Extractors enhancement

Hi to everyone,

i got some troubles when a tried to enhance the structure of the DataSource LIS_12_VCSCL. I cannot use the transaction LBWE cause the field I want in the DataSource structure is not one of those available in LBWE.

If I try to insert the field in an append of the structure MC12VC0SCL and fill the field through an user exit, the DataSource doesn't work, and the field is not filled.

I suppose that if I try to force some field in the structure MC12VC0SCL, the DataSource is not so happy.

Does anyone know is there exists some procedure to enhance a DataSource without passing through LBWE?

Tenx so machhhhhh
