DELTA for Custom Field Enhancements

Hi,

I have enhanced an extractor (0MAT_PLANT_ATTR) and added a field PRMOD from other table and is not found from MARC. The said field is populated via a User Exit during extraction through a SELECT statement.

However, when I change the value of the Forecast Model, it does not produce a DELTA Update.

Kindly help me with this one.

Thanks!
