values 
(MODS_SEQ.NEXTVAL,3434,2843,2453,2392,435,2390,'pension.txt','rereee',454545,3434);

    First, do a describe on LGN_INDEX on that table to make absolutely certain you are looking at the right column. Is LGN_INDEX a constraint+index or just an index? Try re-building your index to make sure it isn’t corrupt. Make sure you don’t have any other constraints that might be interfering.

    Second, perform a SELECT MAX(LOGINID) FROM TEMPLATEMODULE and compare that to the next sequence value to make sure your sequence isn’t set lower than the maximum ID you are working with.

    Third, check if you have any triggers on that table.

    If none of these things work, try re-creating the table using just the schema. Cross-load the data and try again. There might be a configuration setting on that table that is causing the issue. CREATE TABLE MY_TEMP AS SELECT * FROM TEMPLATEMODULE.
