SAP S/4HANA Controlling Area Currency Type setup
This is in continuation of my previous currency blog SAP S/4HANA Currency Setup
Many time we get question that what should be our controlling area currency 10/ 20 or 30, in cases where Cross-company-code cost accounting is active.
Let us understand different options & their implications for this CO Area currency setting .
Case 1: The currency type of the controlling area (e.g. 30 = Group Currency) is also configured as parallel currency in FI (table T001A / tx OB22)
- Then KSL filled in all line items in all ledgers. The field is used as a common currency for FI and CO. It is called “Global currency for FI and CO”
- This is the recommended setting for all new installations.
Case 2: The currency type of the controlling area ( e.g. 20/30) is not configured as parallel currency in FI (table T001A / tx OB22)
- Then KSL is filled only in the leading ledger for CO relevant line items, i.e. line item assigned to a CO Object and a cost element.
- KSL is empty for all line items without CO relevance, i.e. balance sheet accounts or nonoperating expense or income.
- KSL is empty for non-leading ledgers.
Note :These above mentioned limitations of KSL update for CT 20 has been removed as of SAP S/4HANA 2020 for many of the scenarios. Would try to share the details about this as soon as I get some further insight.
Case 3: The currency type of the controlling is the local currency (currency type 10)
- KSL is filled with the same rules as in case 2.
- This means for CO relevant items KSL contains the same amount like HSL, and for non CO relevant line items KSL is empty.
In case 2 and 3 we say KSL is “used by CO only”. This settings are not recommended for new installations, but it is supported in order to be compatible with all existing currency configration of installed systems. Unfortunately it is not possible to automatically introduce a new currency in FI during the migration to SFIN or S/4H.
Reference SAP note 2231255
Universal journal (ACDOCA) integrates posting of Financial Accounting and Controlling.
The universal journal integrates postings of Financial Accounting (FI) and Controlling (CO). To be more specific, it unifies the general Ledger view of FI with CO. As a consequence, each journal entry contains the currency type of the controlling area, regardless of whether this currency type is defined as second or third local currency in FI. Each journal entry always contains the postings from CO.
If the currency type of the controlling area is defined as second or third local currency in FI, this currency type is filled not only in the general ledger view of the FI postings (table ACDOCA, field KSL) but also in the entry view (table BSEG, fields DMBE2 etc.). The controlling area currency is thus integrated with FI.
Having the currency type of the controlling area as second or third local currency in FI is the recommended setting , however if you have currency type 20 the same can not be assigned as FI currency for BSEG.
I hope this would help and comment in case need any further clarification.
