PRC: Distribute Supplier Cost Adjustments Accounting

Hi All,

I just want to understand how the Accounting entries will be picked up for the adjusted supplier/Expense costs which are interfaced to projects.

For Example there is supplier Expenditure A against a project from Account payables for AP invoice.we will do adjusting to the invoice in AP and these adjusted costs will be interfaced to projects.we will running "PRC: Distribute Supplier Cost Adjustments" in projects to get this costs distrubuted and accounted.

Could you please give me the idea how the accounting will happen for the orginial transaction and adjusted transaction.it would be great if you can give the Autoaccounting  and SLA standard rules name from this accounting.
