Hi,

1) BOM status must be active in the BOM header data.(CS01)

2) BOM usage must be relevent for production. (OS20)

3) BOM explosion indicator must be enabled for MRP (OS23).

4) Selection of BON ID must have BOM usage indicator assign (OS31).

Apart from the above settings MRP4 view of BOM explosions must meet the selection criteria like BOM selection by prod lot, or if you maiantain prod version then seelction by prod version etc, other wise BOM will not be selected.

During MRP run if if you have planning mode 1 "adjust basic dates" then BOM will not be exploded for the existing planned orders/PRs...only if you have new requirements. With planning mode 2 and 3 BOM always exploded.

Hi Gide,

Also please check that the BOM Lot Size " From" & "To" is matching your requirement quantity.

Hi Mr.Gide,

Let me tell you some reasons,which's because of the <b>settings in front end.</b>

<b>1.The BOM's valid date might be a reason.

2.The BOM's status might be made inactive.You can make it inactive by clicking the header,and changing the BOM status to 2.

3.If you are using ECN,With release key for BOM's ,if it's not released BOM will remain invalid.</b>

Thanks & Regards

Hi,

For Bom explosion to takes Place first the Bom Status should be active for

Mrp.

In OS23 check whether MRP Explosion check box is

enabled.

Bom item shouls have valid area and period of validity.

Bom components should be relavant for production

We have to maintain selection id for priority for bom usage in define order of priority of Bom Usage.

Hi Gideon,

For the BOM status MRP explosion should be selected for bom to explode.

The BOM must be valid on that particular date.
