• Message number: 166

• Message text: &1 &2: Specifying a sample TDetObj is not allowed

What causes this issue?

DTFLD records you maintain for package 10020 are package-independent
and must consequently contain a <DS:DE.CNV_10020_DTOBJ_T_TEMPLATE>
sample target determination object</>.
DTFLD records you maintain for a package that may inherit any target
determination objects must also contain a sample target determination
object.
None of the cases described above applies to the current package &V1&.
Consequently, you must not enter a sample target determination object.
However sample target determination object &V4& has already been
stored.

How to fix this error?

Do not enter a sample target determination object.
