Hello there,

I have an issue with my trigger, here is the error message that i get :  : System.DmlException: Update failed. First exception on row 0 with id a1G0E000001T6wgUAC; first error: SELF_REFERENCE_FROM_TRIGGER, Object (id = a1G0E000001T6wg) is currently in trigger OC_EquipementUpdateWithReferentiel, therefore it cannot recursively update itself: [] Class.OC_EquipementTRIGGER.updateParent: line 181, column 1 Trigger.OC_EquipementUpdateWithReferentiel: line 23, column 1: []: Class.OC_EquipementTRIGGER.UpdateEquipWithReferentiel: line 73, column 1

There is a particularity in here : parent and child are on same object, but with different record type. 
When i create a child record and a parent is find, i need to update parent status to say it is used by someone. (in method update parent) that create this meessage error when i try to update a parent equipment. 
Anyone can help with that? 

Ty in advance :)
