What is the issue?
Thinclient shows coding rows inccorrectly and session timeout errors may occur. This may happen if invoice has many coding rows (100+).
Resolution:
Increase maxRequestLength (default 4096kb)
- Open cmd.exe with "run as administrator"
- Run command: "%systemroot%\system32\inetsrv\AppCmd.exe" set config "Default Web Site/ThinClient" -section:system.web/httpRuntime /maxRequestLength:"10240"
- Check Thinclient web.config that it now contains the row <httpRuntime maxRequestLength="10240" />
- Restart IIS
