SAPSQL_ARRAY_INSERT_DUPREC" "CX_SY_OPEN_SQL_DB in VA02

Hi Experts,

              I have an issue when tried to update the reason for rejection for a particular line item.

When updated the reason for rejection..and press save  ,system prompts to select the schedule line, when it is selected...program says update terminated..

   With error as

"SAPSQL_ARRAY_INSERT_DUPREC" CX_SY_OPEN_SQL_DB

"SAPLV45U" or "LV45UF0V"

"VBEP_BEARBEITEN"

Report-LV45UF0V

Row 257

Source code...

INSERT VBEP FROM TABLE DA_XVBEPI.

while debugging, it is not prompting to that Insert statement.
