Some source data has not been used

Hello,

 

 

I want to aggregate shapes from several subdirectories that have the same path and name structure. So "SourceDadtaset_SHAPE" =

 

N: \\ service \\ group \\ thematic \\ ** \\ shape \\ unites _ * _ 2.shp.

 

The script reads all shapes correctly, says the transaction was successful but displays "Some source data has not been used. This can happen if the dataset is changed or if a feature type is renamed or Deleted. "

 

 

However, it is not the case

 

 

Do you have an idea ?

 

 

Thank you
