Praneeth,
I'm not sure what configuration your screen shot is showing. If this is the overall release indicator for the document type, then it will have a large effect.
For each document type you can decide on overall release (release the entire requisition as a whole) or item-based release (release each item separately). Then in the configuration for requisition release, you have to overall release vs. item-based release for each release group, and assign a class to the group.
If you want to have item-based release for some document types and overall release for others, you can do so. But all the item-based release groups must use the same class, and all the overall release groups must use the same class.
