Good morning,

I use Snap 7.0 and this is my graph:

When I try to run it, I have the following error:

The Product 'Subset_projected_S3A_SL_1_RBT____20190826T140456_20190826T140756_20190827T175944_0179_048_281_3060_LN2_O_NT_003.SEN3_500m_resampled' already contains a band with the name 'F1_exception_in'

Can anyone help, please?

Best regards,
Livio

Hi Livio,

this is an issue in the AddLandCover Operator in version 7.x.
If you update to SNAP 8 it should work.

Thanks so much Marpet for your suggestion
