SAP Error Message - Details

• Message type: E = Error

• Message class: WC - POS interface - outbound and Tickets & Additionals

• Message number: 161

• Message text: Material group & not assigned to store & for date &

What causes this issue?

The assignment of store &V1& to material group &V2& was not maintained
for date &V3&. As a result, the system cannot determine whether the
material prices contain sales tax.
As the communication profile for the store also specifies that sales
are not to be made for all material groups, this assignment is
mandatory.

System Response

The record concerned for material &V4& cannot be processed at POS -
interface outbound.

How to fix this error?

Maintain the assignment in <DS:SIMG.W_OE_EG_WL_0225.SIMG_OWER>plant
maintenance</>.
When the plant data is displayed, select 'Material groups'.
If the error occurs on initialization, restart <DS:TRAN.WPMI>POS -
interface outbound processing</>.
If the error occurs in change mode, you do not need to do anything, as
the data will be transferred again in the next transport.
&NOTE&
If the communication profile of the store specifies that sales are to
be carried out for all material groups, you do not have to enter this
assignment. The system assumes that the material prices do not contain
sales tax.
However, the system takes account of the assignment if it is entered.
