In the Replicate User Guide, it states: when using Log-Based CDC method, delete and updated operations are not supported for filtered records for SAP HANA source endpoint.
Ref: https://help.qlik.com/en-US/replicate/May2021/Content/Replicate/Main/SAP%20Hana%20Source/limitations...
When Replicate reads a DELETE operation for SAP HANA source, it only gets the values of the columns of the PK and not any values of other columns.
Thus, the limitation on DELETE is only for columns that are not part of the primary key.
