This function is for all companies without APS License.

What does Available-to-Promise System (ATP System) mean?

A available-to-promise (ATP) system is a system that helps companies anticipate demand and match it to their peak production and capacities. Using a ATP system allows a business to create a balance between what it can produce and what customers and clients are requesting.
ATP is a global way of looking at demand and capacity. The system takes into consideration a lot of factors including raw materials for products, inventory, transportation. Considering all these, the ATP system helps to deliver accurate predictions for a given company.

You can access ATP in SAP Business One if you do not own an APS License by opening a Sales Order/Sales Quotation > right-click on an assembly line:

For further details on differences between Capable-to-promise (CTP) and Available-to-Promise (ATP) functions, see CTP vs. ATP in previous chapter.

For Configuration See Configuration Wizard > Sales

The Beas ATP:

- Creates a forward calculation for the assembly.
- Checks availability of resources and material for the complete order-related sub-structure of the assembly.

- Displays the possible delivery date.
- Displays material- and resource information needed for this assembly.

What you need for using CTP:

No APS License
Correct planning data inside the system
Actual MRP

Limitations

The ATP uses the Default MRP function to calculate lead time.

It is a resource planning tool.

The ATP cannot determine the actual delivery date. It is only an auxiliary tool for the seller.

The ATP

- Ignores Variants (Formulas and Scripts), Configurations and Precalculation, but supports Short Variant (A-Z) and Item Version control.

- Ignores formulas inside Bill of Materials and Routing positions.

- Ignores routing related Bill of Materials Positions.

- Ignores resource reservation from other sales order if work order does not exist.

- Material check is based on last MRP run and it does not check the actual material situation.

Before you start:

•	ATP can deliver correct information only if all data are correct.

•	Define a default MRP (see Configuration wizard) and calculate this every day.

•	Calculate work orders every day and use forward calculation. See APS. If resource reservations are in the past, the result cannot be correct.

For more information on the complete process see CTP.
