Question

Hi:
    I created a LIS 'S902' ,it was copied from S066. and use TCODE 'MCSCHECK' check is OK.  there some different in the update programs as follow:
    When  a Customer Credit Management is not maintained, the RETURNCODE value '4'. mean don't need to update new recode into this table and call FM 'stat_curr_convert_ex' to convert curr. if call FM 'stat_curr_convert_ex' to convert curr, have some error :"Error determining local currency: ER type
2008.05.20 from CNY to  RC 4".
    How can i use RECURNCODE to deal with the error?
    or how can i control the program of RMCX0002  was not executed when When   Customer Credit Management is not maintained.
