I have an Augmented attribute created and in there I update the execution date of a specific action flow. My question is, does this value "Execution date augmented attribute" kept in the Knowledge model despite data loads ?

Thanks for your posting. I understand that you are asking about the Augmented attribute in the Knowledge model. As the following URL described, the data of the Augmented attribute is independent of Data Model loading. https://docs.celonis.com/en/knowledge-model---augmented-attributes.html#idm45792470492144:~:text=What%20Augmented%20Attributes,Views%20here. Thanks for your understanding.
