Effective in version 10.0.0 HotFix 3, all processes that calculate the best version of the truth treat null values the same way. Previously, some processes ignored the
Allow Null Update
property in the staging table and used the
Apply Null Values
property in the base object table.
When a source system contributes a null value for a column, a process refers to the setting of the
Allow Null Update
property for that column in the staging table.
If the
Allow Null Update
property is enabled on the column, the process can write the null value to the base object record.
If the
Allow Null Update
property is disabled on the column, the process downgrades the trust for the null value.
If a process cannot resolve the setting of the
Allow Null Update
property in a staging table, the process uses the setting for the
Apply Null Values
property in the base object table.

Allow Null Update
property, see the
