Folio issues with Data consistency

This page contains examples of issues with Data consistency in Folio. The issues could fall into one of the following categories:

• There is no logic to make sure a data is consistent across a set of modules

• There is a logic to perform data consistency, but it isn't reliable and can lead to inconsistent data in a set of modules

Data redundancy in models

1. Pair of RefNumber and RefType should be in consistence state between POL and invoice line.
2. FundCode should be in consistence state between Fund record and pol.fundDistribution.code.
3. VendorCode should be in consistence state between Organization record and purchaseOrder.vendorCode.
