Transfer of PV to APO as PPM

Hi Team,

       I am trying to CIF a PV from the R3 to the APO. While activating the Integration Model for "PPM", the entry gets stuck in the queue with the message "Validity intervals for Product  in  ->  overlap" of the Function Module "/SAPAPO/CIF_PPM_INBOUND".

      When I ignore the above message, the Integration Model for PPM in the R3 becomes Active. But, when I check in the APO system, I do not find the PPM transferred.

     Please help me regarding this issue.

     Thanks in advance for the help and for your time.

Thanks & Regards,

Srikanth.
