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_INVOICE_RECEIPT_POST - for AP

BAPI_ACC_GL_POSTING_POST - for GL

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

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
