i want to know the details about the following
In Lo data extraction,the flow is like this
1.RSA3 for extraction
2.from RSA3 to RSA7
3.RSA7 to BWi.e PSA
4.From PSA to Cube.
If this is correct,when we face data load falilures,we have to check RSA3,RSA7,PSA,CUBE.
My question is what are the possible reasons for the failures in these places and what are corrective actions we can do.
i.e. whts the problem if data does not come to RSA3 and what actions we can do.
whts the problem if it comes to RSA3 but doesnt come to RSA7. simillarly...
i will be very much thankful to you if you could give me a detailed explanation.
If there is any related documents or blogs available pls let me know.(i already have Siegfried Szameitat blog but i think is not sufficient enough).
Also go through this link for step by step procedure
hope it helps..
