ATP & MRP Areas

[Nansy_Matary]

Hello all , 

Scenario is like this , i have plant with different MRP storage locations areas , stock now separated with different MRP areas , the issue is when i try to run ATP in sales order if i mention the storage location the system will look only to the stock in related to MRP area for this storge location and if i didn't mention the storge location in sales order the system will look to the stock in the plant excluding all MRP areas

is the there is way to run ATP in sales order in plant level with all the stocks in all MRP areas as well , or a way to run ATP with group of MRP areas in the same time ?

Thanks,

Hi @Nansy_Matary ,

the MRP areas are exactly to do a separation of stock/supply/demand elements, putting them 'together' is not a goal of the MRP area.

However, you can use the Alternative-Based Confirmation (ABC) capability to check ATP in multiple storage locations during sales order processing and come up with a confirmation that consists of one or multiple storage locations. An example: Example: Substitute Storage Location Determination

Andreas

Bear in mind that Alternative-Based Confirmation is part of aATP (advanced ATP), not standard ATP.

Thank you both for the feedback @Dominik_Tylczynski @Andreas_Krause1 , i have configured ABC and function still not working in sales order availability check , my question now is i activate ABC in availability checking group x and i assign material type in this availability checking in plant level , and i assign availability check x in material master is there is difference between availability check in material master and availability checking group or how the system determine this availability checking group in sales order to run ABC during ATP check

You can activate ABC via customizing, see https://help.sap.com/docs/SAP_S4HANA_ON-PREMISE/f132c385e0234fe68ae9ff35b2da178c/645bf9254eaf47bbaf2... .

Hello @Andreas_Krause1 i activate it but when i check the log i have this message "Sources are not configured for Line Item /000010 Product xxxx "

Hello,

I suppose you have activated SBC by mistake. Please deactivate the SBC flag for the checking group:

SPRO

Advanced Available-to-Promise (aATP)
Configuration Activities for Enhanced Check Methods
-> Configure Enhanced Check Methods by Document Purpose

and check again.

--------------

If ABC is not being executed somehow -> please review the checklist of question 1 of KBA 2776851 FAQ: Alternative based Confirmation (ABC) with aATP.

Hope this helps.

best regards,

Michael

Hello @Michael_ATP , Thanks for the feedback , the flag is deactivated and the system anyway didn't allow both flags to be activated together

Hi Nansy_Matary,

from the error message it seems that somehow SBC is being active. Its either a bug (in that case we need to investigate the issue via SAP support case - please create a new case if required) or perhaps one of your substituted products has SBC active. Verify the possible substitution material/plant combinations and verify the assigned checking groups for SBC activation.

best regards,

Michael

Hello @Nansy_Matary 

That is how ATP with MRP areas work - see the note 3512644 - ATP Check with MRP Areas and Storage Locations for details. I don't think you can customize that or have ATP across a group of MRP areas.

Best regards
