Hi Experts,
We have the requirement to enable delta mechanism in DS while extracting data from SAP BW active data tables and loading into DS Staging area Oracle db.
Ex:
Day 1 - Active data table in BW
| Sales order Number | Sales order Item | Material | Created Date | Amount | Quantity |
|---|---|---|---|---|---|
| 0000048635 | 100 | JS-NETDIR | 07-NOV-13 | 10 | 20 |
| 0000048635 | 101 | SVC-JS-NETDIR-1Y | 07-NOV-13 | 20 | 30 |
| 0000049272 | 100 | CHAS-BP-MX480-S | 08-DEC-13 | 3 | 1 |
First day when we run the DS load we got all the 3 records from BW to DS Staging.
Day 2 - Active data table in BW, we have few records modified and added as highlighted below in red and blue.
| Sales order Number | Sales order Item | Material | Created Date | Amount | Quantity |
|---|---|---|---|---|---|
| 0000048635 | 100 | JS-NETDIR | 07-NOV-13 | 10 | 20 |
| 0000048635 | 101 | SVC-JS-NETDIR-1Y | 07-NOV-13 | 30 | 90 |
| 0000049272 | 100 | CHAS-BP-MX480-S | 08-DEC-13 | 5 | 6 |
| 0000000343 | 10 | 45W4541 | 20-AUG-13 | 5 | 7 |
| 0000000428 | 30 | DR74X | 27-AUG-13 | 3 | 23 |
| 0000000938 | 10 | CHAS-BP-MX480-S | 01-OCT-13 | 10 | 34 |
So when I run delta on 2nd day only it should load the 5 records i.e. changed records (2 Highlighted in Red) and newly added records(3 Highlighted in Blue)
Please suggest the ways how the delta extraction can be enabled in DS while extracting from SAP BW.
Thanks & Regards,
Raju.
