How To Fix COM_IPC_API_CONFIG000 - No knowledge base could be found &1 &2 &3 &4

SAP Error Message - Details

• Message type: E = Error

• Message class: COM_IPC_API_CONFIG - Messages from the Configuration APIs

• Message number: 000

• Message text: No knowledge base could be found &1 &2 &3 &4

What causes this issue?

Processing a configurable product requires the existence of a set of
master data called a knowledge base. No knowledge base was found for the
given parameter logsys = &1, product_id = &2, product_type
= &3 and kb_date = &4.

System Response

The system terminates the processing of the product.

How to fix this error?

Perform the following checks to see if a knowledge base for your product
is available in the system:
1. Go to transaction se16.
2. Search for entries in table COMM_CFGOCLASS with object_name =
&2.
3. Note the KBID.
4. Search for entries in table COMM_CFGKB with the KBID from the
previous step.
5. Does the field logsys correspond to the &1?
6. Is the field fromdate less than or equal to &4?
7. Is the knowledge base released? Status = 0
8. Is the field active = 'T'?
Depending on the logical system of the product , there are two ways to
create knowledge bases . If the logical system is an ECC system, you
need to maintain the required master data for product configuration
(characteristics, classes, dependencies). You can do this with
transaction pme_vc. Then you need to create a knowledge base runtime
object out of this master data, using transaction cu34, and download
this runtime version to the CRM system via CRM Middleware.
If the logical system is a CRM system, you can create a knowledge base
from the product master in the "configuration models". Note that you
have to release knowledge bases by setting an appropriate status, and
activate changes with "apply changes".

Procedure for System Administrators

• What is the cause and solution for SAP error message COM_IPC_API_CONFIG000 - No knowledge base could be found &1 &2 &3 &4 ?

  The SAP error message COM_IPC_API_CONFIG000 with the description "No knowledge base could be found &1 &2 &3 &4" typically indicates that the system is unable to locate the specified knowledge base required for the IPC (Integrated Product Configuration) functionality. This can occur in scenarios where the IPC is used for product configuration, pricing, or other related processes.
  Causes:
  
  Missing Knowledge Base: The specified knowledge base may not exist in the system or may not be properly configured.
  Incorrect Configuration: The configuration settings for the IPC may be incorrect, leading to the inability to find the knowledge base.
  Transport Issues: If the knowledge base was recently transported from another system, there may have been issues during the transport process.
  Authorization Issues: The user may not have the necessary authorizations to access the knowledge base.
  System Errors: There could be underlying system errors or inconsistencies that are preventing the knowledge base from being accessed.
  
  Solutions:
  
  
  Check Knowledge Base Existence: Verify that the knowledge base specified in the error message exists in the system. You can do this by navigating to the relevant transaction codes (e.g., CT04 for class types) to check if the knowledge base is defined.
  
  
  Review Configuration: Ensure that the IPC configuration is correct. This includes checking the settings in the relevant customizing transactions (e.g., SPRO) to ensure that the knowledge base is properly linked to the IPC.
  
  
  Transport Verification: If the knowledge base was recently transported, check the transport logs for any errors. You may need to re-transport the knowledge base or manually create it if it was not transported correctly.
  
  
  Authorization Check: Ensure that the user has the necessary authorizations to access the knowledge base. You can check this in the user roles and profiles.
  
  
  System Logs: Review the system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the issue.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message. There may be patches or updates that resolve known issues.
  
  
  Contact SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP Support for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CT04 (Class Maintenance), SPRO (Customizing), and SM21 (System Log).
  Documentation: Review SAP documentation related to IPC and knowledge base configuration for more detailed guidance.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed.
  
  By following these steps, you should be able to diagnose and resolve the error related to the missing knowledge base in SAP IPC.
