I'have currently a very big flat file imported from SAP-BI Reports as csv .
Now we plan to update my file with a "Delta" from the SAP-Cube.....every days (-> smaller csv file).
With 4 key-references, I can classifiy the "Delta" lines i receive with the exisiting file :
- Delta line not correspond to an existing line = new line
- Delta line correspond to an exisiting line = Change
But, a always find 2 "delta" lines for an exisiting line, with some negativ value, or missing value.
So my questions :
What are the rules in SAP to generate a "delta" ?
How to define whitch value must be added, or deleted, or stay unchanged from the 2 "delta"lines ?
Thanks for helping....
