I see a lot of people encountered error “Error obtaining concurrency lock (foreign_lock)” when running data package, even when sending data from EPM Add-in.  If you are on BPC on HANA, you may see the error “Database returned the SQL code 131. Error text: transaction rolled back by lock wait timeout: Lock timeout occurs while waiting RECORD_LOCK of mode EXCLUSIVE(TRANSACTION_ID=70,UPDATE_TRANSACTION_ID=325118715)

By searching SAP KBA/Note, you may get solution that increase value of RECLEVEL_NR to make it larger than another parameter PACKAGE_SIZE. Actually, this is wrong, make it even worse. (Therefore, this kba is not visible to customer, but you still can find it by Google. On other websites, see http://www.saptechies.com/runlogic-error-obtaining-concurrency-lock-foreignlock-bpc-n/ ).

Now, let’s see what RECLEVEL_NR means. Below is the description from BPC admin guide.

See what you found, the default value is 10. Not like what is mentioned in that KBA – it should be bigger than PACKAGE_SIZE(which is wrong). According to the description, the record-based locking will be performed if the number of the records is less or equal to the value you set. If you change RECLEVEL_NR larger(e.g. 42000) than package_size(which has default value 40000) , every time the data generated by your package or EPM Add-in nearly reaches to 42000, 42000 records locking will be performed on your BI server. If your BI server is not strong enough, the locking may fail to implement the lock.  As a result, you will see error “Error obtaining concurrency lock (foreign_lock)”.

So next time you see this error, you can try to change the value of RECLEVEL_NR to default value 10. To change the value, you can follow the steps below.

  1. Logon ABAP server.
  2. Execute transaction SPRO ->SAP reference IMG ->Planning and consolidation ->Configuration parameters ->Set model parameters
  3. Find Environment/Model.
  4. Edit parameter RECLEVEL_NR

By the way, changing the parameter doesn’t release the lock. It just prevents the lock issue from happening again. As an option, you can restart the BW server to release the lock.

If this error still persists, this error may be caused by product bugs. You can try to apply notes.

There are two KBAs as well regarding this error.

    Hi Charlie,

                I got the same issue which you had mentioned above. But the solution is different this issue may also occur when you are “DEBUGGING” the script logic in the ABAP level that is

    Reason For issue(Error obtaining concurrency lock (Foreign_Lock)):-

    •           If we are in “UJKT” for debugging purpose & if we are running the “DM Package” or “SEND DATA” for the same Environment & Model in EPM (Excel) which we mentioned in “UJKT” then this issue (Error obtaining concurrency lock (Foreign_Lock)) will occur.


    • Consultants who are facing this issue due to above reason can resolve it by just “Exiting” of “UJKT” .

      Hi Aravind,

      Those are 2 completely different cases: real locking and false locking. What you described – is real locking, i.e. 2 processes are trying to write same set of data. What Charlie was describing – is false locking, when it’s reported that locking happened, but it didn’t. And it can be a lot of cases why false locking happens. Charlie just described one of them; and I wish it would be that easy as setting RECLEVEL_NR = 10. User has to analyze why locking happened and then decide how to avoid it.

    Also if you get concurrency lock issues if you run DM packages at the same time users submit data, these notes may also alleviate concurrency lock (foreign_lock) issues:

    2193723 – Deadlock with RSPCSYNCLOCK & RSPCPROCESS

    2236636 – RSPCENQUEUE is locked always during Synchronous Execution

      Hi John,

      Does SAP BPC NW support multiple ‘locking attempts’ and ‘wait time’ functionality (as configured in RSPLSE expert mode) if the target data region is the same?

      e.g. When 2 users are planning data on the exact same data set. Or script logic is trying to write to the same target region?
