Getting Promotion Request items via ODATA / REST api?

Hi all,

i am desperately trying to get the items contained in a promotion request via REST api.

What I have as input is the ID of the promotion request, for example

OR:wt.maturity.PromotionNotice:124606188

It seems one should use

/Windchill/servlet/odata/NavCriteria/NavigationCriterias

, but I am struggling about how to get this with EPMDocPromotionNoticeConfigSpec and WTPartPromotionNoticeConfigSpec and wondering how to get documents / all items contained in a promotion request...

Are there any examples / hints about how to construct the url to get closer to the items comprised in a promotion request?

Best Regards
