I am clearing a vendor document via F-44 with Charge Off Difference.
1. Selected Document Number 1001 at $1000
2. Clicked on Charge Off Difference and entered Posting Key 50 to GL A
3. Simulate posting
4. System will have the Line Item 2 created for Posting Key 40 of the same amount $1000
At #4, the field Reference Key 1 is grayed out. How can make this field input-able?
