SAC Datasources Missing After system refresh from production

[#1]

Hello Colleagues,

We have refreshed SAP BW sandbox system (CLA) with SAP BW production system (CPA) using HANA DB restore method.

As part of Source system connectivity restore from production to sandbox, we have performed below steps.

1) In HANA Data Provisioning, created a new Remote Source SACCLA pointing to SAC QA system

2) Granted Remote Source subscription and table creation option to user SAPCPA as per NOTE 2356824.

3) Edited connection details of SACCPAPRD to point to the new Remote Source in Point 1. Choose option Activate extractors during the execution.

After that below SAC Datasources were missing from sandbox system (CLA)

1. ZDS_PNF_COMM_RET_DLT
2. ZDS_PNF_FACT_RET_DLT

Just wanted to understand is this because of SAC source system re-creation and activation or?

Thanks

Pradeep
