You must explicitly include a stored procedure name in the classification criteria if you want it to be covered by a system throttle. Otherwise, TASM ignores the stored procedure CALL statements and throttles only the SQL within the stored procedure.
TASM counts each time code calls a stored procedure. However, if a stored procedure calls itself, TASM does not count that. Consider the following example:
CALL ABC ABC calls DEF DEF calls DEF (recursive)
A throttle of 1 on stored procedure DEF will not impact this example.
