How To Fix CNV_20100388 - Table &1 is converted before table &2

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 388

• Message text: Table &1 is converted before table &2

What causes this issue?

You want to implement a country-specific chart of accounts. This means
that the previously operative chart of accounts is defined as a
country-specific chart of accounts in one or more of the participating
company codes after the conversion.
From a technical perspective, the settings and transaction data of the
old operative chart of accounts are transferred to the respective fields
for the country-specific chart of accounts during the conversion. This
is required for several tables and fields.

System Response

When you merge two or more old accounts into one target account in the
converted operative chart of accounts, only the data from one of the
original accounts in the fields for the country-specific chart of
accounts can be stored after the conversion.
To be able to do this filling consistently across all affected
country-specific tables and fields, the system needs to convert table
SKB1 first. During this conversion, the country-specific field
SKB1-ALTKT is filled according to above logic. All further
country-specific tables then refer to the result of the conversion of
table SKB1-ALTKT and enter the corresponding values into their
country-specific fields.
The required table sequence is set and displayed in this message.

• What is the cause and solution for SAP error message CNV_20100388 - Table &1 is converted before table &2 ?

  The SAP error message CNV_20100388 indicates that there is a problem with the order of table conversions during a data migration or conversion process. Specifically, it means that the system is trying to convert a table (denoted as &1) before another table (denoted as &2) that it depends on has been converted. This can lead to inconsistencies or errors in the data migration process.
  Cause:
  
  Dependency Issues: The tables involved have a dependency relationship, where the data in table &1 relies on data from table &2. If &1 is converted first, it may not have the correct or complete data it needs.
  Incorrect Configuration: The conversion sequence may not have been set up correctly in the migration or conversion tool, leading to tables being processed in the wrong order.
  Data Model Changes: Changes in the data model or schema that were not accounted for in the conversion logic can also lead to this error.
  
  Solution:
  
  Check Conversion Sequence: Review the conversion sequence defined in the migration tool or program. Ensure that the tables are listed in the correct order, with dependencies respected.
  Adjust Dependencies: If necessary, adjust the dependencies between the tables in the conversion logic to ensure that all required tables are converted before dependent tables.
  Re-run the Conversion: After making the necessary adjustments, re-run the conversion process to see if the error persists.
  Consult Documentation: Refer to the SAP documentation or notes related to the specific migration or conversion process you are using for any additional guidance or best practices.
  Contact SAP Support: If the issue cannot be resolved through the above steps, consider reaching out to SAP support for assistance, providing them with the details of the error and the context in which it occurred.
