ETag should not be checked on PATCH Operations
In the PATCH operations, it should be avoided the check of the ETag, since the operation will be asynchronous. In fact, a 202 Accepted is returned and as reported in the spec (Table 5.4.3.3.4-2 of SOL003):
The request was accepted for processing, but the processing has not been completed.
