Hi Reddy,
Replenishment lead time (RLT): is the time taken for the material to become available either internally (in house production) or externally (from a vendor). The most important things to consider during an external procurement are purchasing and MRP 2 (procurement) views of MMR where the processing time for purchasing, planned delivery time and goods receipt processing time are taken into account. On the other hand internal procurement is based on in house production time (MRP 2 view) goods receipt processing time or alternatively RLT time, which is found on MRP 3 view.
RLT (Replenishment Lead Time) is the time taken for the material to become available. RLT is only used when doing an ATP check (Available To Promise). The value of RLT for a material is specified on material master record.
There are three types of availability checks –
Check on basis of ATP quantities.
Check against product allocation.
Check against planning.
Configuring Availability check through Checking Groups –
1. The checking group + checking rule determine how the availability check is to be performed.
2. The checking group determines whether and how the system checks the stock availability and generates requirements for material planning. The checking group defines what type of requirements will be passed on i.e. summarized requirements (daily/weekly) or individual requirements for each sales order.
3. The checking rule applies to how the availability check is to be carried out at the transaction level. Note that you must define checking rules for each individual application such as for production orders for example. In Sales and Distribution, the checking rule is specified internally within the system and cannot be changed.
4. The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts and issues are to be included in the availability check and whether the check is to be carried out with or without the replenishment lead time.
5. Briefly explaining the above – checking group determines which type of requirement to be passed on to MRP whether it be individual or summarized and checking rule which is at the transaction level and can be configured independently for each application module, determines which stocks, receipts and issues to be taken into account. For performing an availability check checking group has to work in conjunction with checking rule.
6. Advantages of individual processing over summarized processing –
Backorder processing is possible.
You can access (MD04) order, line and schedule line individually which gives a greater control on available stock and requirements placed on stock.
The system automatically uses individual requirements in case of special stock items.
7. Required data for the Availability check to be carried out –
The Availability check must be switched on at the requirement class level.
The Availability check must be set at the schedule line level.
A requirements type must exist by which the requirements class can be found.
A plant must be defined in the sales order for each schedule line item (in other words plant must be defined for every material in MMR).
A checking group must be defined in the material master record in the MRP3 screen in the availability check field.
8. Configuring Availability check and defining Checking Groups –
Checking groups are introduced into the sales order based on the setting in the material master record.
SAP standard checking groups are 01 – summarized requirements and 02 – individual requirements or you can create your own by copying the standard ones.
Total sales and total deliveries columns are there to configure a checking rule to sum up requirements to post to MRP either individually or by day or week.
Block quantity required can be set if you want several users to be able to process the material simultaneously in different transactions without blocking each other.
The no check indicator is CHECKED when you DO NOT want the system to carry out ATP check.
9. Defining material block for other users – the block check box is an indicator that enables you to block material master records of a particular material during the availability check and restrict other users from accessing same master record and reserve the material. If the block is not set, two users can confirm the same material at the same time for two different orders, not knowing if the stock is available or not. If you select this field, the material is blocked during the availability check and other users cannot: a) Make changes in the material master record. b) Create purchase orders for the material. C) Create orders for the material.
10. Defining default values for checking groups - Checking groups are introduced into the sales order based on the setting in the material master record.
However if there is no entry present in the material master record for the checking group, a default value can be set here, depending on material type and plant.
This default value will be used by the system depending on the material type mentioned in MMR and plant in sales order.
If an entry exists, this default value is over written by MMR.
11. Controlling Availability Check – in this section, you tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check in addition to whether or not to consider the replenishment lead time.
12. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sales and distribution transaction.
13. These settings carry out control both for sales order and delivery as well. This is due to the fact that you may want to include specific stock or incoming stock for the sales order, yet at the time of the delivery only include physical stock on hand waiting to be shipped.
14. It is possible to indicate to the system that you would like the availability check NOT TO CHECK the stock at the storage location level. This indicator is used to set the scope of the availability check.
15. It is used to switch off the check at storage location level. You create a reservation for a particular storage location. However, the scope of the availability check is set in such a way as to exclude the storage location. In this case, the system carries out the check at plant level only and does not take the storage location into account that is specified in the reservation.
16. Should you not want the system to automatically check RLT, you may indicate so here. RLT is the time taken for a material to become available. It is only used when doing an ATP check and is taken from MMR.
17. Defining the elements in the availability check entirely depends on the business needs, but a few tips are given under –
When controlling the Availability check at the time of the sales order, a purchase requisition does not necessarily indicate by it is going to come into the plant.
A shipping notification on the other hand - a confirmed purchase order – is a good indicator of receiving stock on a specified date.
It is always recommended not to select the shipping notifications for the delivery requirements type as you may not actually receive the stock into plant or warehouse for which you are creating a delivery.

Hi,
Replinishment Lead Time is the time taken to produce the goods or to procure externally. It needs to be maintained in the material master MRP view.

Hello Reddy,
Replenishment Time (RLT) is the time which we use to know that in how many days a material can be produced or can be procured in the store house.
We can do ATP in two ways one without RLT and other without RLT.
ATP with RLT: If RLT is considered the Availability is only checked up to the end of replenishment lead time. If the material availability date is calculated on the basis of the current date to lie after the replenishment lead time for the item, the item itself can be confirmed despite insufficient stock being available. In this case, the system assumes that any quantity requested by the customer can be procured by the material availability date and considers the goods to be available. Therefore, a binding confirmation can be sent to the customer.
When we create an order for a part, in which the replenishment lead time is not to be taken into account in the availability check, the system can perform an unrestricted availability check. The quantity can only be confirmed on the date on which availability can be guaranteed again as a result of planned inward movements of stock. In this case, system only confirms whatever the stock available on customer requested date.
Below Example will explain the different scenarios:
Scenario 1: Availability check including Replenishment Lead Time (RLT):
Order Quantity of ABC : 500
ATP stock is : 200
Requested Delivery date : 8.10.2007
Planned delivery days in material master: 10
Availability check indicator : with RLT
In this scenario, system will confirm the stock of 200 on 08.10.2007 and for the remaining quantity it will consider the RLT and confirm the stock after 10 days i.e. on 18.03.2007.
Scenario 2: Availability checks excluding Replenishment Lead Time (RLT):
Order Quantity of ABC : 500
ATP stock is : 200
Requested Delivery date : 8.03.2007
Planned delivery days in material master : 10
Availability check indicator : without RLT
In this scenario, system will confirm the available stock i.e. 200 on 8.10.2007. System will not be able to confirm the remaining quantity because; it does not consider the RLT.
Hope it helps.
Regards,
Priyanka

15. It is used to switch off the check at storage location level. You create a reservation for a particular storage location. However, the scope of the availability check is set in such a way as to exclude the storage location. In this case, the system carries out the check at plant level only and does not take the storage location into account that is specified in the reservation.
16. Should you not want the system to automatically check RLT, you may indicate so here. RLT is the time taken for a material to become available. It is only used when doing an ATP check and is taken from MMR.

When controlling the Availability check at the time of the sales order, a purchase requisition does not necessarily indicate by it is going to come into the plant.
A shipping notification on the other hand - a confirmed purchase order – is a good indicator of receiving stock on a specified date.
It is always recommended not to select the shipping notifications for the delivery requirements type as you may not actually receive the stock into plant or warehouse for which you are creating a delivery.

Hi Reddy
Time taken to produse the goods inplant,or time taken to
procure the products externally from the vendor. these
settings are in MRP views of Material master data.
Total replenishment lead time s the time, in workdays, that it will take before the material is available to be used or sold. This field is not a system calculation but should be the sume of the total in-house production times and the planned delivery times. This field should be entered if the planning department wishes it to be part of the availability check
Reward if useful to u

Hi,
RLT is time taken to produce or procure the stock to fulfill the sales order requirement.
The important set up is
a) In automatic configuration setup, activate RLT box
b) In material master, if the material is externally procured (Material master -
Mrp 2 - procurement type is F), assign value (no. of days) to the field of GR processing time and planned dly time)
c) In materail master, if the material is internaly produced(Procurement type is E), assign the value to (no. of days) the field inhouse production date.
Hope this statify you, you yourself do some r&d to know what setup we need to do when a material is both way of procurement?
Reward if my answer given you atleast basic info about RLT

Replenishment Lead Time is the duration required to produce the stock for saleability.
Replenishment Lead Time can be configured in the Material Master in the MRP3 View. Further information will be given if this is what you wanted.
Reward points if this helps.
