hi all

plz tell me the importance of 4 mrp views in material master.

how do the system know that avail check is based upon ATP

Dear Anil singh

Your question is too large to explain. However, in nutshell, I can brief about MRP views.

MRP1 - In this tab, you are defining whether the material is relevant for MRP, if so, who is the MRP controller, what would be your lot size etc.

MRP2 - In this, you are defining whether the material would be procured externally, or only inhouse operation or both, time taken for inhouse production, number of days for GR processing etc.,

MRP3 - In this, you are defining which strategy you should adopt whether make to order or make to stock, whether the availability check should be based on daily requirements or individual requirements etc.

MRP4 - In this, you are defining the production version of that material, allowed percentage of scrap that occurs during production of the material if the material is a component, whether the material is a repetitive manufacturing or not etc.

With regard to Availability Check, there are three types of availability check:

a) Check on the basis of the ATP quantities

b) Check against product allocation

c) Check against planning

In Customizing, you determine whether an availability check is to be carried out against the ATP quanitity or against planning. The check against product allocations is controlled in the material master and elsewhere in the system.

Check on the Basis of the ATP Quantities

The ATP quantity (ATP = Available To Promise) is calculated from the warehouse stock, the planned inward movements of stock (production orders, purchase orders, planned orders) and the planned outward movements of stock (sales orders, deliveries, reservations). This type of check is performed dynamically for each transaction, taking into account the relevant stock and planned goods movements with or without replenishment lead time. Planned independent requirements are not taken into account here.

Check against Product Allocation

Product allocation facilitates period-based distribution of products for certain customers or regions. As of Release 3.0F, you can carry out an availability check against product allocation. This ensures, for example, that when production is low, the first customer does not get the full amount, resulting in following sales orders not being confirmed or being confirmed far too late.

Check against planning

The check against planning is performed against independent requirements which are usually created for an u2018anonymousu2019 market rather than being customer-specific (for example, in the strategy u2018Planning without assemblyu2019, when production occurs only up to the stocking level). The planned independent requirements result from demand program planning and are used for planning expected sales quantities independent of orders

Dear Laxmipati

Thanx for reply

my intention was to understand once we enter the materials in the order the system does availability check rite how does the system know that the check is based on ATP or product allocation.where exactly is the control.

if the control is at material master level then plz tell me for Atp which fields are enough to maintain in mrp views and i wud appreciate if u cud tell in laymans language

Hi anil

In the schedule line , VOV6, there will be thee check boxes at the bottom , where in the first two are related to TOR and availability check and the last one is related to product allocation

So if you activate that check box also , product allocation gets activated

This is where we control the availability check and product allocation

Yup,

Schedule lines Availablity check and TOR tick and the schedule line determination of Item category and MRP Type.

Thanks,

Dear anil

When you create sale order, system will always give first preference to your schedule line category, as for as availability check is concerned. Go to VOV6, select your schedule line category and under the tab "Transaction flow", you can see three fields. If you select the box against "Availability", system does Availability Check whenever you create sale order.

The second preference will be given to your item category where also the control is there. Go to 0vlp, select your item category and there, you can see a field on right side "AvailCkOff". If you maintain blank here, system will check at the time of delivery creation also.

thanks

Dear Lakshmipathi ji.,

Greetings and Respects.

When ever MRP1,2,3, is talked about, every one talks about whats in the screen but no one says what that particular screen is talking about, I mean the subject it is covering. Some one told me every screen is trying to cover one different topic. Can you tell me more on that??

Great to hear from you as always!!

Good day!!
