For table &V1&, at least one determination path with source
determination object OBJNR or OBJNRD and target determination object
&V2& has been stored in table CNV_10020_DTFLD (possibly as a subpath).
Because no analysis has been carried out for the table &V1&, it is not
clear which object types <zh>do not</> occur in this table and could
consequently be ignored during calculation of the memory requirements.

System Response

The system considers the memory requirements for <zh>all</> object
types, which means that the result is likely to be too high.
