Can we change material availability date in Sales order Item level -> scheduling line -> Shippingtab

[SAPlearner7861]

Hi All

Is there any way in standard to change the material availability date in past ( where stock is available in MMBE) in SAP sales order. 

Please suggest .. I tried but failed to change the material availability date.

Best Regards

Hi 'SAP learner',

When we talk about Material Availability Date (MBDAT), we talk also about scheduling. Once you entered a requested delivery date for the schedule line, the scheduling calculated multiple dates, also the MBDAT.

From what I understand, you have stock physical available in the warehouse and you would like to get it confirmed today. My first question would be: Do you use ATP to get reliable confirmations? If the answer is yes, that it can indeed be that although you have stock physical available, you do not get a confirmation for today (MBDAT =  today). Reason is simply, that you have promised the material already for a concurrent demand. ATP helps you to prevent over confirmation situations.

To see what you have really available, please use the app Monitor Product Availability (co09).

Can you please spend some words on how the situation is in your system, to be more precise, how it is with the material? Do you use ATP?

Regards,
Andreas

Yes we use ATP .. but my basic understanding is why dont we Over write these dates .. Please refer to F1 Description of field Material availability date .. SAP saying that we can change the date manually ( This is misleading )

[Andreas_Krause]

You can change the date if you do not check ATP and do all the confirmations manually. But I would like to understand the motivation behind the manual change. It seems there is an unexpected result from the calculation. Can you elaborate a little more on the concrete example and the expectations you have when it comes to confirmation?

And I marked Availability check as KP ... in This case also i am unable to change the material availability date ... So is ther any way ( SAP note , Standard way) to change the material availability date in standard way?

[SAPlearner7861]

Hi Andreas .. I have changed availability check = KP ( no Planning ) , Shipping point definatio = no Lead time , no Route = No Lead time... Still I am unable to change the 'material availability date'. ( It is depending on RDD Date, based on RDD automaticaly Material availability date determined) but when I try to change -2 days then system throwing an error material availability date is in Past.

Hi 'SAPlearner',

Again, I do not understand why you want to put a MBDAT that is in past. We have today 26th April. If you have a MBDAT today, that means you have x pieces that are available today, hence a person can go to the shelf and take those x pieces for further logistic processes. What is the meaning to put MBDAT to lets say 20th April? This date is in past, you cannot travel into past and do the logistical steps?
What do you want to achieve from business perspective?

Andreas
