I am trying to figure out how can I allow users who don’t have “Submit” rights in a doctype, to update fields marked as “Allow on Submit”, because currently they’re not able to save the document after submission.
Is there any way I can allow them to edit those fields without giving them submit rights?
Yes, it may be possible - you need to work upon field level permissions feature in ERPNext.
Refer to ’ Permission Levels’ section in the ERPNext official documentation.
I am ignoring permissions on those fields, so i guess there is no issue of permissions on those fields, as check they can edit those fields and but can’t save/update the document because it is submitted and they don’t have submit rights?
