Hi rui,
As my guess there is no sid value for one the value of 0fiscper.
you can sid table of your 0fiscper. there will be a blank for one record.
Have you done RSRV test on sid inconsistency. please check on it.
if there is no sid value then by using function module you can generate it.
FM - RRSI_VAL_SID_SINGLE_CONVERT.
Thanks
