# [Yandex DataLens] Reading multiple dynamic tables or dynamic table together with static table is not supported in CHYT

`ERR.DS_API.DB.CHYT.MULTI_DYN_NOT_SUPPORTED`

This error occurs when one CHYT query reads several dynamic tables or reads both a dynamic and static table at the same time.

To fix it, leave only one dynamic table in the query, split the query, or first materialize relevant data into a single static table.
