You cannot go to next Customizing level for data scope &1 --> long text

What causes this issue?

The scope of data key &V1& is used to define that <ZH>all</> material
ledger currencies/valuations are used.
IF &[SWITCH]S4H_DOCU_ON_PREMISE& = 'X'.
Going to the next Customizing maintenance screen to reduce the
currencies/valuations is not advisable for this scope of data key.
ENDIF.

System Response

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

How to fix this error?

IF &[SWITCH]S4H_DOCU_ON_PREMISE& = 'X'.
If you really want to reduce the currencies/valuations that are to be
saved, then assign to the valuation area a scope of data key that does
<ZH>not</> have the 'all currency and valuation types' indicator and
thereby allows you to reduce the currencies or valuations.
ENDIF.
IF &[SWITCH]S4H_DOCU_CLOUD& = 'X'.
Contact your system administrator.
