Material Determination and MRP

[Former Member]

Hi All,

In the material determination screen ( VB11), in the details screen, a check box for MRP has been provided . The documentation says that the system uses this in MRP run, to generate subitem of the alternate material, in case the the requirement of original material can not be fulfilled.

Howevr the scenario is not working for us. Can any one throw more light on this.

Does this require any more settings?

Regards,

hi,

Here the Text from Glynn C Williams ..

you can find the thing/ requirement from here..

Source : Glynn C Williams SAP Hand Book

When using material determination, you may enter the material to be swapped

in the standard Material Entered (MatEntered) column of the sales order. However, when using the customer material information record, you can only enter the customer’s material in the customer material field of the sales order. Thus, should you be using material determination to propose automatic swapping of the customer number automatically one to one, be careful not to use the customer material information record, as this may confuse the user as

to where he should enter the data.

Note The automatic substitution that happens in the background only occurs according to the availability check (if you select a subitem). Thus, should you

have four products for the system to do a automatic substitution on, and you have stock of one of them and not the other three, the system will propose and consume that one for which you have stock. This can cause problems due to

the fact that if this one material is procured correctly, due to it having a demand on it to be consumed, it may be automatically filled up, causing a continual

circle where only this material is used and the other three are not consumed.

Unfortunately, you are in a bit of a predicament as the pop-up box for manual selection only offers the material numbers and not the available stock on hand. Thus, it is impossible for the user to make an informed choice as to which material to use. Apparently, from Version 4.5 onwards, SAP will show the available stock in the pop-up box for selection. However, the ABAP code is

very integrated and not worth moving into a previous release, such as 4.0.

The outcome column enables you to decide whether or not the proposed item from material determination should automatically replace the existing material or if it should be displayed as a subitem in the sales order.

Remember that if you use the outcome subitems, be sure to configure your item category determination correctly. That is, the main item that is being substituted should have the product selection higher-level (PSHP) item as the usage indicator, and the subitem material being displayed as a subitem should have the usage indicator PSEL.

Thanks Praveen,

But this doesnot talk about MRP. My question is related to MRP.
