Here is a sample for recursive search for forward and backward.

////////////////////////////////////////////////////////////////////

///     - [String] itemtype: itemtype's name of RELATIONSHIP
///     - [String] is_all_level: return all levels or only the top/end
///       - 0(default): top/end only
///       - 1: all levels (all children or all parents)
///   - OUT:
///   - RequestState
///     - [String] returnIDs: target IDs (csv)

I've tried this and it doesn't repeat since you put the fix id to the related_id's Item. It always do one level I think.

Hi Maddy, As I understood your query, your are trying to do reverse operation using GetItemRepeateconfig. You can try below AML then, <AML> <Item type="Part BOM" action="get" repeatProp="source_id" repeatTimes="2" select="source_id(name)" > <related_id> <Item type="Part" action="GetItemRepeatConfig" select="name" id="{your bom part id}"></Item> </related_id> </Item> </AML>

Actually I write AML query for getting all parent item. In my bom tree I want parent Items (with all properties). i.e I run AML query on item which is at 2nd level in bom, so I want Its parent and Parent's parent (with all) property. Is there any reverse method to do this?

Look at the very nice Erik Domke's documentation (hoping it will or maybe it has been migrated to github already) amlstudio.codeplex.com/wikipage
