1. A method of processing video data, comprising:
determining, for a conversion between a video unit of a video and a bitstream of the video, a first syntax element and a second syntax element; and
performing the conversion based on the determining,
wherein the first syntax element and the second syntax element have an equivalent functionality,
wherein the first syntax element is included at a first level in the video unit in the bitstream, and the second syntax element is included at a second level in the video unit different from the first level,
wherein the first level is a picture header and the second level is a slice header, a sequence parameter set or a picture parameter set, or wherein the first level is a slice header and the second level is a sequence parameter set or a picture parameter set,
wherein the first syntax element specifying whether a use of an explicit scaling list is enabled is included in the slice header, and the second syntax element specifying whether the use of the explicit scaling list is enabled is included in the sequence parameter set, and
wherein the first syntax element is not included in the slice header when the second syntax element is not included in the sequence parameter set.
