It is an Oracle command line tool that can be found $ORACLE_HOME/bin
I think that you don;t have coruption in your files, if you would have corruption in your datafiles Oracle would detect it when starting. But to be 100 % percent sure, please run dbv
It is hard to say how much time is need for this utility becaue it depends on speed of your disk, size of your datafiles. Please try running it on small datafile, and then you will get an answer for you question

Manage Dispute Case after data migration

Dear all,
Iu2019m facing the following problem.
Iu2019ve all the Dispute case in a Financial Supply Chain System (APJ).
Customer Line Items are, instead, in the Financial System (AP3)
After a Data Migration, all my line item will be migrated in to a new system (BD3) but without the Dispute Case.
There is a a way to link massively items with Dispute Case or users must proceed one by one ?
Thanks in advance
Alberto

sounds like changing the ALE from system 1 to the other system.
However I doubt it will be that easy.
I believe that could should contact SAP SLO to work out the best route for data migration.

Data Link after data migration

Hello All,
In a scenario during data migration from R/3 to Ecc. If we migrate the data related to orders, deliveries, invoices separately, how will we able to link these orders, deliveries and invoices after migration. As we will be giving new number ranges too for them.
Please advice.

Good Morning,
We create a filed in Template and links the column from the drop down List.

Lost book marks after data migration

Problems query data after data migration to Hana

Hi We currently have 2 BW environments: Release: 701 SP-Level: 0014 Support Package: SAPKW70114 DB: No Hana Release: 740 SP-Level: 0005 Support Package: SAPKW74005 DB: Hana It was necessary to migrate data cubes BW 701 -> BW 740, because in ECC only history of the last 18 months is maintained. After this migration, when I make a query in Query Designer and I use between in "Filters and Restrictions" no returned values, but if I include the value and not use the between the values are displayed. For example: I created a query with: one key figure, Comp_Code, Material and Fiscper. On filters and restrictions I informed that should return only the materials between 0001 and 0003. When running the query does not return values, but if I change the filter to only return materials 0001, 0002 and 0003, the query returns data. Note .: This problem occurs only with the migrated data from the BW 701, loads of ECC deltas are functioning normally. Could you help me solve this issue? Best Regards

Important point: I found that if you run the query in RSRT "Execute + Debug" button and do not use the option "Do not use SAP HANA / BWA Index (0)" the query runs without problems.
Additional Information:
- BW on Hana environment 740 is a new installation.
- To load the historical data for the BW on Hana was created an RFC with the BW 701, classic BW as source system to new BW HANA.
- BW 701 was generated Export Data Sources ( From cube to cube, from DSO to DSO) and we used of data sources to migrate historical data.
- Then BW on Hana is a new installation, but only the historical data were extracted from the BW 701 (no Hana)
- Export Data source generated on DSO data is ok, but the Data source of export from a cube, data is not ok. After data load this historical data, when I make a query in Query Designer and I use between in "Filters and Restrictions" no returned values, but if I include the value and not use the between the values are displayed, but the problem occurs only in the query on the Cube.
- Are there any recommended when historical data is extracted on the Cube by Export Data Source?

How to open mail on old PPC 10.5.8 after data migration to MBP?

Hi All, I have had a Mac 10.5.8 PPC (Leopard) for years, and recently got a shiny new MBP. After an Apple consultant migrated the data for me from the old to the new, I can no longer open mail on the 10.5.8 I can send email, and receive it, but I cannot open it. I still want to be able to use my old machine. Any suggestions appreciated.Thanks! (Everything on MBP is fine)

Keep all your e-mail on an IMAP account. That way both machines can check into it. MInd you, once you copy it to the local hard drive of the one machine, the other can't read it simultaneously.

Many problems after data migration

I recently installed an SSD on my Early 2011 MBP. I put my old drive in an enclosure and after installing Mavericks 10.9.4 on the new drive, I used Migration Assistant to copy over all my Users/Applications etc. Many problems ensued. One of the users migrated without any (major) problems. The other user had the following issues:
1) Every time I log in, several programs automatically open (Word, Powerpoint, Messages, Preview, Firefox). Even if I quit them all, log out and/or reset, then log back in, they all open back up again. This didn't happen before. None of these programs are in Users & Groups --> Login Items.
2) iCould, Facetime and Messages all ask my for me AppleID password, every time I log in. Facetime even asks for the password twice (I put it in correctly. If I put it in incorrectly it lets me know). It does this every time I log in.
3) Facetime and iMessage won't connect to the network. However, if I make a new user and sign in to Messages it works, so I know the network is fine.
4) Every time I start Firefox, it opens to the "recovery" page. I can delete the profile information, and it gets rid of this problem, but then I have no history/saved passwords etc. and that defeats the purpose of having my information migrated over.
I've googled the above issues and tried all the solutions I could find but nothing works. I'm fairly computer literate but this is causing me to pull my hair out! Any help would be appreciated. Thanks.

I resolved the problems above by using Linc Davis' post on Nov 23, 2013 11:44 AM on this thread: Could not sign in to iMessage.
Details copied again below
Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
This time you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.

After data migration CC Desktop is blank

I've just bought a new iMac and migrated my data from my old macbook. When I run Creative Cloud Desktop it shows a blank box. The gear icon only gives me the options Help, Open as Window or Quit. I've contacted support three times and they've had me run a cleanup tool, delete various files and directories in both /library/Application Support/Adobe and ~/library/Application Support/Adobe. Each time I was disconnected before the issue was resolved, twice while using Online Chat and once by phone. I'm starting to get a complex. Does anyone have any ideas how I can fix this?

Gmail not working after data migration

Migrated data from old (2010) macbookpro with maverics to "new" (2011) macbook pro with maverics and now gmail doesn´t work. The inbox is empty. Have tried to rebuild mail and restart computer. Both computers are updated. Gmail worked fine on old macbook pro with maverics. Have done migration from time machine to new computer (with backup from old computer). The "show in IMAP" setting in Gmail account is selected and I have tried to deselect and reselect it agian. Nothing I have tried works.
Any ideas?

I'm not. Have you tried posting in Gmail's forum area - http://www.google.com/support/forum/p/gmail?hl=en&utmsource=HC&utm_medium=leftnav&utmcampaign=gmail ?

Why is there no data on my new MacBook Pro after using Migration Assistant?

Last night I launched Migration Assistent between my MacBook to my MacBook Pro. It said it would take 12 hours so I left it over night. When it finished this morning it said that some files were not able to be transferred. But there is absolutely nothing on my new MacBook Pro. Why is that?
My TimeMachine backup disk has a cable that won't work with the new MacBook Pro so what other choice do I have to transfer data?

Data Migration for Open Purchase Order

Hi, All,
Is there anyone know how to Count the volume for Open Purchase Order. What's the normal strategy for the Data Migration and Cut-over stage?
My client want to know how many Open Purchase Order in the legacy system and then determine manual or automatic data migration. If manual, how to do? If automatic, how to do? Because all materials and vendors, plants are different number. How to track? How to find out to match between new and old?
Thank you very much

JC,
Sounds a bit early to be making decisions about the realization phase. It doesn't sound like you have finished the Blueprinting phase yet, much less the testing phase.
Anyhow, in my experience I typically use LSMW (Legacy system migration workbench) to load MM master data (material masters), Inventory (WIP, RM, FG, etc) Purchasing Master data (Vendors, Purchase Info Records, Source Lists, Quota Arrangements), and Purchasing transactional documents (POs, PurReqs, Scheduling Agreements, etc). Depending on the complexity and volume of data, it may be necessary to write custom programs to load the data. You will find this out during your requirements gathering.
It is uncommon but possible to load all of these data manually. I have never run across a client that wants to pay a consultant's hourly rate to sit at a terminal to peck away loading master data, so if the client intends to have his own users enter the data manually, the project manager should make provision that there will be qualified TRAINED client employees available for this data entry. I did help with a portion of a conversion once manually; of Sales Credits, but there were only about 30 SD docs to load. I did this the evening before go-live day, while I was waiting for some of my LSMW projects to complete in the background.
A good opportunity to 'practice' your data loads is right after you have completed your development and customization, and you have gotten the approval from the client to proceed from the pilot build to the full test environment. Once you have moved your workbench and customization into the client's test environment, but before integration testing, you can mass load all, or a substantial portion of your conversion data into the qual system. You can treat it like a dry run for go-live, and fine tune your processes, as well as your LSMW projects.
Yes, it is good practice to generate comparisons between legacy and SAP even if the client doesn't ask for it. For Purchase orders on the SAP side, you could use any of the standard SAP Purchasing reports, such as ME2W, ME2M, ME2C, ME2L, ME2N. If these reports do not meet the requirements of the client, you could write a query to display the loaded data, or have an ABAPer write a custom report.
You didn't ask, but you should also do comparisons of ALL loaded data - including master data.
It sounds like you are implying that the client wants YOU to extract the legacy data. For an SAP consultant, this is not very realistic (unless the legacy system is another SAP system). Most of us do not understand the workings of the myriad legacy systems. The client is usually expected to produce one or more legacy system technical experts for you to liase with. You normally negotiate with the technical expert about every facet of of the data migration. In addition, you will liase with business users, who will help you and the implementation team to logically validate that the final solution (turnkey SAP production system, fully loaded with data) will meet the client's business needs.
Finally, you mentioned how do you track the mapping of master data between legacy and SAP. There are many ways to do this. I normally try to get the legacy person do the conversion on his end, eg, when he gives you the load file, you would like to have already translated the master data and inserted the SAP relevant values into the file. If this is not possible, I usually use MS Access databases to maintain a master map, and I perform the mapping on a PC. If your data package is small, you can probably get by using MS Excel or similar.
Good Luck,

Data migration

Dear all my friends,
please help to share me about data migration before go-live FI system.
i plan to migrate GL acct balance, AP/AR open item and last 3 months historical data.
please help to show me : how should i do ?
thanks !

1. Normal GL Accounts: In this case line items are not required and totals are to be updated in SAP. This can be done using GL fast entry if the number is not too high.
2. Open Item Managed GL Accounts: All the open line items are required to be uploaded in SAP from Legacy in order to clear them. Hence, a LSMW / BDC program has to be developed to upload the line items.
BAPI_ACC_DOCUMENT_POST - for GL/AP/AR
BAPI_ACC_INVOICE_RECEIPT_POST - for AP
BAPI_ACC_GL_POSTING_POST - for GL
GL Balance
F-02 or RFBIBL00 or BAPI
Dr GL a/c Credit Data migration Account or Clearing Account
3. Customer & Vendor Open Items: All open line items in Customer and Vendor Accounts have to be brought in into SAP. For this also a LSMW / BDC program needs to be developed and upload the line items.
Vendor Balances
F-02 or RFBIBL00 or BAPI
Credit Vendor a/c (individually) and Dr Data migration Account or Clearing Account
Customer balances
F-02 or RFBIBL00 or BAPI
Dr Customers a/c (individually) and Dr Data migration Account or Clearing Account
4. Asset Accounting: In case asset accounting is implemented the individual balances of each asset (Gross Value and Accumulated Depreciation) have to be uploaded using transaction AS91. For this also you need to develop a LSMW / BDC program. Further, you also need to update the GL Accounts related to Asset Accounts with totals for each asset class T.Code OASV.
For uploading the Assets
AS91 -> for uploading assets in AA
OSAV --> for uploading assets in GL entry Dr Asset (individually) Cr Data migration Account or Clearing Account
You can use LSMW for uploading all these things
After uploading all, your data migration account will become zero

Data Migration from 11i to R12 Global - Open POs,lines, receipts & on hand upload, Is it possible to do the onhand qty upload with over riding of all receipts which uploaded against Open PO lines?

Hi Friends,
We are in a phase of data migration from 11i to R12
I was discussed with client & they wants extraction of all open POs which was generated after 01 Jan 2014 to till date in 11i.
Condition for open POs is PO qty-received qty=>0
critical Example for open PO is :PO no: 10 has 4 lines, 3lines full qty has been received & for 1 line partial qty(say 50 out of 100) received.
in this case he wants in R12 uploading as PO no:10 should entered as open PO with all 4lines & 3 lines complete receipt should be done, for 4th line partial qty i.e 50 should be received.
the question is if we upload on hand qty first, then open POs & receipts, it will increase the onhand qty in new system(mismatch of on hand qty's 11i to R12)
Is it possible to do the onhand qty upload with over riding of all receipts which uploaded against Open PO lines.
Or Please advice best solution.
Thanks & Regards

Data Migration from Legacy System in IS-U

Hi All,
We are going to Implement a new IS-U project, I have a problem with LSMW(Legacy System Migration Workbench ), I have some Conversion Objects of IS-U and I need to know whether Data Migration is possible or not, please tell me how to find these Objects and how to know Data Migration is possible or not.
Objects are like.,
1. Accounts
2. Actuate Reports
3. Business Partner Relationships
4. Active Campaigns/Campaign Content/Dispositions
5. Connection Object
6. Contacts
7. Contracts
8. Opportunities
9. Payment Arrangement History
10. Payments
11. Premises
12. Rate Changes
13. Security Deposits
these are few and there are some more..,
Thanks in Advance,
Sai.

Hi Ram,
Use Transaction Code EMIGALL. It will ask for company code. By default Company Code is SAP. If you entered with the SAP you will get all the objects.Then goto menu IS-U Migration-->User Handbook. It will give you details Idea.
Also Check the following Procedure
You can find detailed documentation of EMIGALL in SAP itself. Use Transaction EQ81 to display it. It provides all the concepts and procedures to work with EMIGALL.
Here are some points about EMIGALL :
1. It Migrates data Business Object wise
2. It uses Direct Input Technique
3. It has more than 100 objects of IS-U
and the steps for implementation goes like this:
1)You have to create a user specially for migration which will have all the authorizations related to migration workbench, BASIS and IS-U
2)You have to create your own company in EMIGALL. There is a default company called SAP.
3)Company SAP contains all the Business Objects
4)You have to figure out what business objects u need and then u have to copy those business objects to ur company from Standard Company SAP
5)Each objects contains more than one structure and each structure can contain more than one fields. The relation goes like this
Object ---> Structure ---> Field
6)You have to define field rules for each required field of the object. You have to mark "Not required" for fields u don't need
7)After field rules for a given object is set u have to generate load report i.e. actual Direct Input Program which will migrate data. This program is generated on basis of field rules set by u.
8)After the load report is generated u have to prepare an input file (import File) for migration. The import file should be according to structure provided by SAP and must be in binary format. SAP Provides the structure of file according to your configurations. You have to write ur own Data conversion program(in any language) for this task.
9)You take import file as input and migrate the data using generated load program
10)Finally u can check the Migration Statistics and Error Log
Thanks and Regards,
