Trigger a Update on OIM field to OID

Recently we had a requirement like we need to update a field in OIM and it should inturn update in OID.Many of you might know how to achieve this.This is only for some basic understanding.

Steps

1.Create a user defined Field say UserDN(USR_UDF_USERSN)

2.In OID process definition create a task like Change UserDN and map it to modifyuser adaptor.While doing the attribute mappings for Attrvalue map it to user Definition(UserDN) and AttrName make it to literal(UserDN)

3.Go to Lookup,Search for *USR_Trigger*---For code key(USR_UDF_USERDN)and in decode key(Change UserDN).the decode should be same as that of task name in process definition(I Presume this)

4.Go to OID attribute mapping(AttrName.OID.Map) . In code key add the OIM fieldname and in decode key map it to OID attribute.If the attribute is created in process form add the code key to Process form field name and decode key to OID.

So whenever a user is getting updated in OIM,It will change the value in OID.Also note that to update that field in OIM proocess form create process definition tasks like UserDN Updated.Also add a prepopulate to the field to update in OID form.
