• Message text: No object types can be excluded for table &1

What causes this issue?

For the table &V1&, relevant field &V2& and related source field/
object &V3&, a determination path with source determination object
OBJNR or OBJNRD and target determination object &V4& (possibly as a
subpath) was stored in table CNV_10020_DTFLD.
Because no analysis has been executed for this entry, it is not clear
which object types <zh>do not</> occur in the source field/ object and
can 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.
