RE: cant not delete JE on Initialize Mode
If the batch has an original batch number then it was created by one of the following:
1) from an auto-reversing batch
2) from a recurring batch
3) from the 2011 feature where you can select a batch and click the button to the right of the batch number field and you selected one of the options on that pop-up screen.
the original batch number could be pulled up to see if that was a recurring batch or an auto-reversing batch should you want to know what generated this batch.
Regardless of its origin, you should be able to delete it if it is not posted unless you do not have delete rights to the journal transaction screen. I just ran a test with a user ID who did not have delete rights and the delete button on the toolbar was disabled if the user did not have delete rights but enabled if they did.
I think you need to check your rights to this screen. You could use the SYSADMIN user id and password (if you have those credentials) and try deleting this batch with those credentials. The question becomes if you really want to delete this batch or not. It sort of sounds like you think it was created by mistake and you just want to get rid of it.
Also, look at the batch type. If it is not Nonrecurring, see if you can change it to that, save the batch, pull it back up again and try the delete again.
