ABAP Table Maintenance Events

Hello All ,

I have created the Table Maintenance with Events .

When the user enter the sales order number & item in the Txn code screen of the table .The Event 05 triggers & pulls out information for Sales Order Customer ,Material ,Plant & show it in the screen .

There are two more fields for user input Valid to & Valid from , the user now fills in these fields & then press Save button in the screen .

Now He gets the Short dump related to duplicate entries .

I checked the standard code & it is trying to enter data into the Internal table

MOD_ELEM_TAB & since already the same entry exsist in this table so program dumps out .

Kindly suggest the way to solve this issue .

Best regards,

Anurag Goel .
