SAP Error Message - Details

• Message type: E = Error

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

• Message number: 159

• Message text: Material group &2 is not assigned to store &1

What causes this issue?

Store &V1& was not assigned to material group &V2&. Therefore the
system cannot determine whether the material prices include sales tax.
As the communication profile of the store also specifies that not all
material groups are sold, this data must be maintained.

System Response

The record for material &V3& cannot be maintained for POS - outbound.

How to fix this error?

Make 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, you must re-start
<DS:TRAN.WPMI>POS-outbound</>.
If the error occurs in change mode you do not have to take any further
action as the data will be retransmitted next time.
&NOTE&
If the communication profile of the store specifies that all material
groups are sold, this assignment does not have to be maintained. In
this case the system assumes that no sales tax is included in the
material prices.
However, if the assignment is maintained it is taken into
consideration.
