This article explains how to permanently fix the posting of social insurance to account 336.
The first step is to check whether the company settings have the correct type of other liability and its posting set up.
Company - Settings - Modules - Employees - Insurance:
You can check the Document Type right here using the magnifying glass and change it. A separate way is via Accounting - Document Types - Other Liability Types - select the record and change it.
If the settings are correct and social insurance is still posted to account 321, check the relevant social security administration in the partner directory.
You can find out which social security administration is selected again in the company settings.
Company - Settings - Modules - Employees - Insurance:
You can access the partner's address via the magnifying glass and change it, or separately via Business Partners - Company Addresses.
Here, pay attention to whether the social security administration is assigned to the SUPPLIER group:
If so, right-click the field and select "Clear field"
The subsequent generation of liabilities will post the social security administration according to the Document Type you have preset.
