Where can I find out what the rules are for extracting Purchase Orders?

Hi all,

Relating to BI 7.0, ECC 4.6

From a business perspective we are looking to be able to identify ALL the rules/criteria for Purchase Orders when they are extracted in ECC to BI.

The datasource is 2LIS_02_ITM

For example deleted PO items are not extracted to BI, nor where LOEKZ (Memory flag =X).

In brief there is criteria that identifies which PO items are extracted.

Where can I find out what ALL of these conditions for extraction are?

I have looked in the extractor program MCEX_BW_LO_API and there is a class for filling the a table but I cant see any criteria here to how it decides WHAT to extract i.e where in the code the criteria is set.

Also this of course could be set in customizing somewhere?

Anybody know where?

Thanks in advance.
