What does the field LASTCHANGEDATE in CDS View I_SalesDocumentItem represent?

The customer wants to create a custom report based on CDS View I_SalesDocumentItem and wants to use the field “LastChangeDate” to show the last change date of the sales order item, instead of the last change date of the sales order or the header of the sales order. The customer is wondering if field “LastChangeDate” can realize this requirement.
