ORA-12899: value too large for column error

Hi All,

I have a job with pulling data from flat file and load into Oracle(staging) and finally load data into BW(Target). As a daily schedule monitoring I found a issue regarding "ORA-12899: value too large for column" error. I went through flat file and verified all records having 25 char length, and source having 684 records and this 684 records loaded by looking monitor log and job failed with above error. If all records having 25 char length, why I am still getting "ORA-12899: value too large for column" error.

Here is monitor log

Note: I am getting 0 records form source(F_HEALTH_ELEMENTS 1) file where I marked green

Here is error log

"STAGING". "HEALTH_ELEMENTS_TEMP_LOAD". "LONGDISCRIPTION" (actually: 26, maximum: 25)

Please help to understand the actual issue
