Periodic Lot Size and TLB

[Former Member]

Hello!

I have one article with a periodic lot size of 2 days.

However this morning, in the TLB proposal appear this:

Req.date	Avail.date	Quantity
2014.11.06	2014.11.17	80
2014.11.07	2014.11.18	40

This mean, load day per day.

In SNP appear this:

SNP	Unit	16.11.2014	17.11.2014	18.11.2014	19.11.2014	20.11.2014	21.11.2014	22.11.2014
Total Demand	TRP		21	21	21	21	21	21
Distribution   Receipt (Planned)	TRP					40
Distribution   Receipt (Confirmed)	TRP
Distribution   Receipt (TLB-Confirmed)	TRP		80	40
Total Receipts	TRP		80	40		40
Stock on-hand	TRP	52	111	131	110	129	109	88
Supply   Shortage	TRP
Safety Stock	TRP
Target Days´   Supply	D	4	4	4	4	4	4	4
Target Stock   Level	TRP	82	103	107	111	115	119	99

Question: Why TLB propose to load in 2 following days? As far as I know, if this article has a periodic lot size of 2 days, the system should propose to load every 2 days,

Thank you very much in advance for your help,

Hello Julia,

For this SKU try to run SNP heuristic using time bucket 2 days! Also you could try to force the system to create at the beginning of the time bucket the receipts by using period factor (tab Lot.Size -> Quantity and date determination). Select check box USE PERIOD FACTOR and in the Period Factor field enter 0.1 as value.

"

The system determines the exact availability date/time of the receipt elements

within a period, by adding a time interval (that it gets by multiplying the

period factor with the period length) to the start time of the period. You can

enter a factor between 0 and 1, where 0 is the start of the

period, 0.5 the middle, and 1 the end of the period."

Hope that help you.

Thanks.

Hello Marious,

Thank you for your answer.

As far as I know, time buckets determine the display horizon, and I don't want to change this.

The point is that according with this answer:

Periodic lot size of 2 days should group my dependent requirements and create a requisition every 2days.

However, this doesn't work: I have a requisition every day, instead every 2 days,

I would like to know why,

I hope you can help me,

Thank you very much in advance,

Hi Julia,

The time bucket determine the time bucket period planning and the display! You can do monthly, weekly or daily planning. The monthly plan can be displayed in week/day time bucket for example.

In your case with daily time bucket the heuristic will plan on each day, either if you have period lot size 2 days.

If you want to work with daily time bucket a solution would be to have 2 days as Good Issue processing time. For this in the product master, tab GR/GI enter in the GI processing time field  2 days. In this way you will force the system to postpone the each requisition with 2 days. 

Thanks.

Hello Marious,

Thank you for your reply. However I want to work with daily time bucket. And GI won't solve the problem: I would continue having requisitions every day, no every 2 days.

What I want is to group my dependent requirements and create a requisition every 2days.

To do this, the solution would be using periodic lot size of 2 days, Am I right?

However, although I have periodic lot size of 2 days, system create a requisition every day, so I am lost.

I wonder if you can help me,

Thank you very much in advance,

Hi Julia,

Did you try GI = 2 days? Sorry but I don't have another idea.

Maybe someone else can help you!

Thanks.

Hi Julia

Have you managed to resolved this issue?

It looks like TLB-confirmed orders are created every day?  Is the Distribution Planned/confirmed created correctly after the Heuristic run?

There are many possibilities to manipulate the results.  You can either try creating a Shipping Calendar only 2 days per week, or rolling 2 days and try that.

Also, check on the Deployment/TLB run what data view/bucket is being used, daily buckets or weekly buckets? It should probably be on a weekly bucket for the period lot size to create every 2 days.

Hope it help you.

Hello Frans,

Thank you for your answer.

Periodic Lot Size of 3 days should create a requisition every 3 days.

However, in TLB appear a requistion for every day

Example of TLB:

Req.date	Avail.date	Quantity
2014.11.06	2014.11.17	80
2014.11.07	2014.11.18	40

My question is Why?

I hope you can help me,

Hi Julia - sorry I don't have a solution for you.

I came across this BADI which should be worth a try.  If I am correct it is called during the SNP heuristic run.

/SAPAPO/SNP_PERIO_LS

If you find a solution, please let us know.

Thanks
