SSAS Processing - Process Add after Process Clear

Hi Experts,

I have a requirement of Process Increment the SSAS Partitition after the Process Clear command. How can I do this? SSAS does not allow me to 'Process Add' after the partition is 'Process Cleared'.

I cannot do Process Default or Process Full after Process Clear because it will add all the data from fact table into my cube. I want to add chunk of data from my source into the cube after the partition data in cleared.

I am using SSAS 2012 Standard Edition.

Please advice.

Thanks,

Ruchika
