Hi Ashfaq,
1. Inconsistencies listed as " Entry only in livecache" after run consistencies check will be deleted after you mark them and run correction.
As the pegareas entry existed only in liveCache you will not find them in the table /SAPAPO/PEGKEY of the SCM database.
2. The question on what application created those. I recommend to run the check in //om17 after the job or application/CIF run, which change the product, and see if the inconsistencies reported.
3. Create the SAP message to SCM-APO-MD-PR component and get SAP support/hints to resolve the case.
Thank you and regards, Natalia Khlopina
