This function is a filter that can be applied if under Admin > Spend Settings > Spend Settings > Categorization method you have chosen 'Vendor - category' or 'Cost type - category link'. You can make exceptions for one of those connection types using 'Vendor - Cost type - Category link'.
You can set that invoices from a vendor with a certain cost type are linked to a different category than the standard setting in Admin > Spend settings > Data aggregation> Connect categories.
Changes to this overview must always be confirmed via the 'Process' button in Admin > Spend settings > Data aggregation> Connect categories. The changes will then be processed the next night and are usually visible in your ISPnext environment the next working day.
Example:
Example settings in Admin > Spend settings > Data aggregation> Connect categories:
Cost type 'Software licenses' is linked to the category 'Software' by default. All invoices from all vendors with the cost category 'Software licenses' are linked to the category 'Software'.
It is possible that there are vendors whose invoices with the cost type 'Software licenses' must fall under a different category.
You set the following link in Admin > Spend settings > Data aggregation > Connect vendor/cost type/category:
Cost category: Software licenses
Vendor: ABC Software
Category: Software process management
All invoices with the cost type 'Software licenses' are still linked to the category 'Software', except the invoices with the cost type 'Software licenses' from the vendor 'ABC Software'.
