What will you do when you find that an existing add$-$on from an Independent Software Vendor $($ISV$)$ is not supported in SAP S$/4$ HANA?

$1$ point

After you implement SAP S$/4$ HANA, the customer can choose to do custom coding to make the add$-$on compatible with SAP S$/4$ HANA.

Propose a solution to get a compatible version of the add$-$on or information to uninstall the add$-$on from the vendor.

You can ignore the add$-$on$.$ It will not be a showstopper in the implementation.

Discuss with the customer and remove the functionality from the business requirements documentation.
