Variables getting deleted when Rich Client Report is published

Dear All,

I am using BO4.1 SP3 with Bex as data source.

I am facing below issue:

Whenever we are developing Report in Rich client and exporting to the repository

On opening the Report in BI launch pad, all the defined variables will be deleted automatically.

Can someone please guide what can be the issue?

Thanks.

Warm Regards,

Sonal
