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.

Hi muhsinoztas , I am new in MRP, Can you please let me know where to check the planned order marked constant? and to active regenerative planning?

Hi,

Have you checked whether the plan order number range was nearly exhausted.?

Try updating the number range for object PLAF and recheck.

Also refer the note 531599.

As I have observed, when planned order number range interval is reached near exhaustion /N/AFS/MD02 run will be completed without an error but will not generate planned orders.

We increased number range but still same issue

You can check if the planning file was correct for the material not generated PR, because I come across the planning file be not correct before.

And you can try to set a Planning file batch job (t-code: MDAB) before running MRP, although the Planning file will be created when the MRP running.
