Marty/Mathias,
We have similar issue since November. I have an open Incident with them since November 18th. Incident Number is 961362. We even told them what they need to fix as described below. Still Waiting.
When a dependent changes types in the middle of a month (i.e. domestic
partner changes to spouse, court ordered dependent changes to child) it
is creating two records for the same dependent. Although the table
HRBENUS_D_ADDATA also has keys for the subty and objps, SAP is not
populating them and the program is failing.
Class: CL_HRBENUS_ACA_ENGINE
SAP Method: FILL_ADDATA_COVIND
