How Delta in standard extractor works?

[Former Member]

Hello

I want to understand how delta in standard extractor works. Imagine I upload data from standard extractor to ODS.

I have the following records in ODS

key value

A 10

B 20

C 30

I have the following records in R3 side

key value

A 10

B 555

C 30 (deleted)

D 200

Questions

1. will delta delete the record with key C?

2. will delta change the record with key B?

3. imagine I deleted all data from ODS. Will delta bring changed records (with key B, C, D) or all records

POINTS ARE GUARANTEED!

Hi dear,

here are the answers:

1. usually you will find C (it still exists) marked as deleted in one specific atatus field (0ITEM_DEL or something similar) dedicated to this purpose (so, if you want to do not report on these records, it's enough to exclude what have got 'D', for example, in this specific field)

2.Sure, system will upload two records:

B -20

B 555

3.If you delete everything (included init request) from your ODS you will not be able to upload delta anymore...

Hope it helps!

Hi,

The delta process is a feature of the extractor and specifies how data is to be transferred. As a DataSource attribute, it specifies how the DataSource data is passed on to the data target. From this you can derive, for example, for which data a DataSource is suited, and how the update and serialization are to be carried out.

The type of delta process affects the update into a data target. When you update data in an ODS object, you need to serialize it so that you can also overwrite it. According to the delta process, the system decides whether it is necessary to serialize by request or by data packet.

If a record is deleted in the R/3 system it wont get..

Delta brings the only changed or new added records..
