How To Fix SNHI_DELIVERY_UNIT091 - Skip undeployment of DU &1 (&2): partly migrated to HTA (see longtext)

SNHI_DELIVERY_UNIT091 - Overview

• Message type: E = Error

• Message class: SNHI_DELIVERY_UNIT -

• Message number: 091

• Message text: Skip undeployment of DU &1 (&2): partly migrated to HTA (see longtext)

System Response

The undeployment of SAP HANA delivery unit &V1& from vendor &V2& was
skipped because the transport method for at least one object of the
content was migrated from HANA Transport Container (HTC) to SAP HANA
Transport for ABAP (HTA).
Furthermore the system detected that the migration was only done partly
and requires further action.

How to fix this error?

Expand the log to the most detailed level. You can see all packages that
were already transported using HTA and the 'not yet migrated packages'
that require further action.
The recommended way to migrate from HTC to HTA is to migrate complete
delivery units as described in 'Migrating the Transport Method from HTC
to HTA' at http://help.sap.com/saphelp_nw74/helpdata/en/2d/881fd5e3c04a6
aaa9c6c740ffb30c9/frameset.htm. This was probably not done.
To finish migration from HTC to HTA you have following options for the
packages logged as 'Not yet migrated packages':
Migrate these packages (and their objects) to HTA and delete the HANA
transport container of the delivery unit &V1& from vendor &V2& using the
same transport request (recommended option)
if you do not want to migrate these packages (and their objects) to HTA
you have following options:
Unassign these packages from delivery unit &V1& from vendor &V2&, then
execute 'Take Snapshot and Save' for the HANA transport container of
this DU and use transaction SCTS_HTA to synchronize the changed
packages. Use the same transport request for both actions.
Caution: If you do not synchronize and transport the changed packages
together with the HTC, the objects of these packages will be deleted in
the target system when the HTC is imported.
Assign these packages to another delivery unit (new or existing DU) and
create a HANA transport container for the new DU or execute 'Take
Snapshot and Save' for an existing DU. Afterwards, delete the HANA
transport container of the delivery unit &V1& from vendor &V2&. Use the
same transport request for both actions.
Note: You must only migrate packages from HTC to HTA if you are the
content owner. Do not migrate packages that were delivered to you by
another content provider. Ask the content provider to provide correctly
migrated content.

SNHI_DELIVERY_UNIT091 - Details

• The SAP error message SNHI_DELIVERY_UNIT091 indicates that there is an issue with the undeployment of a Delivery Unit (DU) because it has been partially migrated to a High-Throughput Architecture (HTA). This typically occurs in the context of SAP HANA or SAP Cloud Platform environments where Delivery Units are used to manage the deployment of content.
  
  Cause:
  The error occurs when:
  
  A Delivery Unit is in a state where it cannot be fully undeployed because some of its components have already been migrated to a different architecture (HTA).
  The system detects that the Delivery Unit is only partially migrated, which prevents the complete undeployment process.
  
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check Migration Status: Verify the migration status of the Delivery Unit. You can do this by checking the relevant logs or using transaction codes that provide information about the Delivery Unit's state.
  
  
  Complete Migration: If the Delivery Unit is only partially migrated, you may
