Specify normal OIs or specify special G/L transactions

What causes this issue?

You neither marked that you want to select normal open items (item
without special G/L indicators) nor have you specified special G/L
indicators to which open items should be selected specified.
Consequently, no open items can be selected.

System Response

You are asked to specify the type of open item.

How to fix this error?

Mark the "normal open items" or enter the desired special G/L
indicators. A combination of both entries is possible.
