In GL distributions, users often want to copy a distribution reference to all of the lines. Well, there is no magic technique to make that happen but there is away to make it easier.
Start by expanding the GL lines to show the Distribution Reference
Enter the reference in the first line
Copy the first line’s reference
Press the down arrow to move to the distribution field on the next line
Paste the reference
Press the down arrow again and repeat until the reference has been copied to all of the lines.
