EKBE table for Generic Delta

Hi Gurus,

Good Day to all. I just like to inquire some details for creating generic datasource with delta enabled. I have created a view table with fields from EKBE table, and created generic datasource that reads the view table I have created from EKBE, now it needs delta process with CPUDT as delta specific field name, seeing the data type of CPUDT, it is DATS with 8 length.

I would like to assure if what will be use as marker of delta, timestamp utc, timestamp local, calendar day and numeric pointer?

And if I use one of the above, what settings that needs to be use for the safety interval upper and lower limit?

Thank you for your inputs and really appreciate it.
