Next Number Maintenance fails to show right replaceable parameters

System: SAP ME 6.0.4.0

I am trying to define the numbering pattern for SFC in Next Number Maintenance (Number Type = Floor Stock Receipt). The online documentation describes the replaceable parameters that can be used as prefixes or suffixes.

If I use one of the following replaceable parameters:

%ITEM_GROUP_BO.(1)%

%ITEM_GROUP_BO.(2)%

%PARENT_SHOP_ORDER_BO.(1)%

%PARENT_SHOP_ORDER_BO.(2)%

%PRIORITY%

%SHOP_ORDER_BO.(2)%

%USER_BO.(1)%

%USER_BO.(2)%

ME fails to show me the right sample next number:

ITEM_GROUP_BO.(2)100014*

i configured the following:

Prefix: %ITEM_GROUP_BO.(2)%%ITEM_BO.(1)%

Suffix: %ITEM_BO.(2)%

Number Base: 10

Current Sequence: 14

Thanks for your help,

Markus
