When closing the G/L during the Journal Header section one of 2 error messages are received. One is a Btreve Error 2 and the other is Btreve Error 19. If I keep clicking the OK eventually the G/L close finishes.
Since these errors are occurring during the month end close, I would restore a backup prior to starting the close. In addition, if you also receiving a Btrieve status 2 error - that generally means damage to your data and you will need to restore a backup. If the Status 2 error has been occurring for awhile, you may need to restore an earlier backup. If you have any concerns with your data, I would recommend working with a support analyst.
Here are a few articles relating to the errors you mentioned:
*Error: "Btrieve Status 2. The Application encountered an I/O error" (20290)
*Error: "Btrieve status 19, dfg dbierr -syscurrup. Your system is corrupt" (34909)
*Month-end close or data rebuild does not finish successfully (18696)
*How to restore a backup (73033)
The errors you are receiving are too complex to troubleshoot in this forum and I recommend calling support to work directly with a support analyst 800-447-5700.
