I am having a muticompany environment. I create a user for the child company and then create an employee and assign it to related user. When the user fills the timesheet following error comes,

Integrity Error

The operation cannot be completed, probably due to the following:

    deletion: you may be trying to delete a record while other records still reference it
    creation/update: a mandatory field is not correctly set

[object with reference: general_account_id - general.account.id]

Please guide how to resolve it.
