How to publish a fourth-order form in document control?

Level 3 and level 4 documents are related to which department, and will only be sent to that department when used. However, if the original document is kept for document control, there are two methods: 1. You can consider not numbering them first, and then publishing/printing them under control after a one-week trial period. 2. If you change the form, directly replace the original form without changing the form number. Be sure to recycle all the invalid materials and avoid using them, but you can't say that to the outside world, except that the form has not changed. )
