Finally after all the research I got the answer for my question.

We have to use INode to get the part sub class node then get it child nodes. One of child node is LifeCycle Phases, for this node you can get the child nodes which are our lifecylce associated with the part sub class.

Steps to achieve it:
1. Get part sub classs using IAgileClass
2. Get level 1 node for part sub class
3. Get all childs for level1 node in Collection object
4. Iterate through it to look for LCP
5. Get Child Nodes of  LCP in another Colleciton object and here you go

I am fairly new to Agile PLM SDK developement but I think for all configuration related data we need to refer using INode which is also stored in nodetable in database.

Am I to understand that there is are specific lifecycles phases depending on the subclass?  Please provide examples.

Yes the design was made to have additional lifecycles other than OTB Preliminary, Prototype and Production released. We have lifecycle phases like concept and others which are specific to part subclasses.

So they are not specific to part type…. need to go into the PART class and look under lifecycle phases there… you can add and deactivate options there.

 Lifecycle values are always in the NODETABLE table. To check if an LCP value is linked to a specific subclass, you would need to follow the hierarchy in NODETABLE. Each class has a defined node underneath it for “LifeCycle Phases” (select id, description from nodetable where parentid=10000), it is 1514 for Items, 9043 for Documents and 9045 for Parts. Each class also has a node for “User-Defined Subclasses” (10141 is the ID for the Part subclass). If you look in NODETABLE using that value as the PARENTID, you will see a node defined as “LifeCycle Phases” for the subclass. This is the parent ID for the LCP values defined specifically for that subclass.

 If you are using SQL, just get the ID for the subclass, find the ID for the “LifeCycle Phases” node, and then check to see if it has a record with the lifecycle value you want to use under it. If you are using the SDK, it should work something like this :

private static void checkLifecyclePhase(IItem item, String lcp) throws APIException {
// Get the Lifecycle Phase cell
   ICell cell = item.getCell(ItemConstants.ATT_TITLE_BLOCK_LIFECYCLE_PHASE);

// Get available list values for Lifecycle Phase
   IAgileList values = cell.getAvailableValues();

// Run through the LCP list to verify we are using a good one
   int cval := -1;
   for (int i = 0; i < values.length; i++) {
      if ( values[i] = lcp ) {
         cval = i;
      }
   }

   if (cval >= 0) {
// Set the attribute to the value we got as an argument which was found in the LCP list
      values.setSelection(new Object[] { cval });
      cell.setValue(values);
   } else {
      throw new Exception(“Could not find ” + lcp + ” in the life cycle values”);
   }

}

 My apologies if my Java isn’t correct, I am a bit rusty…..  But the above should give the general idea of what to do. When you get the list of lifecycle values, it will include the base Item LCP values, the class LCP values  *and* the subclass LCP values. So every valid LCP value for the item in question will be in the array. You find which one matches the value given as the argument, and then set it. If it is not found, then throw an exception or handle as needed.
