What causes this issue?

The <DS:DE.INV_FUNCTION_KK>invoicing function</> '&V1&' has been
recognized as not switchable with the standard setting "Not Active" in
accordance with the system configuration for the invoicing unit to be
processed (<DS:DE.INV_PROCESS_KK>invoicing process</> &V2&,
<DS:DE.INV_TYPE_KK>invoicing type</> &V3&,
<DS:DE.INV_CATEGORY_KK>invoicing category</> &V4&). The user has
activated the invoicing function for the simulation of the invoicing.
Note that the manual activation/deactivation of non-switchable invoicing
functions is only supported for the invoicing simulation; in update mode
for invoicing, you cannot manually activate these functions. The results
of the simulation will therefore generally be different to the results
of actual invoicing if you activate these functions.
