0FC_BP_ITEMS: ERP customizing and delta mechanism

Question

Hi BI fans
I have two questions:
1.) The following link describes how to make the settings for delta enabling of datasource 0FC_BP_ITEMS:
http://help.sap.com/saphelp_nw70/helpdata/en/27/42073e774a4329b6dd6bab21eef613/frameset.htm
Prerequisites-
"...If you want to use the delta method, you first have to activate it in the Implementation Guide for Contract Accounts Receivable and Payable ->  Integration Business Intelligence -> Maintain Central Settings in the clients of the OLTP system..."
But I cannot find the setting for "Maintain Centrall Settings" in the implementation guide!
Any idea from your side?
What I see are entries for:
Define Fields for the Extraction of Items
Define Grid for Grouping of Items
2.) What is the exact delta logic of this extractor (working through function module)?
Which fields are relevant for the delta logic?
Thanks

Hi Andrea
First of all I activated the whole content (datasource, BW content, etc.).
Regarding the pseudo-delta on CPUDT I have designed a BEx variable on a DATS 8 time characteristic, e.g. 0NETDUEDATE. It is a BEx variable feeded by a customer exit, you will find a sample coding below. Furthermore an interval variable, mandatory input.
Screen for BEx variable properties:
Assign this BEx variable into your infopackage for intended use of pseudo-deltas, type OLAP-variable:
The sample coding below gives you an idea about our pseudo-delta mechanism, from 1st. of last month until sy-datum.
Data wa1 like line of e_t_range.
data d1 type d.
data fdate type d.
data fyear type d.
data ldate type d.
data fmonth type d.
case i_vnam.
when 'ZL2MTDY'. "BEx variable on 0NETDUEDATE or any other DATS 8 time characteristic
d1 = sy-datum.
fdate = d1 - 31.
fdate+6(2) = '01'.
ldate = sy-datum.
wa1-opt = 'BT'.
wa1-sign = 'I'.
wa1-low = fdate.
wa1-high = ldate.
append wa1 to e_t_range.
ENDCASE.
