When i have to distribute the new sop to concerned department

In revised SOP, to day is sop approved date, when i have to give effective date, shall i write post date on today or after getting trainings, if post date how to ensure before effective date i will get trainings. sorry for bad english.

after completion of training for all who required that sop,you have to give effective date for the revised sop.

Give the training after approval of sop , if any correction required in sop correct it and mention the effective date and distribute the sop.
