How to find and run the Landmark Validation URLs

Problem:

I ran AP155 and AP170 before running AP150 and received the same message that there is no data in report file.  I ran AP150 again and am seeing the same message.

Please see screenshots below:

Resolution:

Check AP52 if it shows that these invoices are waiting to be brought into Lawson via AP520.

Run the AP520 in update mode and then process the AP150.
