Hi there,
I'm having an issue where we're importing new custom ProductFields via the data integration and using a custom provider as source and the Dynamicweb Provider as destination.
The productFields are correctly imported (they are visible in the EcomProductField and in the environment under 'Global custom fields'.
The product design or configuration has not been updated after the integration job, so there is a difference between the amount of productfields and columns on the EcomProducts table.
Trying to open a group in the PIM results in an undefined error
Saving a newly made custom field does create the column in the EcomProducts. Is there a way to make this automated?
For example: 
'ProductState' is added a custom field, which is not there in the EcomProducts design
Also found this issue using the excel provider as source and importing 1 test productField.

Kind regards!
