Internet Explorer 11 desktop app retirement

Microsoft has announced that Internet Explorer will no longer be supported from 15 June 2022.
Organisations using SAP Interactive Forms by Adobe for interactive forms for data collection will need to replace that technology.
In note 2692483 SAP recommends users of SAP Interactive Forms by Adobe to redesign their applications, since Internet Explorer 11 will not be supported by SAP.
For Varo customers using PDF, the upgrade path is to migrate to HTML forms with Varo, or to Fiori apps with Stelo. But this project will require time and effort, so it is critical to begin planning the migration immediately.
Customers not using Varo need to decide whether to implement an e-forms solution or use Fiori.
In all cases, our recommendation is to use Stelo to replace any custom interactive PDF processes.
