• Message number: 095

• Message text: For field &1-&2 (to be converted), TDetObject &3 is not defined as such

What causes this issue?

For the field &V1&-&V2&, which is meant to be converted and is assigned
to the main source package number &V4&, determination by &V3& has been
defined at table level (field to be converted is empty). However &V3&
is not explicitly defined as a target determination object for the main
source package number &V4&.

System Response

The org. package acts as if an empty entry for the field to be
converted had been maintained in the table CNV_10020_DTFLD. That is,
<zh>no</> determination or delimitation takes place.

How to fix this error?

If you store a separate entry for the field &V1&-&V2&, this entry
overrules the entry at table level. Note that you may refer only to
target determination objects that have been defined for the main source
package number &V4&.
