        Is an instance of type E_KnowledgeItem.A_Loc.

§      In: Locator_B

–      RC_ok

–      RC_syserror

–      RC_seeAppErrors


Has to:

Ensure the existence of a relationship X satisfying

–      X.a_A = Locator_A

–      X.a_B = Locator_B

–      X.a_Correlation = CorrelationType

Please note:  If exactly this relationship already exists, the function is to return RC_ok.



Because of:

C_WissDB_API needs a way to create associations of type R_Is_related_to.
