Question Creating a mapping to write into a sheet

Hi,

I am trying to insert data in an Excel sheet.
I have a really simple Mapping with two objects:
- In source : a SQL Server table
- In target : an Excel sheet (from an excel file I reversed)

I followed the "Getting started with Stambia's JDBC Excel Driver", and did everything mentioned in the tutorial, but when I execute the mapping, I get an error during the Integration part (Load of data) :
com.indy.engine.common.exceptions.EngineExceptionI: Exception for source column 1 and target column 1
at com.indy.engine.actionCodes.JdbcActionCodeI.a(SourceFile:598)

... 7 more

The "Load of data" generated code is :
insert into "ErrorFichierRetourMAJadmin"."Feuil1$"
(
"file_name",
"date_creation",
"type_enregistrement",
"ref_externe",
"num_ordre_dem",
"donnees"
)
values
(
:{L1_file_name}:,
:{L2_date_creation}:,
:{L3_type_enregistrement}:,
:{L4_ref_externe}:,
:{L5_num_ordre_dem}:,
:{L6_donnees}:

)

I could not find a way to resolve it, do you have any idea?

Thx

Hi,

I did disable the columns one by one but it still doesn't work..
Same error, same message "com.indy.engine.common.exceptions.EngineExceptionI: Exception for source column 1 and target column 1"
I'm mapping Nvarchar type from source to Varchar type on the target, so I don't understand what I'm doing wrong
