Hi,
We are planning to implement datasource 0FC_BP_ITEMS for Open and clear items.
I just wanted to understand how this datasource delta functionality works.
SAP has mentioned how we can implement delta. The process is as below. But didnt mentioned how delta works here.
If you want to use the delta method, you first have to activate it in the Implementation Guide for Contract Accounts Receivable and Payable under 
Integration 
Business IntelligenceMaintain Central Settings in the clients of the OLTP system.
Can some one help me in understanding how the delta works for this datasource i.e Delta enable field, delta logic and all
Thaks & Regards,
Anand
