How is 'summary update' working

Dear all

I am wonder how is the ‘summary update’ working beneath the path ’

Accounts payable > Purchase order > Setup > Summary update

You mean when you update the purchase order or from the parameters - it is not present in the menu defined. Look at the summary update tab in the parameters and then the button, you select how to “group” purchase orders into less documents than 1:1 per order dpending upon the fields selected and the processing options chose. As examples:

None - No summary updates are processed. One Purchase order journal will be created for each Purchase order.

Invoice account - Use this selection to summarize multiple Purchase orders into one Purchase order update.
