RSRV012 - Overview

• Message type: E = Error

• Message class: RSRV -

• Message number: 012

• Message text: Dimension &1 (technical name &2) is a line item dimension

<AB>Description</>
The dimension &V1& with technical name &V2& is also known as a <ZK>line
item dimension</>: In this dimension, just one characteristic is
accepted. In the InfoCube maintenance (transaction <AB>RSDCUBE</>), the
dimension is indicated as a <ZK>line item</>. There are no dimension
tables for a line item dimension, but rather a view for the <AB>SID</>
table for the characteristic in this dimension. In the fact table, the
<AB>SIDs </> for the characteristic are used instead of the dimension
key.
Therefore, the system checks all the <SID</>s that occur in a fact
table as well as in the SID table of the characteristic.
