hello John,
Back here to update the solution :
SAP analyzed the issue and informed that it was an error due to wrong data .
Searching the Table RSHIENODETMP with the latest dataload RNR we found that there were some nodes without IOBJNM filled and which caused the message " Infobject is not Available Error in Infopackage .
After we corrected the DATA file , we were able to upload the Hierarchy successfully.
Best Regards
Ram
