Pull List and Stock Determination inProduction

1. Pull List

The pull list controls the in-house flow of material for supplying production with materials. The system assumesthat the components required for production have already been produced in-house or procured externally andare now available to be transferred from their current storage location or bin to the production storage location.The pull list checks the stock situation at the production storage location and calculates the quantities ofmissing parts. Replenishment elements can be created for these missing parts.

2. Master Data

Here we are going to review the key master data needed to use the Pull List.

2.1. Production Storage Location

Issue location for production order

Number of the issue location from which the material is issued during the production process. Backflush isposted to this issue location if required.Use

In production, this is the access sequence in which the determination of the production storage location occurs:1. First, the issue storage location of the material to be issued (MARC-LGPRO) is transferred to the

material master from the MRP data if it isfilled.

2. The system overwrites this value with the issue storage location from the bill of material (RC29P-LGORT, STPO-LGORT) if it is filled.

3. If the operation to which the component is assigned in production order contains a work center withsupply area, the storage location is transferredfrom this supply area (PVBE-LGORT). However, this transfer is only carried out if storage location data(MARD) is maintained for this storage location for the material.

Pull List and Stock Determination in Production


Depending on if your component is used in more than one production storage location, you could asisgn this inthe material master or in the BOM or through a Supply Area. Let's supose in this example that we assign this atBOM item level.

This is maintained using t-code CS02. The production storage location is assigned at item level. Once you arein the BOM, click twice on each BOM item and go to Status/Lng Text tab:

2.2. Stock determination

The pull list controls the in-house flow of material for supplying production with materials. The system assumesthat the components required for production have already been produced in-house or procured externally andare now available to be transferred from their current storage location or bin to the production storage location.This automatic transfer between the current storage location to the production storage location is performedbased on the stock determination strategy.



Strategies for Stock Determination

You make all the settings you require for a stock determination strategy.You determine a strategy at plant level using the stock determination group and the stock determination rule(The terms 'rule' and 'group' correspond to the checking group and the checking rule logic in the availabilitycheck).

The customizing point for the Strategies for Stock Determination is:SPRO --> Materials Management --> Inventory Management and Physical Inventory --> Stock Determination --> Define Strategies for Stock Determination

The stock determination group is assigned to the material in the material master record.



3. Pull List Execution

Suppose your business is running the following process: Create and Schedule process orders: the planner creates the process orders and the production

scheduler schedules all the process orders. Material staging: warehouse responsible will receive the list of process orders and will move

components to the shop floor based on: which is the material that will be produced and which is theproduction line capacity.

Production execution: production responsible executes the production of the corresponding processorder.

Goods receipt & confirmation: finished good production quantity is received and the confirmationis done. At this moment components are consumed from the production storage location usingBackflush.



3.1. Create and Schedule process ordersLets create a process order and ensure the Production Storage Location is determined asexpected.

Take a look of the component list. All the components have an assigned production storage location:



3.2. Material staging (MF60: Pull List)

The warehouse responsible will move components to the shop floor (production storage location). This can bedone based on process order number or entering the material and quantity to be produced (this is commonlyused when the order takes several days and we only want to supply components on a daily basis for thecorresponding production of the day)In this example suppose that the first process order is: 304472 and its duration is 5 days. The correspondingfinished good is: 403403 (production version: 0001) and the production line maximum capacity is 5000CS/day.Material Staging is executed thru transaction: MF60.



The pull list checks the stock situation at the production storage location and calculates the quantities ofmissing parts. Replenishment elements can be created for these missing parts (this is the section at the bottomof the screen).

Let's see what is each column: Issue stor. location = production storage location. This was entered in the bill of material. NetReqQty = component quantity based on maximum production line capacity. In case the Pull list is

executed agains an order, here you will see the quantity of the component determined in the order. Available stock = this is the available stock in the issue storage location (production storage

location). This can be the available remaining quantity of the before production day or shift or order. Quantity staged = NetReqQty Avail.Stock = This is the remaining quantity to be moved

to the shop floor (production storage location). RepLoc = is the warehouse storage location. It is the location found by the stock determination

strategy.

Finally.. you press Save and the components will be moved from the main warehouse to the production storagelocation

4. Pull List Global SettingsIf necessary, limit your selection using the Global settings . Here, you have the choice between:



General settings

For example, you may choose to display components with missing quantities only in the pull list or, using theindicator Take all requirements into account , you may define that the system is to include the requirementsof all orders that influence the missing parts situation. If this field is not selected, the system only includesrequirements for the specific order that you entered in the missing parts calculation. Here, you can also definewhether your components are staged at storage location level via direct stock transfer, or using stock transferreservation.



Settings for dialog controlHere, you define which procedures are to be carried out automatically in the pull list and which are tobe carried out in dialog mode.

You also define whether the system is to save a complete log of all the messages and whether this log is to bedisplayed automatically.



Printing settings

Here, you make the settings for the print list.
