Import with work status settings

Question

I've recently set up work status settings for an application where we import data using a xls file and the standard Import package.
Even though I haven't locked any dimension members before, I get the following error message when importing data:
Logic Error of LOAD AND PROCESSError
Failed to commit transaction
1 errors writing data
Send through SendGovernor failed
I've tried restarting SendGoverner - did not solve the problem.
Any ideas on what might cause the error message?
We are on BPC 7.0 MS SP7.

Yes, I do use a transformation file and a conversion file.
Results of my latest testing:
1) Import file with 1 line, replace&clear and work status check selected - failed with this error message:
ISLOCKED::System error.;
The current members are locked::(ACTUAL, 2011.NOV, 1000)
However checked the table and it is clear
2) Import file with 1 line, merge and work status check selected - failed with the same error message as above.
3) Import file with1 line, replace&clear selected - work status check off: success
In which table would BPC maintain which dimension members are locked from a work status perspective? I haven't locked anything to date, perhaps it needs to be "initialized"?
