Hi nsun - Welcome to the Dynamics Finance community! Thanks for your question. I checked in with some of the friendly folks on the Dynamics SL dev team and they gave the following two suggestions.
1. In General Ledger: Journal Transactions – Select Journal, Highlight detail in grid, Copy, then paste in Excel.
2. Run the report GL Transactions use the ROI to select records. Press the Printer Option button on the bottom right of the ROI screen.
In the Printer Options select Print to File, then select the Setup… button on the right.
On the left side of the screen there is a drop down box: List Types of Files. Select appropriate Excel.
Enter appropriate File name and File location to create Excel document. Then press OK button.
Press OK button on Printer Options.
Then press Print button on the ROI screen.
Hope this helps
Craig
