Administrative detention generally does not affect the promotion of cadres. However, the staff of state organs are not allowed to have criminal records, and administrative detention belongs to administrative punishment, not criminal punishment, so it is OK from the point of view of margin. But look at the unit. Some units need to have no record of violations of laws and disciplines, so it is not possible. According to relevant laws and regulations, if an illegal act constitutes a crime and the people's court sentences the party to criminal detention or fixed-term imprisonment, if the administrative organ has already given the party administrative detention, the corresponding term of imprisonment shall be converted according to law.
 If an illegal act constitutes a crime and the people's court imposes a fine, the administrative organ shall offset the fine if it has already imposed a fine on the party concerned; If the administrative organ has not yet imposed a fine on the party concerned, no further fine shall be imposed.
