Hello Daniela Drook,
1. Check the excel importer module is compatible with 10.18.6 if not select the correct version.
2. Try to create new template from scratch, it may be possible existing one is corrupted.
3. Check the MF IVK_Column_Save ,check parent object is committed before saving child objects.
4. Add log in IVK_Column_Save and verify parent object are proper.
Hi,
In IVK_Ciolumn_Save microflow make sure to commit the Column object and refresh the commit action.
