Delta vs Initialization

[Former Member]

Hi everyone,

I am posting a topic here regarding the Delta update. Before doing a Delta,it should be initialiazed first. I have a doubt here how the system knows before the delta it's already initialized. i.e any information regarding initialization and delta stores in the tables, i am confusing here. Please give to me your valuable replies

Thanks and Regards

Hi,

The init timestamps are saved on source system in table ROOSPRMSC. The selections (if any) made in the init request are saved on source system table ROOSPRMSF. Every delta load time stamp are saved in a table for the individual data source. One example is BWOM2_TIMEST (co line items).

Hi Satya,

Delta process must be initialized (full load + system setting) before any delta load.

All the delta details stored in the table <b>RODELTAM</b>. Table <b>ROOSOURCE</b> gives the delta type for each data source.

Thanks Rohini, You mean the system will check the database tables whether initialization done before Delta or not right?

The tables mentioned by Rohini contain only meta data for the data source such as supported delta type and so on. If You want to know whether a concrete init has been done look at the tables in my previous posting or go to the init package and try initializing. The system will tell you, that you cannot init with overlapping selection if an init already exists.

Yes PR is right. Time stamp in the table ROOSPRMSC in the source system should match with time stamp in the table RSSDINIT in BW for successful delta load.
