Error Code: IFC12045 (can't identify exact schedule)

The below error message means that Nest can't recognise which contribution schedule you are trying to make a submission for based on the data sent from payroll.

IFC12045 - We are unable to identify the exact contribution schedule. Please log in to your account and select the schedule you want to pay.

This normally happens when there are two or more Groups on the Nest scheme with very similar settings. 

Nest identifies contribution schedules using the following data items in their contribution file header:

• Period end date
• Payment Due Date
• Payment Source (SubGroup)

This specific error message only occurs when there is confusion over the Payment Due Date because of the way two or more Groups have been configured in Nest. 

The Payment Due Date is configured as part of the Group set up, and Nest offer two ways of configuring it:

• Relative Date - e.g. 10 days after the end of the pay period
• Specific Date - e.g. the 10th of the following month

When Nest creates a contribution schedule, it looks at the Period end date, the Payment Due Date and the Payment Source (the items that appear in the header row) but it also takes into account whether the Payment Due Date is on a Relative or Specific Date basis (but this info can NOT included in the header row). 

If a Nest scheme has two Groups, for example, where:

• The Period end date on both is 31st December
• The Payment Due Date on both is 10th January

BUT

• Group 1 was set up using a Relative Date
• Group 2 was set up using a Specific Date

This would result in there being TWO virtually identical contribution schedules in Nest. It would be impossible based on the Period end date, Payment Due Date and Payment Source in the file to determine one contribution schedule from the other. So Nest rejects the file with the IFC12045 error message. 

Removing this issue

To remove this issue, you need to review the Groups that are set up on the scheme in Nest. You can add, copy and delete Groups in the Manage Groups section of Nest as required, and you can move workers between Groups in the Manage Workers section. 

If you have workers in two or more Groups with the same Period end date, Payment Due Date, Payment Source and the Payment Due Date is configured on the same basis, this should result in only ONE contribution schedule being created in Nest.
