# Limitations and considerations

When using SAP ODP as a source endpoint in a Replicate task, the following limitations apply:

* The "Start from timestamp" and "Start from position" options for running tasks are not supported.

* The [Allow unlimited LOB size" and "Optimize handling when LOB size is less than](https://help.qlik.com/en-US/replicate/November2025/Content/Global_Common/Content/SharedEMReplicate/Customize%20Tasks/target_metadata.htm) LOB handling options are not supported.

* Source lookup is not supported.

* SAP ODP endpoint uses the metadata of the ODP node. Consequently, the target tables will be created with these ODP-provided columns.

* Hierarchy objects and columns are not supported

* Metadata changes are not supported. In order to make changes to the metadata of the ODP node, the task must be reloaded.

* When using the SAP ODP endpoint in a Log Stream configuration, Full Load replication is not supported.
