Posting Documents (Legacy Data Transfer)
Prerequisites
Before transferring legacy data from accounting documents, you should differentiate between accounts that are managed on an open item basis and those that are not.
Procedure
Select one of the following options for transferring document data:
Create a transfer account for the offsetting entry. This account should not be tax-relevant, that is, the Tax category field must not be filled in the master record.
Tax is calculated automatically during posting and is posted to the tax accounts. This occurs with postings to G/L accounts where the Tax category field is filled in the master record. Since you transfer the tax postings with the balance of the tax accounts, no new tax posting may be made when posting the documents or when transferring the account balances.
Example of the transfer of a customer open item
When transferring a customer open item, you post to the customer account, and make the offsetting entry to the transfer account. The system posts to the reconciliation account for goods and services automatically. You will already have transferred the tax posting along with the balances of the tax accounts.
When you make a payment with cash discount, the system automatically makes a tax adjustment during the payment clearing. To do this, it determines the required tax code from the G/L account items or the customer or vendor item if only one tax code was used in the document.
The offsetting entry for the documents is made to the transfer account when transferring legacy data. This account is not tax-relevant; the line item does not contain a tax code. Therefore, you must enter the tax code in the customer or vendor item when you transfer the open items. When all the postings have been made (including the special G/L transactions), the transfer account must have a zero balance. After this, you should block this account for posting.
Example of the transfer of customer and vendor open items using batch input
You transfer the open items from the customer and vendor accounts using batch input. The system automatically posts to the reconciliation accounts for receivables and payables. You post your special G/L transactions (such as down payments) manually. You also post the balances from the G/L accounts manually. You make offsetting entries to the transfer account for all the postings. After transferring the data, the transfer account has a zero balance.
You must carry out the advance return for tax on sales/purchases for the period you have just closed in your legacy system. If you have used the tax posting method described above, the G/L account items from the documents that have been transferred do not contain any tax information. It is therefore not possible to carry out the advance return for tax on sales/purchases for the closed period in the SAP System.
The customer and vendor items contain terms of payment and a baseline date for payment (for purposes of calculating the due date). You can transfer the terms of payment from the customer or vendor master record either using batch input or manually. To do this, you must enter a terms of payment key in the customer’s or vendor's master record.
However, if you post your documents using batch input, you should always manually enter the baseline date for payment, that is specifically for each individual posting.
