Preventing Errors 
Preventing Errors
The changeover package automatically corrects most of the errors that can arise during the translation to the euro. However, it cannot automatically correct all possible errors. Therefore, you should carry out certain steps before the changeover, in order to prevent as many errors as possible. By doing so, you can considerably reduce the amount of time needed for manual cleanup.
Preventing Errors Related to Postings
In the year of the changeover, you should make the minimum number of postings possible between the fiscal year change and the euro changeover. You should have as few postings as possible with an asset value date between these two dates. In addition, any postings you do make should be acquisition postings only. Other postings (such as, retirements or depreciation posting) can lead to situations that might require you to make manual corrections after the changeover. In many cases, you have to manually reverse the posting that caused the error.
The following postings do not cause problems:
Acquisition postings
Down payment postings
The following postings can cause errors under certain conditions:
The settlement of orders to assets can lead to errors when you try to reverse the settlement after the changeover, and if the only acquisition on the asset is from the settlement. In this case, the balance on the asset after the reversal could be negative.
The same applies to credit memos that you posted for their full amount to an order, and then settled to an asset after the changeover.
After the changeover: Do not reverse any settlements of CO objects to assets under construction, and do not settle any credit memos for their full amount (as far as possible).
Down payment clearings can lead to errors if you posted several partial clearings for one original down payment.
Before the changeover, post only complete clearings on assets.
Complete retirements and complete (intracompany) transfers can possibly cause inconsistencies between Asset Accounting and the General Ledger at document level. The system makes automatic corrections only at the account level.
Do not post retirements or transfers if at all possible.
Multiple write-ups in one document (that is, write-up to ordinary depreciation and special depreciation when the accounts are the same) can lead to inconsistencies at the document level. Multiple partial write-ups can result in the cumulative amount being exceeded.
Post write-ups by themselves and only for the full amount. Do not post several partial write-ups on one asset. The same applies to credit memos.
Avoid posting several partial transactions that add up to the total value.
Do not post partial transactions before the changeover.
Postings with a high probability of causing errors:
Due to the high volume of transfers that are involved in these transactions, the possibility of an error on the asset is very high. The probability of an error increases if several depreciation types were posted on the investment measure or the asset under construction, or if revaluation was calculated in certain depreciation areas.
Do not carry out the capitalization of assets under construction, or full settlement of investment measures until after the changeover.
Preventing Errors for Depreciation Posting
In order to reduce the amount of errors as much as possible, do not post any depreciation to the General Ledger in the changeover year before the changeover. Do not start the depreciation posting program in the changeover year until after the changeover. Post depreciation only after the changeover has been completed. To post depreciation to a past periods, open the posting periods in FI, and then start the depreciation posting run for each of these periods.
Preventing Errors for Investment Support
The cautions regarding the depreciation posting run also apply for claiming investment support. Do not post investment support in the phase before the changeover.
