This section deals with the handling of add-ons by ZDO.

• All installed add-ons in the system must be ZDO compliant to perform an update with the ZDO functionality. See SAP Note 2707731 for a list of add-ons that are not enabled for ZDO.

• If you have add-ons in the system that are not enabled for ZDO, you can request a customer-specific project. For more information, see section 6. Registration Process for Customer-Specific Projects of SAP Note 2707731 .
