There is no way to have customized reporting in Acelynk. The fields in the entries should all be searchable via reporting and you should be able to add or remove columns that you need in order to run some customized reporting. For example an importer requests their duty amounts for past shipments, but when you provide the report, there is no way to match up the entry to their PO#. The PO# we place in the entry is in the Importer Ref field on the entry, but there is no option to have that on the reports.
Enhanced Ad Hoc reporting is planned as a future product. We will share more with the community when it is available.
