availability check of sales order in planning strategy 40

[Former Member]

Dear friends,

Kindly help me this query:

From online SAP help in Demand Management, it said in planning strategy 40:

"An accurate availability check is performed according to ATP (available to promise) logic during sales order processing. The system checks whether sufficient planned independent requirements have been planned to cover the sales order.... If there is insufficient coverage of components (the sales order quantities exceed the planned independent requirement quantities), the sales orders cannot be confirmed"

According to above paragraph, I think that availability check of sales order is carried out against PIR, if PIR quantity cannot cover sales order quantity then order will not be confirmed, it also means stock on-hand will not be included in availability check. However, my testing reveal a different conclusion: sales order is confirmed against stock on-hand, not PIR. My questions are:

1/ in planning strategy 40, how does system carry out availability check for sales order?

2/ how to interpret above help from SAP?

I got that help from this link: http://help.sap.com/saphelp_erp60_sp/helpdata/en/cb/7f9b7043b711d189410000e829fbbd/frameset.htm

Many thanks for your clear answers.

Regards,

Duc.

Dear,

thanks for your very quickly reply. However, I've already read your link and it made me more confused.

In your link, it clearly said "It is possible to confirm any quantity up to the stock quantity according to the ATP checking rule" --> Sales order is checked against stock according to ATP logic, which confirms my testing result.

Then how can we understand the first help: "The system checks whether sufficient planned independent requirements have been planned to cover the sales order... If there is insufficient coverage of components (the sales order quantities exceed the planned independent requirement quantities), the sales orders cannot be confirmed"

SAP help clearly states that If indicator for Avl chk is not active then only sales order will be confirmed against Planned independent requirement.

Dear Duc,

IF my understanding is correct,then there are 2 different types of availability check methods

1.ATP Check - Available to Promise check normally used during production order processing.

2.Check against the PIR's(Planned Independent Reqmts) which is used in the planning strategies 50.52,60,63 and 74(All the

other planning strategies uses only ATP check).

now check and confirm this.

Dear Mangalraj,

If planning strategy 40 uses ATP checking logic, then what SAP said on its help is conflicted with its own saying? or what mentioned in first help is incorrect? I do want to know the meaning of the first help. Could you please clarify?

Duc.

strategy 40 has requirements VSF and KSV

for KSV the corresponding class is 50

in define procedure by requirement class you can see that availability chck is enabled for 50

sales orders are checked with checking rule A

the logic used can be seen for the combination of checking group coming from material master and A

dont take help.sap too literally, it look like its mostly translated from German

you can say that PIR include procured or produced quantity too

Dear duc pb ,

In 40 its only ATP that works.

you can do another test ,

Create PIR 15 quantity.

Create a stock of 10 quantity.

and now create a sales order firszt of quantity 30, as both of the above after combining cant fullfill this demand, save order run MRP.

system will create orders against PIR (15) and remainibnbg quantity of sales order (5)

run one more test, by creating PIR 15 quantity , no stock and a sales order of with quantity 10.

share your findings.

Thanks
