Creating object link for Maintenance Order Operation to attach images to it?

[roshan89]

In case we need to add image(s) to the operations of the maintenance work orders. I have created a new doc type IMG for it in DMS config. Now as I need to link this doc type to object, in that step I do not see any object that is related to the Order Operations? My doubt is if we have to create that first, then how can we do it OR am I approaching this in a wrong way?

Adding additional context to the question: This is being set up in SAP because we are expecting the end user to add images in the operations using SAP Service and Asset Manager app.

Any help on this is much appreciated..! Thanks.
