Dear Manoj,

As you know, ATP is a big subject & some times its difficult to point the exact problem.

In your case, I suggest you to execute the function module:BAPI_MATERIAL_AVAILABILITY using Tx:SE37

key in selection criteria , in results check the "ATPQTY"- it will show you how much actual stock is available for use i.e. ATP qtty.

still if you find the availability & system not confirming the qtty, then problem could be in checking rule

Tx:OVZ9 check in relevant combination, whether you are considering RLT or not?

is this case with MTS or MTO

because in Sales order -

for MTS - checking rule "A" & MTO checking rule will be "AE"

Hi,

Check the following settings:

1. Check the MRP type in materail master and availabilty check field in Material master MM02.

2. Check the schedule line category VOV6

3. Check the Requirement type under procurement tab in sales order and check the Requirement class Settings (OVZG)

4. Check your credit limit and check Block quantity confirmation in delivery blocks in OVZ7.

Finally check CO09

Hi,

When ATP calculates , it checks many other factors such as

Current stock + Incoming Stock - Outgoing Stock.

Current stock = Un-restricted stock + Safety stock*

Incoming stock = PO stock + Shipping notifications + Planned / Production orders

Outgoing stock = sales orders + Open deliveries

You have to check many other factors as well.
