What is running when an APPL's version isn't found?

A menu hase Base_Appl_A|Our_Vers_1 which has a row exit to Base_Appl_B|SL_Version_name.
Base_Appl_B launches Our_Vers_1.

Base Appl_B has a row exit to Base_Appl_C|SL_Version_name
however Base_Appl_C|Our_Vers_1 does not exist.

Base_Appl_C runs and SL_Version_name states "Our_Vers_1".
Is this running ANY version, or just the template?
