• Message text: Object from invalid software component (&1, for package/dev. class &2):

What causes this issue?

The current delivery request &V3& contains modified objects from the
software component <ZH>&V1&</> (for package/development class <ZH>&V2&
</>).
These modifications cannot be delivered, since the software component
belongs to a layer for which no support is provided for creating CRTs in
the Software Delivery Composer.
As soon as one of the modified objects is delivered again with a Support
Package of the modified software component (<ZH>&V1&</>), you must
create a CRT (Conflict Resolution Transport) so that this Support
Package can be imported into the system where your add-on is installed.

System Response

The system displays the affected objects in the results overview of the
object list check.
If you have selected the option <LS>Additional modification information
</> in the results overview, under <LS>Settings -> Displayed
Categories/Options</>, the modified objects are further divided into
modification types. (See:
<DS:DT.TR_AUSL_HELP_CHK_MODIF_TYPES>Modification Types</>)

How to fix this error?

Check the delivery-relevance of the specified objects and remove all
objects that you do not need from the delivery request by selecting them
and choosing <LS>Correct Selected Entries</>.
<ZH>Note</>: If the objects in question are actually delivery-relevant,
contact the SAP hotline (using componenent XX-PROJ-AAK).
