Dear Darshand
"OWNID"s are"special "data information" used in EHS. I will skip the details egarding OWNID (and why this parameter exists) here (please check e.g. SAP EHS -BD online help); e.g. check here:
Example: Transfer File for Specifications - Basic Data and Tools (EHS-BD) - SAP Library
One threads (created by myself) might be helpful as well: Issue found in EHS in using specification data import using process
Check e.g
for other threads if additional problems might come up
IN your case. Proposal is you must identify one "valid" ownid. and maintain customizing parameter
C.B.
Ps. "The log shows the error message as "Parent object contains error" is "referenced as error message in the document as embedded
