Back Flush Compared to Manual GI

Question

Hello,
I am comparing the pros & cons of Backflush with Manual GI to suggest the suitable solution .. the points that I could think at top of my head are as follows ..
Back Flush
Pros
Minimal human intervention
User's with limited understanding can function
Faster goods issue process
Cons
Large cumulative variance in system & actual stock figures over  time in most cases
Not Recommended for high value material
Salient Feature: Suggested for low cost & less critical BOM components where there is not much financial/ logistic impact with variance within tolerances.
Manual GI
Pros
Accurate consumption can be   captured
Better actual & system inventory figure sync
Accurate inventory figures enables better requirement planning
Cons
Recommended for matured users
Labour intensive (Manual activity)
Demand discipline in terms of reporting the consumption error posting due to stock deficit etc
Salient Feature: Recommended for high price & critical BOM components where consumption needs to be captured more accurately.
Please suggest your views on expriences across differrent clients ...

Dear,
Apart from Bcakflush and manulgood issue please check this also, Good issue can be done through MB1A, COO1N, CO15. CO27.
Transactions CO27/COIK are lists, based on the order information system, whereas Transaction MB26 is reservation-based. However, it is also possible to make an order-based selection in Transaction MB26 using the 'Production order' selection window. In this case, both lists should also issue the same components for identical orders.
  In the event of incorrect goods movements in Transaction COGI, picking using Transaction MB26 generates postprocessing records, whereas Transactions CO27 and COIK send an error handling. If the goods movements cannot be corrected, the records are returned unchanged.
Picking using Transaction MB26 can be scheduled as a background job.
This is not possible with Transaction CO27/COIK.
  In Transactions COIK/COHV, you can use mass processing to store goods movements of the picking as future change records and you can then update them later using a report (for example CORUPROC). There is no function of this type in Transaction MB26.
Coming to your pron and cos,
In backflush you need to use the program  CORUPROC to update COGI or terminted inccoreted good movement through OPK4.
Else it is very eassy process but 311 you need to use for transfer from the Ware House to Production stroage loaction.
Unplanned good issue you need to define in confirmtaion screen but there are chances of miss mach of quantity due to manual entry. So here you need screen control.
In correct good issue you need to cancle the confirmation but in Manual good issue you can do it seperatly.
But in manual good issue it is possible to confirm the order without good issue.
Hope it will help you.
