Hi Dennis,

Thanks for the detailed mail. I applied the back flush indicator on RM and performed the testing. It went very well. All RM were posted automatically with the first operation. However, i couldn't underatnd the last portion of your mail in which you explained the FG posting automatically during last operation with ruting control. do i have to check the back flush indicator in the FG master data and also the last work center operation OR any other way.

Thanks & Regards
Tehseen

Hi Tehseen,
Actually all of this is master data settings. You are correct about
setting the backflush indicator on the MRP2 view of the raw material.
You can set it to 1 which will cause the system to backflush 100% of the
time when that material is used OR you can set it to 2 which will cause
the system to use the backflush indicator in the work center. The
backflush indicator on the work center is located in the general data
view. This works well when the raw material is not always backflushed.
Materials must be assigned to operations; but if they are not assigned,
the system will default the assignment to the first operation, which in
most cases is the operation you want to backflush raw materials. If it
isn't, then you need to assign the raw material to the operation you
want it be backflushed. Also the production storage location on the
MRP2 views controls the storage location the material is backflushed
from. Set the desired backflush storage location on the raw material as
the production storage location. Set the desired goods receipt location
on the manufactured material's MRP2 view. I strongly suggest you create
a separate backflushing location for your raw materials other than the
primary storage location. I know it means an extra material move
transaction, but it keeps the backflush bill of material variances into
one location and makes them very visible.
The GR is a function of the routing control key. I pretty sure the
system comes standard with PP03 as the routing control key that has auto
GR. If not, you will have to configure a copy of PP01 and set the auto
goods receipt in the control key detail.
Good luck

Thanks Dennis,
This sounds appealing. I would like to implement your way of working in
my quality server. Would you explain further what steps/changes do i
have to make in order to see the effects. What i have understood is that
mainly i will have to activate the backflush indicator in the Raw
materials MRP view 2. But one thing i would like to understand from you
is that how can we link GI with first operation and GR with the last
operation. Does it require major configuration ?
Basically i am an SD consultant but do have to support on PP/MM as well
in my company. I am not familiar with PP configuration but have slight
idea.

Tehseen,
We are using a discrete manufacturing model and we have simplified the
goods issue and goods receipt process by implementing backflushing on
the first operation with the confirmation. We have implemented the
goods movement (GR) with the confirmation on the last operation. The
accuracy of this process is dependent on the raw material allocation in
the bill of material. In our process this works very well.

Hi,
We are in a discrete manufacturing industry. Basically we manufacture
cartons (Packaging industry). Our implementation is simple and the
process flow is like after creation of production order, the store has
to issue raw material by MB1A, mov type 261, than follows the labour
confirmation CO11 and finally the FG posting by MB31, mov type 101.
Backflushing is not active.
What i have noticed is that standard SAP alllows to post FG even if raw
material has not been posted.........which seems to be a loop hole in
the process flow. Because, only at the time of month end closing
reports, we come to know that raw material has not been posted. So i
thought of applying an error check at the time of FG posting.
Or, can i handle this by activating backflushing ?
The whole idea is to post raw material correctly and than post FG

If you are using repetitive manufacturing to report finished goods
production then you can set the Error Correction for backflushing. You
need to select Execute correction in Dialog mode and make it mandatory.
This will require you to either recieve the necessary raw material first
or change the components being issued to process the backflush. Nothing
will go to the reprocessing log.

Dear All,
I would like to know that is there any way that i can block finish goods
posting if Raw material posting has not been made.
The point is while posting finish good, the system must give an error
message that Raw Material postings are pending.
Appreciate your response
Thanks & Regards
