Client in 1C: Which Mode to Choose and How to Resolve a Startup Error

In 2026, to export a file, select the thin client if this mode is explicitly specified in the 1C message; first try the action again or restart the session to resolve the “Client parameters have not been initialized on the server” error. Choosing a 1C client is not the same as choosing a special tax regime: the procedure for choosing an STR is established separately and formalized by the prescribed notification (Article 716 of the Tax Code of the Republic of Kazakhstan).

What a Client Means in 1C

A client means the user-facing part of the system: it displays the infobase interface, sends commands to the server, and displays the results of their execution. The client is not a separate infobase or a standalone set of accounting data. Through it, the user works with documents, reports, directories, and the functions available to them in a specific configuration.

For an accountant, the difference between startup options is particularly noticeable when working with files. If a document has been generated in the database but cannot be saved to the computer, the connection method being used may be the cause. When the program or the instructions for the operation require switching to the thin client, close the current session, open the same infobase in the specified mode, and repeat the export.

This is a technical procedure for working with the program. It does not replace verification of the contents of source documents, tax registers, and reports. If the file is intended for filing a form or sending it to a counterparty, the accountant should monitor the deadline for the relevant operation: restarting the program and exporting the file again do not in themselves confirm that the document was sent on time.

When the Thin Client Is Required

The thin client should be used when required by the function being performed, a program message, or the procedure established by the organization for connecting to the infobase. If the file is not saved in the current mode, the sequence of actions may be as follows:

  1. Complete any unfinished operations and make sure that the required document has been saved in the database.
  2. Close the current 1C session.
  3. Launch the same infobase in the thin client.
  4. Generate and export the file again.
  5. Check whether the file has appeared in the selected folder and whether it opens.

Do not generate documents repeatedly without checking the result: duplicate files may appear in the folder, and the employee may send the wrong version. After a successful export, it is advisable to verify the file name, period, organization, and document contents.

If the thin client is already being used but the file is still not being saved, check the selected folder, the user’s write permissions for it, the session status, and the settings of the specific infobase in sequence. Command and section names vary depending on the configuration, version, and user permissions, so follow the interface of the installed program and the text of the message displayed.

How to Resolve the Client Parameter Error

When working in 1C, the following message may appear: “Client parameters have not been initialized on the server. To initialize them, repeat the action or restart the session.” This message indicates a problem while preparing the client session parameters. By itself, it does not mean that the accounting document has been completed incorrectly.

The technical error description may specify the ОбщийМодуль.СтандартныеПодсистемыСервер object, the ПараметрыКлиентаНаСервере procedure, and the Не ПриЗапуске condition. A user without development access should not modify the program code independently. First, perform the actions explicitly suggested by the system:

  • repeat the operation;
  • if the message appears again, end and restart the session;
  • after signing in, check whether the error recurs during the same operation;
  • record the database, user, and command after which the message appeared;
  • if the error recurs, provide this information to the specialist responsible for maintaining 1C.

A recurring message may be caused by the current session parameters or by data used by the program when performing a specific operation. It is impossible to identify a specific attribute based solely on the message text. Therefore, do not arbitrarily change the organization’s details, user settings, or general database parameters: such changes may affect other operations.

If the error occurs for only one employee, it is advisable to compare their permissions and user settings with those of an account for which the same operation is completed successfully. If several users see the message, the specialist should check the general infobase parameters and server-side processing. These observations will help determine whether the situation is associated with a specific user, workstation, or general database setting.

What the Accountant Should Check Before Contacting a Specialist

Before submitting a request, prepare a reproducible example. Specify the configuration and its release, the infobase, the user, the time when the message appeared, and the action after which the problem occurred. Attach the full error text and a screenshot if the company’s internal rules allow this to be done without disclosing confidential data.

For a file export problem, also record the file type and the actual result of the operation: the file is not generated, the program does not prompt you to select a save folder, an error message appears, or the generated file cannot be found. Also state whether the database was launched in the thin client and whether the operation was repeated after restarting the session.

Do not send the specialist your password, electronic signature, access keys, or working documents containing personal or financial data through an unsecured channel. For initial diagnostics, a screenshot of the message without sensitive information, the time when the error occurred, and the exact sequence of the user’s actions are usually sufficient.

After functionality has been restored, repeat the required operation and verify the substance of the result. For an accounting file, this means checking not only that the file exists, but also that the organization, period, amounts, and document status are correct. If the operation was performed several times because of the failure, check the list of created files and documents to prevent sending a duplicate or outdated version.

Questions and Answers

What is the 1C thin client? — It is an application through which the user connects to the infobase and works with the available functions. It should be used for exporting when required by the operation, a program message, or the established working procedure.

What should I do if 1C does not save a file? — First, save the document in the database, end the current session, open the same infobase in the thin client, and repeat the export. Then make sure that the file has been created in the selected folder, opens successfully, and contains the required data.

Do I need to contact a programmer immediately if a client parameter error occurs? — First, repeat the action or restart the session, as suggested by the message. If the error recurs, record its full text, the time when it appeared, and the operation performed, and then provide this information to the support specialist.

Can I modify the common module myself? — An accountant without the appropriate authority and qualifications should not modify the program code. The module and procedure names should be retained for diagnosis by a specialist, because arbitrary changes may affect the operation of the infobase.

Is choosing a 1C client related to choosing a tax regime in 2026? — No, these are different concepts. The client determines how the user works with the infobase, while a special tax regime is chosen in accordance with the procedure established for the taxpayer, including through the relevant notification (Article 716 of the Tax Code of the Republic of Kazakhstan).
