Delta management for 2LIS_04_P_MATNR Datasource

Hello,

I need to use 2LIS_04_P_MATNR that extracts quantities and dates on production order at header and item level.

This Datasource works with ABR delta method.

The dataflow from 2LIS_04_P_MATNR supplies data direct from the Datasource to an Infocube.

I need to extend the structure to supply other data of quantity and date type at order header level that are not supplied by 2LIS_04_P_MATNR.

I will make an extension to create and supply those aditional fields to the extraction structure of 2LIS_04_P_MATNR.

My question relates to the delta management with LIS structures.

If changes occur in R/3 on those aditional fields I added in the extraction structure, does BW generate the corresponding Before and After Image so that loaded data in the Infocube are coherent?

ex: at creation 100 for Division A, added characteristic = date 01/01/2006

I modify the date to 01/02/2006

at modification do we receive in BW -100 A 01/01/2006 and +100 A 01/02/2006

or -100 A 01/02/2006 and +100 A 01/02/2006

If the answer is no, what is the best solution in terms of modeling?

I saw the following solution : by using use an ODS between Datasource and Infocube. This would ensure data coherency linked to delta management.

Are there any other?

Thanks for your help.
