Day’s supply in MD04.

Hi MRP Expert;

In MD04 in collective access, the list of requirment shows three columns:

• Stock Days' Supply Without Receipts
• First Receipt Days' Supply
• Second Receipt Days' Supply

I wanted to manually check the results for an article by applying the principle explained in the SAP help, I did not lead to the same results.

Is it possible to detail me how do the calculation. The objective is to set up alerts based on these values for the MRP Manager.

Here is an example vith list and détails

Thanks in advance
