SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20900 - Message class for package CNV_20900

• Message number: 174

• Message text: Participating vendors have different Authorization Group (LFB1-BEGRU)

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

What causes this issue?

According to the mapping, you want to merge two or more old vendor
records into one target vendor record. However, not all the old records
have identical master data settings: It was found that old vendor
records have different 'Authorization Group'. (This is determined by the
indicator 'Authorization Group', field LFB1-BEGRU).
This may lead to inconsistencies in some applications related to target
vendor data.

System Response

<ZH>Error</>
From a technical perspective, this message can be ignored. This may make
sense in the following cases:
No postings to the respective vendor records have been made.
The respective vendor records are not used any longer and are meant to
be merged into a dummy record.

How to fix this error?

Analyze the situation, and either change the mapping so that only vendor
records with identical master data settings are merged or decide to
ignore the message because one of the special cases described above
applies.
If you decide to ignore the error even though none of the special cases
described above applies, consider that <ZH>the target vendor record
will get the Authorization Group of the old vendor record for which
priority the indicator is set. </>Make sure to evaluate the impact of
this decision - for example regarding potential inconsistencies and
required follow-up activities - <ZH>before</> you continue with the
conversion.

• What is the cause and solution for SAP error message CNV_20900174 - Participating vendors have different Authorization Group (LFB1-BEGRU) ?

  The SAP error message CNV_20900174 indicates that there is a mismatch in the Authorization Groups (LFB1-BEGRU) for participating vendors during a data migration or conversion process. This error typically arises in the context of data migration projects, especially when using tools like SAP S/4HANA Migration Cockpit or other data transfer methods.
  Cause:
  The error occurs when the system detects that the vendors being processed have different Authorization Groups assigned to them. Authorization Groups are used in SAP to control access to certain data and functions based on user roles. If the vendors involved in a transaction or migration do not share the same Authorization Group, the system will raise this error to prevent potential security issues or data integrity problems.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Vendors: Determine which vendors are causing the issue. You can do this by checking the vendor master data in the LFB1 table or using transaction codes like SE16 or SE11.
  
  
  Check Authorization Groups: Review the Authorization Groups assigned to the vendors. You can do this by looking at the field LFB1-BEGRU in the vendor master data.
  
  
  Standardize Authorization Groups: If possible, standardize the Authorization Groups for the vendors involved. This may involve:
  
  Changing the Authorization Group for one or more vendors to match the others.
  Creating a new Authorization Group that can be assigned to all relevant vendors.
  
  
  
  Data Migration Configuration: If you are using a data migration tool, ensure that the configuration allows for the handling of different Authorization Groups, if applicable.
  
  
  Consult Documentation: Review any relevant SAP documentation or notes related to the migration process you are using. There may be specific guidelines or best practices for handling Authorization Groups.
  
  
  Testing: After making changes, perform a test migration to ensure that the error is resolved and that the data is processed correctly.
  
  
  Related Information:
  
  Authorization Groups: These are defined in the SAP system and can be managed through transaction codes like OX03 (for defining authorization groups).
  Vendor Master Data: The vendor master data is stored in several tables, including LFA1 (General Data), LFB1 (Company Code Data), and LFM1 (Purchasing Data).
  Data Migration Tools: Familiarize yourself with the specific data migration tools and their configurations, as they may have options to handle such discrepancies.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or Security team, or reach out to SAP support for further assistance.
