In 2026, a configuration compatibility error is corrected based on the text of the 1C message: the compatibility mode is matched with the actual platform version, and the value suggested by the system is selected. The Tax Code of the Republic of Kazakhstan does not establish this technical procedure: Articles 214, 215 and 496 regulate joint activities and related invoices, while Article 723 governs the application of the special tax regime based on a simplified declaration (Articles 214, 215, 496, 723 of the Tax Code of the Republic of Kazakhstan).
What compatibility mode means in 1C
Compatibility mode is a technical configuration setting. It makes it possible to take into account the specific features of a particular version of the 1C:Enterprise platform. This mode may be required when a configuration is developed or customized on one platform version but run on another.
The problem occurs if the selected value is not supported by the installed platform or does not meet the configuration requirements. In this case, the program may stop launching and display a message stating that the compatibility mode is not supported.
If the error text provides options for correcting it, follow the wording given in the message:
- set the compatibility mode to “Do not use” if this is the value suggested for the platform version being used;
- select the version specified in the message if this option is available for the current configuration and development environment.
Compatibility mode is a technical property of the configuration. It should not be confused with a tax regime or tax accounting policy. For example, Article 723 of the Tax Code of the Republic of Kazakhstan establishes the conditions for applying the special tax regime based on a simplified declaration but does not regulate software compatibility settings (Article 723 of the Tax Code of the Republic of Kazakhstan).
Who may encounter the error
The message may appear in infobases running Kazakhstan-specific configurations, including accounting, payroll and trade management solutions. Because the technical check may be performed when the program starts, the user may see the error immediately upon launching the infobase.
For an accountant, this usually means that work in the infobase is temporarily unavailable. Technical parameters should only be changed independently if the appropriate permissions are available and the consequences are understood. An incorrectly selected mode may affect the configuration launch as well as the operation of customizations, extensions and data exchanges.
It is advisable to involve an administrator or developer in the check if:
- the configuration has been modified by developers;
- extensions or external integrations are used;
- the error appeared after the platform or configuration was updated;
- the same infobase is launched from different workstations;
- there is no up-to-date backup copy of the infobase.
The compatibility mode message itself does not confirm that the accounting data is corrupted. It indicates a technical discrepancy that must be compared against the platform version, configuration properties and operating conditions.
What to check before changing the setting
First, save the full text of the message or take a screenshot. Record the versions specified in it, the current mode value and the correction option suggested by the system. This information will be required if an administrator or developer changes the setting.
Then check the following in sequence:
- 1C:Enterprise platform version. Determine which platform version is actually used to launch the specific infobase. If a client-server deployment is used, compare the versions of the environment components.
- Current configuration compatibility mode. It is checked in the configuration properties using development tools, provided that the necessary access rights are available.
- Availability of customizations. Determine whether the configuration has been modified and whether the changes, extensions and integrations are designed for the previous platform version.
- Consistency across workstations. If the infobase works on one computer but does not launch on another, compare the platform versions and the methods used to connect to the infobase.
- When the error appeared. Determine which action caused the message to appear: a platform update, configuration update, infobase transfer or launch from another workstation.
Before changing the setting, create a backup copy of the infobase using the method intended for the applicable deployment option. In a client-server environment, backup and configuration changes should be coordinated with the administrator to avoid disrupting other users’ work or losing unsaved data.
How to resolve the error and verify the result
Open the configuration using development tools and locate the compatibility mode property. Select the value expressly specified in the 1C message: “Do not use” or the corresponding platform version. Before saving, make sure that the message applies specifically to this infobase and the platform version actually being used.
Do not select a value at random. If the actual environment differs from the expected one, first bring the platform versions on the workstations and server into alignment. For a customized configuration, additionally assess the compatibility of extensions, external data processors and data exchanges.
After changing the parameter, you must:
- save the configuration;
- apply the change to the infobase using the method provided in 1C;
- restart the program;
- make sure that it launches without the previous message;
- check the main operations, extensions and data exchanges, if they are used.
For an accounting infobase, additionally open the key accounting sections and make sure that documents and reports are available. In a payroll configuration, check the availability of HR and payroll documents, and in a trade configuration, check sales, receipt and inventory accounting operations. This check demonstrates that the infobase is operational after the technical change but does not replace verification of the accuracy of accounting data and reports.
If the message persists, provide the administrator or developer with its full text, the platform version number, the configuration name and version, the current compatibility mode value and information about the latest updates. Based on this information, the specialist will be able to reproduce the conditions under which the error occurred and determine whether the configuration property must be changed, the platform must be updated or the versions on the workstations must be aligned.
Questions and answers
Is the mode in 1C the organization’s tax regime? — In the context of this error, this refers to the technical compatibility mode between the configuration and the 1C:Enterprise platform. The special tax regime based on a simplified declaration is governed by separate conditions of the Tax Code of the Republic of Kazakhstan (Article 723 of the Tax Code of the Republic of Kazakhstan).
Can I select “Do not use” immediately? — Yes, if this value is expressly suggested in the message and corresponds to the platform version being used. If there are customizations, extensions and integrations, the change should first be coordinated with the administrator or developer.
Why did the error appear after an update? — The update may have changed the platform version actually being used or its relationship with the configured compatibility mode. The cause is determined from the full text of the message, the platform version, the configuration properties and the list of completed updates.
Do the accounting policy or tax settings need to be changed? — To resolve the message, technical configuration parameters are changed or the platform versions are aligned. The tax accounting policy governs the accounting for tax liabilities; for example, special rules for joint activities are provided for in Articles 214 and 215 of the Tax Code of the Republic of Kazakhstan (Articles 214, 215 of the Tax Code of the Republic of Kazakhstan).
What should I do if I do not have access to the configuration? — Provide the administrator or developer with the full error text, information about the platform version, and the name and version of the configuration being used. You should not attempt to bypass the established access restrictions yourself.
