Hello,

Can anyone post a rough walk through on how to configure ATP in SD? Thank you

hi,

ATP: stands for Available to Promise. It is the process of checking the available quantities of a material. The ATP quantity is equal to warehouse stock plus the planned receipts (incoming stocks). ATP takes in to account all movements into and out of the warehouse. If selected, it can check the stock examined for ATP that can be safety stock, stock in transfer, stock in quality inspection, & blocked stock, although the planned receipts & planned issues of the stock associated with ATP may be purchase orders, purchase requisition, planned orders, prodn orders, reservations, dependent reservations, dependent requirements, sales requirements & delivery requirements.

If a sales order is created, there is no available stock, and the ATP check is set to include RLT, the system will automatically confirm the desired quantity for the end of the RLT based on whether the material is externally or internally procured. It will still give a confirmed date according to the end of the lead-time. Should there be partial stock available, the system will confirm this partial stock available, the system will confirm this partial qty and move the remaining qty to the end of RLT. Thus it does not do an availability check outside RLT. If the RLT is three days for a specific material, it will not do an availability check outside of those three days, as it automatically thinks that it will definitely have the stock on the fourth day.

Hi,

ATP checking is maintained for the combination of checking gruop and checking rule..

checking group is maintained at material master sales / plant view.

checking rule is assigned to transaction internally...

for the combination of these values we are maintaining what stocks need to be included and what stock are need to be excluded... from the inward movements like Purchase order, PR, production order and outward movements like sales order, delivey.

IMG -- SD -- TOR and availability check..

Pre request for the availabilty check..

1. Availabilty check will be activated at scedule line level and requirement level..

2. Plant must be assigned to the line item...

3. TOR must on at req class level

we can run the availabilty check at sales order and delivery...

Req class is responsible for delivery check and schedule line is responsible for order level...

req class will be determined from req type and req type willl be determined from stratogy group or the combination Item cat + MRP type...
