We often find questions related to Backflushing & COGI errors (Errors in Automatic Goods Movements during Confirmation entries). Let's recollect certain Basic details -Goods movements can be created during the confirmation entry for the Production/Process order. Backflushing

If you confirm an order / operation with components that have the Backflushing indicator set, the system automatically posts a goods issue for these components. For more information about the Backflushing indicator, refer to the end of this section.Automatic Goods Receipt

If the control key of the operation being confirmed specifies automatic goods receipt, the system automatically posts the produced material to stock. Automatic goods receipt can also be activated by the production scheduling profile.

o Automatic goods movements are not permitted for materials that require serial numbers. However, if an automatic goods movement is specified for a material that requires a serial number then an error record is written. This error record can be displayed using the reprocessing function but it cannot be posted. Error records for materials that require serial numbers must be deleted manually. The goods movement must then be executed manually in inventory management.

Backflushing IndicatorWe can control backflushing in the following objects:

Material master - Backflushing key (MRP2 view) Work center - Basic data screen. This is only taken into account, if the

material master stipulates that the work center should determine whether the material is backflushed. Work centers are assigned to a production order via the operations. The operations are copied from the routing used.

Routing - component overview. This indicator is always taken into account, irrespective of the indicators in the material master or work center.If the Backflushing indicator has been maintained in the master data, it is copied from there when you create a production order. You can change the indicator in the production order Incorrect Goods MovementIf errors arise  during a goods movement for certain reasons(for example, during backflushing insufficient stock is available in the warehouse) then you can either process the incorrect goods movements directly in the confirmation transaction or separately using a reprocessing function.

  Correction in the confirmationo In Customizing for Confirmations (OPK4 - Goods movements indicator

in the Error handling/logs area) you can define that, for individual entry of confirmations, the system displays an error log before it saves a confirmation with incorrect goods movements. Before you save the confirmation you have the option of correcting the incorrect goods movements.

Correction when reprocessingo If you want to process incorrect goods movements at a later stage, you

can use the reprocessing function (COGI/CO1P) The table AFFW shows the list of Goods Movements with Errors from Confirmations We can clear many of the regular errors by setting up a batch job to run the program CORUPROC at defined frequency.Still, we need a regular manual intervention to check to clear the residual errors using transactions COGI (or CO1P), left behind after the batch job execution. This is an attempt to prepare the list of Common errors seen in COGI and respective resolution actions. Kindly feel free to suggest changes / additions to the list. Listing few of SAP notes which could be useful reference, while analyzing the Goods movement errors -

 While searching around, found another nice blog   on COGI, by Tanya Duncan. Sure, many would find this an useful reference as well. Thanks.Senthil

Q1) Explain the Functionality (Usage & Limitations) of T-code COGI

Ans:

COGI transaction code used for Automatic Goods Receipts - Error handling for Backflush materials. 

Backflush means: Determines whether the back flush indicator is set in the production order. Here, a 3-level hierarchical logic is applied: 

1. In the routing, the backflush indicator is set in the component assignment. 

2. In the material master record, the backflush indicator has the characteristic "Always backflush". 

3. In the material master record, the backflush indicator has the characteristic "Work center decides", the indicator being set in the work center. 

We use COGI to check & clear error record occurred during backflushing or automatic goods receipt.

When we use auto GI (Backflush) & Auto GR in production order then sometime some goods movement may will get failed due to some reasons. So at that time these failed goods movement records will be captured by system & can be viewed in COGI transaction.

You can check detailed description of error by individual record here & can reprocess it as per error.

Transaction: COGI

Q2) Difference Between COGI & MF47 

I can find post process record occurring due to back flush problem such as component shortage or storage location and so on. But there was nothing when I used COGI. I checked the table AFFW for COGI, no records. What is the reason?

Ans:

To use COGI in REM  Activate "Create Individual postprocessing records" check box at rem profile SPRO IMG Reference Settings. 

Now you can see the Error records at COGI same as MF47. 

As you know, COGI has some more features. But if you clear/delete the record at MF47, the same will be deleted/cleared at COGI also.

Transaction: MF47
