AFS MRP Error

[Saif_Dew]

We are facing a problem on AFS MRP run. After certain period of time suddenly MRP not generating any planned order. After investigating that all the relevant master data are correct, there is no changes in customizing, sales order requirement available, stock not still produce, planning file are correctly maintain, number range also not reach at target level. 
After several attempt of trying solve the problem we still not get any rote causes.

I am  not getting where the missing point of not generating any requirement

Hello Saif,

Firstly, Could you check availability check in SD/GEN view. When the fields is empty , planned order wont be update.

Secondly, you can check "The reason for rejecting a sales document"

Finally you can check requirements type in procurement type, you have to determine this requirements type according to your strategy.

Hi muhsinoztas, I have check as per your advice but all the relevant data are correct, Can I debug standard transection?

[muhsinoztas]

Saif in my opinion debugging standart MRP should be last solution way. İf there is no suitable solution absolutely yes you can.

Could you check the planned order marked constant ? If you are using MRP Live you can try regenerative planning.
