Actual BOM Of Material Ledger

Former Member

Hi,

I have a question about the actual BOM which is displayed in the material ledger CKM3N view using the hierarchy button with title "Actual BOM (Procurement Alternative)".

I believe this BOM is the one which is used in the cost estimate of the material. However during the actual production if some different material components are used which is not listed in the initial cost estimate BOM, how material ledger is going to display this change of components? Will it display the changed new components in its actual BOM display?

1) If it will, then why the system is not allowing me to display the actual BOM per production order in ML? Because when i place my cursor in the production order row and click actual BOM, the system asks me to position the cursor in the process category node level which is displayed as "Production". Hence looks like i can see the actual BOM at the root node level for all production orders, if this is the case how am i going to see the change of material components (if there is any) by the individual production orders? Because the change of material components may happen for each production order separately.

2) Alternatively if it will not display the change of material components which are different from the original cost estimate BOM, then how will the user know what is the actual BOM structure used in the production when they are in the material ledger CKM3N view?

Hi,

ML builds the actual BOM purely by actual material movements like consumption to production orders and goods receipts from production orders. That means for your questions:

Will it display the changed new components in its actual BOM display?

-> yes, if these components were posted

why the system is not allowing me to display the actual BOM per production order in ML?

-> ML collects all the info on the level of procurement alternative, not by individual production order. So you will see a summarization over all production orders in the period assigned to the same procurement alternative, which is typically defined by the planned output material.

Hi Udo,

Thanks for your answer. However since each production order can consume different kind of materials other than what is mentioned in the BOM, i believe end of the day each production order's actual BOM will be different from each other. Hence how can i see the actual BOM by production order wise in the CKM3N screen?

Secondly going by your own explanation, if the actual BOM can only be displayed by the procurement alternative why the valuated quantity structure cannot be displayed by the procurement alternative? I noticed the valuated quantity structure can only be displayed at the FG material level and not by the procurement alternative level.

Anyone knows the answer for my last question?

I noticed the valuated quantity structure can only be displayed at the FG material level and not by the procurement alternative level.

this is not the case. Of course you start CKM3N with a finshed material, but in the BOM hierachy the next nodes under the material are procurement alternatives, marked with the blue trapezoid icon with the + in the center.

I only assume in your implementation all production orders will be assigned to the same procurementa alternative, so you see only one.

Hi Udo,

I just need one final confirmation from you as follows :-

Say for example i have the following :-

Output material : M001

Production order : P001

BOM structure : INPUT_MATERIAL_1 and INPUT_MATERIAL_2

Production order : P002

BOM structure : INPUT_MATERIAL_3 and INPUT_MATERIAL_4

In the above situation when i go to actual BOM at the material/plant controlling level in the ckm3n for the output material will i see the following :-

Output material : M001

BOM structure :-

INPUT_MATERIAL_1

INPUT_MATERIAL_2

INPUT_MATERIAL_3

INPUT_MATERIAL_4

The answer is by default yes.

BUT: if your production orders are so different, you might have different production versions in the order, that determine e.g. the BOM found in PP.

And in material ledger configuration you can set the controlling level to differentiate between production versions or by BOM and routing:

With that you would see separate actual BOMs for both orders.
