MFBF Related

I have 4 materials for which i am doing assembly backflush (131) but my stock is not getting updated i.e. on doing 131; qty of assembly is not getting increased but at the same time my components under it are getting consumed (261) and this is ultimately creating a variance????????

Why is this so?? Please let me know the reason behind this...

Also tell me the TCode which shows that whether we have done an assembly backflush or activity backflush or component backflush...If it exists; please tell...

Moreover please tell me that when we do reversal for an assembly; does it reverses all activities and components or only the assembly???

Answers shall be definitely rewarded

Hi Vicky

while carrying out MFBF have you ensured flagging "assembly Backflush"?

check whether you are using reporting points ; if you do RP backflush then only GI and activity posting will take place and GR for assembly will not take place. only for final operation, GR will take place. so check while carrying out MFBF ensure "RP backflush is not flagged".

check your control key assginment in Rate routing for Auto GR flagging.

then check your REM profile assigned to the Assembly for MVT types and for GR at final reporting point flagging if you use RP.

if all this are ok then GR should take place for sure.

When you carry out the reversal, the full backflushing document (which acts as a bracket around all the individual documents) is flagged as reversed, along with the following data:

The goods receipt is reversed and the accompanying material document and full backflushing document are indicated as cancelled.

The goods issues for the components are reversed, that is, the component quantities are posted back.

The activities are reversed.

Depending on your settings in the repetitive manufacturing profile, the system proceeds as follows to cover the reversed quantities:

The system either creates a planned order for the reversed quantity.

Or, it activates a single-item planning run which creates a planned order that corresponds to the possibly changed planning situation.

Or, the system does not create a planned order in which case the planner has to check the situation.

The basic dates are determined for the newly created planned order.

If you set the system to create an individual document for each backlog in the repetitive manufacturing profile, then the system deletes the corresponding individual documents and adjusts the quantity accordingly in the cumulative log document. Moreover, postprocessed backlog postings are reversed.

The Logistics Information System is adjusted.

In the separated backflush, the planned order is increased by the corresponding reversal quantity.

In the separated backflush, the reversal of a goods receipt is no longer possible if the goods issue has already been carried out.

Partial reversal with adjustment of individual components

In some areas, for example, chemistry, it can make sense to backflush required quantities in advance, without naming specific quantities. The actual quantity used is only measured after production, using precise measuring equipment. The required quantity must be corrected afterwards.

To do this, you can carry out a partial reversal with adjustment to individual components. In the initial screen for backflushing, choose Document-neutral reversal. The system automatically switches the movement type to the reversal movement type if you have made the corresponding settings in Customizing.

hope this helps

Hi Ganesan

Many thanks for your detailed reply.....

I just now want to know that is there any check which can show that whether we have RP Backflush? Or which can show that only assembly has been backflushed or only activities have been backflushed??

Hi vicky,

That you can check with MF12. Access this report with Plant/material/Posting date ->in Document number coloum, u can find Processing Type letter like Z(RP back flush) , B. it will give type of backflush has been done for that material Number. For help press F1 by selecting letter.

Hi,

when you do backflush, a document will be posted. you can see document in T.code MF12. By tracking this document Number u can see the Movement type through which material has posted.

Do u mean to say, ur having 4 header material, it has some components, when you doing assembly backflush for each header material GR not done (131).

please letus know are u getting any error message while doing backflush.

please check your REM profile, GI bckflush at GR posting check box has been checked . and also check 131 movement type has been defined in Rem profile under the Movement type Tab.

Hi Pradeep

I can see in MB51 that 131 MType has been done for thes 4 FG Materials...

But my stock is not getting updated.....i.e. no effect of GR....but for thes 4 FG; components which are below it are getting consumed (261)....and because of which there is a variance...between debit and credit

I want to know that why is so?? This has never occured before?

Hi Vicky,

Have you checked with inspection stock for your material.please check the same in MMBE. It might be posted to inspection stock if material has QM view.

We dont maitain QM view? My issue is that where has the material been posted?? Because in system it shows 131 only...

But note that there is a material wherein it has been reversed also i.e 132 M Type; has been done but there is a gap of 10 days between 131 & 132....

Is it the cause of this issue or related to something??

Dear Vicky,

I hope you are not carrying Reporting point backflush,If my assumption is

right,please check the various stocks in MMBE T code.

Check with this & revert back.

Dear Sir

I am not doing RP Backflush.....My case is that (for one material) 131 M Type was done say 10 days back...and thereafter it was reversed i.e. 132 (and there was a gap of 5 days between 131 & 132)....

On reversal i know that everything will be reversed but i am not able to find my FG material stock? i.e. where this has been posted?

Even in REM Profile there is no such setting made that what to do when we do reversal?

while reversal FG stock should be reduced and a planned order will be created for that quantity.

do you your FG stock is not getting reduced when reversing?

Hi All

Many many thanks to all for your efforts...

Lastly tell me that when we do reversal; do activities also get reversed? I think i am stuck up here.only...According to me it should be reversed; but it is not getting reversed and so leading to variance? If reversed; how do i check..

Please reply and thereby i shall close this thread.....

Dear Mr.Vicky,

When you do a reversal using MF12,(assuming that for the document

GI,GR,activity posting was doneusing MFBF)then the activities are also rversed

and this cost gets reduced from the activity cost in the product cost collector.

The same can be checked in KKF6N.

<b>A planned order will get created automatically only if you have done the

settings in REM profile under the control data 2.</b>

You will get the follwing message after doing reversal in MF12(assuming for a

normal REM profile,standard cost estimates)

<b><i>

Material movement with document 6000001068 and activity posting reversed

Message no. RM196</i></b>

HI Vicky

as per my knowledge

when you reverse Backflush activity also reversed provided you are reversing in the same period and settlement posting is not yet carried out!.

if product cost collectors are settled for the period then the activity may not get reversed.

You should reverse before cost settlement!
