Populate missing data in cube

Hi Experts,

This is the first time I am posting any question.

I am currently working in sales cube. Delta Data from billing item ( Data source 2LIS_13_VDITM ) is scheduled in process chain and has been working fine for last 3 months. Every day in morning 5 A.M scheduled job fetches data from SAP/r3 and posts it to BIW cube.

One day on 5 dec 4 pm by mistake i initialized the info package in update mode " Initialize without data transfer ". so the next day when the scheduler fetched the data biliing documents created between 9am to 4 pm on 5 dec wa missing from the cube. Help me populate these data without breaking the delta.

One more thing I dont have a DSO ie data is going directly to cube from PSA.

Thanks in advance.
