An ABAP subroutine has been called recursively too many times. This is
probably due to a conversion exit or a user exit triggering the same
exit again and again. These exits are implemented by function modules
with the names CONVERSION_EXIT_xxxxx_INPUT/OUTPUT or
USER_EXIT_xxxxx_INPUT.
You can find out which ABAP routine is affected by consulting "Active
Calls/Events". Conversion exits are triggered during screen field
transports or WRITE statements. Field exits are triggered during field
transports from the screen to the ABAP program, meaning that they are
not called directly by an ABAP program. The most likely scenario here
is the implementation of a conversion exit containing a WRITE statement
for a field that the same conversion exit is assigned to in its
Dictionary domain. As a result, the exit is triggered recursively.
A maximum of <runtime parameter> of these ABAP subroutine calls can be made.
