Hi ,
Conversion of legacy data into SAP can be uploaded using a standard SAP Tool called LSMW ( TCode:LSMW).
the below link gives a brief explanation of the LSMW tool
http://tutorialsap.com/abap/sap-lsmw-tutorial-with-steps-to-create.html
There are various methods to upload data within LSMW. If the number of records are very high like Article Master or Conditions for Retail the IDOC method must be used.
Standard IDocs
1. Article Master - ARTMAS
2. Conditions - COND_A
3. Source list - SRCLST
4. Customer Master or WRF3/WRF6 tables - DEBMAS
5. Vendor master- CREMAS
Etc. Use transaction code WE60 to see the structure of each of the idocs. New enhancements can be done for the idocs if the required field is not available.

Transfer data from legacy system to sap through rfc

There is an Excel-sheet where a user will enter some records, this excel-sheet should be automatically transferred to SAP. How it can be done? How can I see that records and how this link would be stablished?Give me the detail example! please help...!

hi,
You can write a program which will be run at scheduled intervals. You can crate a job for this.
This program will read the file either by OPEN DATASET, READ DATASET
for GUI_UPLOAD ... depending on where the file is located.
Then you can do the processing of each record using a BDC to insert recordsinto SAP. This will be done by doing a transaction recording in SHDB.

hi
kavitha
after getting records in internal table
use loop at stmt
between loop and end loop you need to clear
BDCDATA internal table (both header and body)
eg.
LOOP AT IT_MAT.
CLEAR BDCDATA.
CLEAR BDCDATA[].
perform bdc_dynpro      using 'SAPLMGMM' '0060'.
perform bdc_field       using 'BDC_CURSOR'

perform bdc_field       using 'BDC_OKCODE'
                              '/00'.
perform bdc_field       using 'RMMG1-MBRSH'

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 upload the data from legacy system database to SAP data base

Hi.
We are doing analysis of Legacy system and which needs to be converted to SAP system i.e. SAP implementation.
I just want to know , how we migrate the existing whole data( from legacy system) into SAP system.
and which method is the best method to use data migration from legacy to SAP system if data legacy data amount is huge.
Please suggest me.
Thanks.

Hi
We can either use the BDC or BAPI or LSMW or Direct Input techiniques for the data transfers.
The combination of both Session and Call transaction can be used to achieve this that includes the error handling also. This invloves the screen interaction.
These days, BAPIs are used to overvome some upgrade problems. For easy upgradation, we cna go for BAPIs. Here ther is no screen intercation.
LSMW mainly used for master data transfers using some standrad programs.
As per your client or company desicions we can choose any of them.
Please refer to these links for more understanding -

Upload Opening balance of G/L accounts from legacy system to SAP, and also

Hi Gurus,
How to upload Opening balance of G/L accounts from legacy system to SAP, and also Vendor and Customer balance.
My Doubt is when you upload the customer balance and vendor balance will it effect the sundry debtor account and sundry creditor account if not the how will the sundry debtor account and sundry creditor account will be posted with the balance. Please send me the general entry passed for posting the same.
What I understood is that when we are uploading the customer and vendor balances through LSMW, no entry will be passed and it will update the customer and vendor sub ledger in FBL1N and FBL5N but it will not affect the sundry debtor account and sundry creditor account.
To give effect to sundry debtor account and sundry creditor account we need to manually pass a journal entry as follows.
1) Sundry debtors account A/c -
DR
      TO clearing account A/c
2)     clearing account A/c -
dr
     Sundry creditor account A/c
Please let me know whether iam correct
Also please tell me what will be the scenario for uploading of the assets balances through LSMW.
THANKS AND REGARDS
