Strange error: COMPUTE_BCD_OVERFLOW

Question

Hi everyone,
i have a very very strange error/exception trying to divide 2 Numbers:
The source code looks like this:
lv_alt_koeff = ABS( lv_alt_wrbtr_delta / ( lv_alt_wrbtr_h - lv_alt_wrbtr_s ) ).
Values are:
lv_alt_wrbtr_delta = 119201.40
lv_alt_wrbtr_h = 0.00
lv_alt_wrbtr_s = 4124.05
Can you please explain me what i'm doing wrong and how to get off this error.
Thank you very much in advance.

Answer 1

Check the data declaration of the variable which holds this value. If the resultant value  is too large then the ABAP throws this exception.
You may handle this using CATCH ENDCATCH statement.
Check this e.g.:
PARAMETERS fact TYPE i.
DATA: fact_save TYPE i,
      res(16)  TYPE p.
ARITHMETIC_ERRORS contains COMPUTE_BCD_OVERFLOW ***
CATCH SYSTEM-EXCEPTIONS ARITHMETIC_ERRORS = 5.
  res = fact_save = fact.
  SUBTRACT 1 FROM fact.
  DO fact TIMES.
    MULTIPLY res BY fact. "<- COMPUTE_BCD_OVERFLOW
    SUBTRACT 1 FROM fact.
  ENDDO.
ENDCATCH.
IF sy-subrc = 5.
  WRITE: / 'Overflow! Factorial of', fact_save,
                               'can not be calculated.'.
ELSE.
  WRITE: / 'Factorial of', fact_save, 'gives', res.
ENDIF.
