Hi Sri,
the document you are seeing is the initial record of the incident: a near miss. The system documents the initial reporting state as a document. If further changes to the incident record e.g. a category change occur, these are stored audit proof within the change documents.
... in case you need another initial record, you could trigger an action by implementing BAdI BADI_EHHSS_INC_CHANGE_CATEGORY.
Kind regards
Joachim
