[Problem description]
Controlling area 1000 has a controlling area currency of CNY. Company code 1000 has a base currency of CNY, while company code 3020 has a base currency of VND. After revaluing the prices for the CON2 activity at the end of the period, a tail difference balance was found in the production cost center of company code 3020 in the object currency of VND. How should this tail difference be adjusted?
[Problem Analysis]
1. After revaluing the cost center's CON2 activity price, a tail difference exists. This issue persists across all SAP versions.
2. When closing costs monthly, the first consideration is whether the production cost center object currency balance is zero. Secondly, the production cost center's controlling area currency balance is zero. In other words, the production cost center object currency tail difference balance should be adjusted to zero first.
[Solution]
1. The following steps can improve the accuracy of cost center activity prices:
1) When maintaining cost center activity prices using transaction code KP26, use a price unit of 1000 or 10000. Avoid using price unit 1 as shown below.
2）When calculating activity prices for production cost centers at the end of the period using transaction code KSII, you can improve the accuracy of activity prices by first setting the following:
Number of digits: The default is 6, and the maximum is 10. Entering 10 is recommended, meaning the activity price is accurate to 10 decimal places.
Independent Repeating Amount: Recommended. This means the activity price is calculated separately in the controlling area currency and the object currency. If not selected, the system defaults to calculating the activity price in the controlling area currency and then converts it to the object currency.
2. If, after increasing the activity price precision, there is still a balance remaining after revaluing the CON2 activity price at the end of the period, proceed as follows:
1) In transaction code RPC0, set the default currency for the CO report to the object currency.
2）Use transaction code S_ALR_87013611 to view the balance of the production cost center's object currency.
3) Use transaction code KB21N to enter the following information:
Instructions:
① Enter a small amount, such as 0.1 H
② Enter the currency: the target currency, in this example, VND
③ Enter the quantity and price, press Enter, and confirm whether the amount is the amount to be adjusted.
Alternative Adjustment Method: You can also use F-02 to transfer the production cost center expense balance from the FI module to the cost center debit.
3. Check the balance of the controlling area currency for the production cost center:
1) Use transaction code RPC0 to set the default currency for CO reports to the controlling area currency.
2) Use transaction code S_ALR_87013611 to check the balance of the controlling area currency for the production cost center.
3) If the object currency balance has been adjusted to zero, but there are balances in the controlling area, it is recommended not to process the balance. This will result in a balance of non-zero in the object currency. Because the object currency is equal to the company code currency, this will also result in a balance in manufacturing overhead/production costs in legal entity cost accounting, leading to an imbalance in the balance sheet or a discrepancy between retained earnings on the balance sheet and earnings on the income statement.
The following is the balance of the target currency (base currency VND) of 3020 Company: 0 balance.
The following is the control scope currency of 3020 Company (group currency CNY): those that are not 0 can be ignored.
