Posting period locked; specify an alternative date [Message 131 – 107]

This issue happen randomly, so far happen to non superuser ID only, when the user create new service call, encounter error message 'Posting period locked; specify an alternative date [Message 131 – 107]', but the fact is the posting period is 'unlocked'.

Here's the scenario:

1. Non superuser id create new service call, when tried to add, encounters error message 'Posting period locked; specify an alternative date [Message 131 – 107]'.

2, Another non superuser id login to the same PC or different PC to try create new service call, also encounter the same error message 'Posting period locked; specify an alternative date [Message 131 – 107]'.

3. Superuser login whether to the same PC or differenct PC to create new service call, the service call can be added without error.

4. Susequently, the non superusers have no problem edit the service call.

Any idea what cause the issue? Is this a system bug?
