When attempting to edit and save save an Interactive Report (IR) or Interactive Grid (IG) after changing a row with a varchar2 column with data close to 4000 bytes (like 3990 or higher)
the following error occurs.
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
The issue can be reproduced at will with the following steps:
1 Create an IG or IR based on a table with a varchar2 column where data has been entered close to the 4000 limit -- this column is read only in the report
2 Display the report and try to change other columns (any simple one character column per example) -- notice that you have not added more data to the varchar2 almost full
3. Try to save the Row, get the error
WHAT IT WORKING
Other rows in the same IG are able to edit and change values and save IF the varchar2 column has less characters on it (like 3800 per example)
Created a new report page based on a table this table with varchar2 column where some rows fill in the capacity of the column
