Error message in update rules - 2LIS_03_BX

Hi,

I am using the datasource 2lis_03_BX in standard mode & succesfuuly did the transfer rules assigment with the Infosource 2lis_03_BX, but when I try to do the update rules mapping for the Inventory cube OIC_C03 cube I get an error message which says "No update exists for time-reference characteristic 0CALDAY". Therefore none of the KF's get mapped. Can anyone please help me with this? Did anyone face this issue, please let me know.

Thanks in advance!
