If in test, go to /SAPAPO/MSDP_ADMIN, check your planning area, right click on the same and delete the time series object (in background). Once done again right click and click this time on create time series object (in background). Thereafter take a consistency check in SE38 with /SAPAPO/TS_LCM_CONS_CHECK.
I hope this would resolve your issue.
