Activate control indicator "All Currencies" (CO area &1 / FiscYr &2)

What causes this issue?

The 'All Currencies' indicator is inactive in CO area &v1& for fiscal
year &v2& (and possibly subsequent years).

System Response

Postings within CO are posted automatically also in the General Ledger.
The system always fills the field 'Document Currency', even if the
indicator 'All currencies' is not set.

How to fix this error?

Try to set the indicator 'All Currencies' for the next fiscal year (IMG
activity <DS:SIMG.SIMG_CFMENUORK3OKKP>Maintain Controlling Area</>):
If CO objects exist with validity periods that continue beyond the
current fiscal year (such as orders), the system will not allow you to
set this indicator, since this would cause inconsistencies. In this case
you cannot set the indicator. This is ok. Be aware that the system will
fill the field 'Document Currency' also despite the indicator is not
set. This system behaviour is different compared to releases before
S/4HANA.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
