Open the 
Item Journal window and click
Functions, Get Standard Journals.
Note: This topic refers to the item journal, but the information also applies to the general journal.
When you need to fill an item journal with lines that you have saved as a standard journal, you use a function to copy the standard journal lines into the item journal.
Open the Item Journal window and click
Functions, Get Standard Journals.
The Standard Item Journals window appears showing codes and description for all existing standard item journals.
To review a standard item journal before you select it for reuse, click Standard, Show Journal (or Shift+F5).
Any changes you make in a standard item journal are implemented right away – that is they will also be there next time you open or reuse the standard item journal in question. You should therefore be sure that the change is important enough to apply generally. Otherwise, make the specific change in the item journal after the standard item journal lines have been inserted. See step 5 below.
Back in the Standard Item Journals window, select the standard item journal you want to reuse and click OK to complete the Get Standard Journals function.
Now the item journal is filled with the lines you saved as the standard item journal. If journal lines already existed in the item journal, the inserted lines would be placed under the existing journal lines.
Normally, that is, if you did not check the Save Unit Amount field during the Save as Standard Journal function, the Unit Amount field on lines that you have inserted is automatically filled with the item’s current value (copied from the Unit Cost field on the item card).
Note: If you checked the Save Unit Amount and/or Save Quantity fields, you should now make sure the inserted values are correct for this particular inventory adjustment before you post the item journal.
If inserted item journal lines carry saved unit amounts, which you do not want to post, you can quickly adjust it to the current value of the item:
Select the item journal line(s) in question and click Line, Recalculate Unit Amount. This will update the Unit Amount field with the current unit cost of the item.
Post the item journal.
