To some degree, therapy approaches have some overlapping principles and depending on the needs of the client for that session a therapist may integrate an approach where questioning style changes to gather further information, get the client to open up further, view situations from a different prospective, which will hopefully gain better results. The main approach can still be SFT, which you will bring the clients focus back to that approach.  

then l wrote this to add to my  answer 2nd attempt

When SFT is combined with other therapies its best when using a strengths-based approach. Eg. SFT and Narrative therapy approaches see the client as the expert in their own lives and using mindfulness, motivational interviewing and problem-solving approaches 

They then responded with this:

Please provide specific examples of how techniques from SFT and narrative therapy may complement each other approach.

This was my anwer just above but BUT they wanted a specific EXAMPLE here of how SFT could be combined with another approach .

Could you please help me giving a specific EXAMPLE of the  combined SFT and Narrative into a technique to be used in a counselling session.

thank you
