Hi Sunita;
I do not have any specific knowledge if this software would work with PB - however, the IBM product does support a COM callable API, which PB Does support. So I would imagine that this connectivity option should work. Hopefully, someone will "chime in" here to confirm!

The other alternative would be to use the .NET interface that the IBM Client also supports. You would not be able to use this until PB 2019 R2 is officially released, but one of the great new features of that PB release is the ability to directly consume (call) and .Net Assembly directly from PB.

PB2019 R2 => .NET Assembly => https://docs.appeon.com/appeon_online_help/pb2019r2/whats_new/ch01s03.html
