so that ICR tool can be used these items for intercompany reconcilliation. Could you please let's know the way to load these legacy AR invoice items into ICR data base using any function moduels.
Regards,
Eswar.

Hello Eswar,
In what form do you have these "external" open items? If they are contained in a file you should simply import the file in ICR during data selection using the File Upload functionality. There is no need to store them in a special purpose ledger first. Actually you would have to create a BADI implementation to extract the data from that special purpose ledger during data selection. Please consider using File Upload standard functionality.
If for some reason this cannot be used you could implement a logic calling RFC enabled function module FB_ICRC_ADD_DATA_RFC which will take the open items you are supplying in your logic and push them into the ICR database. This strategy could be used to include these external open items without them being processed during data selection.
Best regards,
Ralph

Data load from Legacy system to BW Server through BAPI

Requirements: We have different kind of legacy systems and SAP BW server. We want to load all legacy system data into SAP BW server using BAPI. Before loading we have to validate all data. If there are bad data, data missing we have to let the legacy system user/ operator knows to fix the data into their system with detail explanation. When it is fixed, we have to load the data again.
Load Scenario: We have two options to load data from legacy systems to BW Server.
1. We need to load data directly from legacy system to BW Server using BAPI program.
2. Legacy Systems data would be in workstations or flash drive as .txt (one line separated by comma) or .csv file. Need to load from .txt /.csv file to BW Server using BAPI program.
What we want in the BAPI program code?
It will Read / Retrieve data from text / csv file and will put into the Internal table. Internal table structure would be based on BAPI InfoObject structure.
Call BAPI InfoObject function module BAPI_IOBJ_CREATE to create InfoObject, include all necessary / default components, do the error check, load the data and return the status.
Could some one help me with the sample code please? I am new in ABAP / BAPI coding.
Is there any other better idea to load data from legacy system to BW server? BTW we are using BW 3.10. Is there any better option with BI 7.0 to resolve the issue? I appreciate your help.

my answers:
1. this is a scendario for a data push into SAP BW. You can only use SOAP-Based Transfer of Data.
http://help.sap.com/saphelp_nw04/helpdata/en/fd/8012403dbedd5fe10000000a155106/frameset.htm
(here for BW 3.5, but you'll find similar for 7.0)
In this scenario you'll have an RFC dinamically created for every Infosource you need to transfer data.
2. You can make a chain for each data load, so you can call the RFC "RSPC_API_CHAIN_START" to start the chain from external.
the second solution is more simply and available on every release.

Sergio
