How To Fix CNV_10020245 - For field &3-&4, source package &2, no TDetObject could be found

CNV_10020245 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 245

• Message text: For field &3-&4, source package &2, no TDetObject could be found

What causes this issue?

Assignment of determination paths to fields for conversion is only
possible if it the target of the determination is clear. Different
source packages may have different target determination objects
assigned. In package &V1&, field &V3&-&V4& has source package &V2&
assigned. However source package &V2& does not have an assignment to a
target determination object, or this assignment is not unique.

System Response

No determination path is assigned to field &V3&-&V4&.

How to fix this error?

The source package &V2& is probably defined as 'org.-independent',
which means that <zh>no</>determination or delimitation by the org.
package is needed (see also the hints below) and no action is required.
If determination and/or delimitation by the org. package is needed
after all, change the source package number that is assigned to the
field &V3&-&V4& (to be converted) accordingly.
&HINTS&
If the source package number is empty, no assignment has been made yet.
If the source package number is ???, field &V3&-&V4& occurs in more
than one source package. In this case, you have to specify the source
package that you want the org. determination to use.
If the source package number is filled, this package is assigned to
more than one higher-level package and consequently not unique.
<zh>For mere read-only fields, the source package number is not
relevant.</>
