How To Fix ESH_OM_OBJ_MODEL_RP2873 - Model repository: The software component stack is corrupt

SAP Error Message - Details

• Message type: E = Error

• Message class: ESH_OM_OBJ_MODEL_RP2 - Object Model Repository (2)

• Message number: 873

• Message text: Model repository: The software component stack is corrupt

What causes this issue?

The software component stack of Enterprise Search is corrupt.

System Response

No connectors can be created for Enterprise Search models.

How to fix this error?

In case of a warning this means that the software component stack
contains unnecessary entries that are of not operational relevance but
can be removed if desired.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

An error may occur due to unfinished or erroneous software component
imports:
Check if all software components have been imported correctly:
You can use 'Actions' -> 'Import Log (Transport)' in the ES-Modeler to
view the import status.
Alternatively, report ESH_IEF_SNOTE__SHOW_IMPORT_ERR can be used for
analyzing the import errors. For example, if a GUID cannot be resolved,
you can check for SAP-notes by this GUID.
You can use report ESH_IEF_IMP_OM_UPDATE_CONTENT to retry the import.
Mind to set the flag 'Reset Imp. Log and Client-Copy', and flag 'Try
Import mult. times/ all SWC'. Usually, this will solve the problem.
An error may also occur after task list SAP_ESH_RESET has been run with
"Keep customer specific models" = X . Then there are two scenarios:
If you want to work with common runtime connectors run task list
SAP_ESH_SETUP_INITIAL_WRK_CLIENT.
If you want to run only CDS connectors the customer specific software
components are not necessary anymore and must be removed in this client.
In this case proceed as follows:
If you want to keep the customer specific software components:
Run task list SAP_ESH_SETUP_INITIAL_WRK_CLIENT again
Copy the software components to another client using the Enterprise
Search Modeler (transaction ESH_MODELER->Actions->Copy Software
Component)
Run SAP_ESH_RESET again with cleared flag "Keep customer specific
models"
If you do not want to keep these software components:
Run SAP_ESH_RESET again with cleared flag "Keep customer specific
models"
If the error persists, inform SAP.
