Hello Dnyanesh,
The error is normally caused because that the hierarchies and categories have already been replicated from an R/3 system that is different than in table COMM_HIERARCHY (see LOGSYS). As a consequence of this there is now a mismatch between the environments.
In order to resolve this error, please run the program COM_HIERARCHY_DELETE_ALL which will delete all the existing hierarchies and categories in the CRM system. Then repeat the initial load of object DNL_CUST_PROD1. Please note that it is NOT recommended to process this report on your production system.
Please see KBA 1943617 for more information.
Best regards,
Julin Xin
