Checkbook Currently In Use Error Message

When you start a check run and receive the error message: Checkbook is Currently IN USE by User - Horizon Program, this means the listed user has started a check run for the same checkbook in the program listed.

When a user starts a check run, the Horizon system locks that checkbook for exclusive use by that user.  No other user can start a check run for that checkbook until the first user completes (posts) or cancels the check run.

Please note, an active check run for a different checkbook will not prevent a check run for another checkbook. The error will only appear when attempting to access the same checkbook as another active check run.

Closing the program does not unlock the checkbook. This lock is to prevent duplicate check #’s from being created.

When this error message appears, the best way to see what is happening is for the user listed in the error to open the program listed. This can be Payroll, Section 8, or Financials. 

1. Open the check process and start a check run for that checkbook. You may receive a message similar to Checks Already Exist – Restart Process? or Checks Already Exist -  Recalculate?  Click NO. 
2. Click the Next button until you see the Print Checks page. Review the Starting Check #.  
   1. Do you believe this is the correct check #?  
   2. If you use preprinted checks, does this number match your next paper check?  If the starting # is less than your next paper check #, then it is possible that a check run was printed but not posted.  
   3. If so, the printed checks will need posted before another check run is started.
3. Click Next to the check Verification page. Are there any checks listed?  If so, what are these payables?  
   1. Do they have check numbers assigned already, or do you believe these payables need checks printed or were these already paid?
   2. If these items have check #s assigned (not all listed as check # zero), then the user printed or attempted to print these checks.  If the assigned check #’s have already been printed, continue as usual with a check run and post these checks.  Once posted, you may start another check run.  
   3. If these items do not have check #’s assigned (all are listed as check # zero), do you believe these payables need checks to be printed, or already have checks printed?  
      1. If these items already have printed checks, you will need to print these to assign check #’s and post.  Click ‘Back’.  Verify the Starting Check # has the correct # for the first of these checks.  Place plain paper in the printer (do not print on real checks), click ‘Print’.   
      2. Verify the new plain paper checks agree with the real checks.  You should match Vendor, Check Amount, Check #.  
      3. If these match, then continue check processing.
4. Click the ‘Next’ button until you see the Print Electronic/ACH or Print Deposit Slips page.   If you are not set up for ACH/Electronic payments, then skip to step 5. 
   1. Click ‘Next’ for the Verification page.  Are there any payments listed?  If so, what are these payables?  
   2. Usually these ACH/Electronic payments need to be posted. 
5. Click the ‘Next’ button until you are on the last step: Post.
   1. Click ‘Finish’ to post.  Even if you found nothing to process, click ‘Finish’.  This will clear the checkbook lock.
6. Users may begin the next Check Processing run.
