Hi,
Yes you can use any external table and show into AwareIM Grid but there are some restrictions related to standard features of grid like filter and sort.
Paging will work.
If you using external table there is no requirement to have BASTIMESTAMP or BASVERSION col. If you create table using BO inside config and create your data using SP with respecting the BAS ID and version and Timestamp, this will allow you to use complete grid features.
