Clock in clock out corrections error

Hi;

We have implemented ESS/MSS.

We have employees from 4 companies accessing the portal.

Employees of 3 companies can do their clock in clock out corrections properly.But the employees of the 4th company get a dump when they click on the clock in clock out link.

The error is as follows:

The current application triggered atermination with a short dump,error key:RFC_ERROR_SYSTEM_FAILURE.

Can any one help us with this?
