Back flushing

Dear Sneha,

Backflush Definition:

The non-manual posting of an issue of components some time after their physical withdrawal for an order.

The goods issue posting for backflushed components is performed automatically at the time of order completion confirmation.

Backflush in Discrete Scenario:

Backflush is nothing but the automatic Good's issue of the material at the time of order confirmation.

It means consumption posting of the components has taken place in order to manufacture a product.

261 movements happens for the backflushed component's,for this you have to set the indicator either in

the material master (MRP 2 view or else in the work center or else in the routing).

If you are using Discrete concept means then this setting has to be made manually in any one of these fields and in the case of

REM scenario no need to set this indicator in either of the material master or else work center or else in rate routing.

If you are not going for backflush concept means then you have to issue the matertials to the order manually using the T Code

MB1A .

REM scenario:

Let us Assume A is the header material and it requires component's B and C to produce it.

So after producing A,while confirming in the T Code MFBF for A,the component's B and C get's consumed(nothing but Good's

issue) so A will get posted for 131 movement that is Good's reciept and 261 movement for the component's B and C that is

good's issue.

Again in REM scenario there are 3 types of backflush,

1.Assembly backflush(normally GR,GI and activities are posted - 131,261 and activites are posted) or vice versa like 132,262.

2.Component backflush(normally GI alone happens - 261/262 happens)

3.Activity backflush(only the operations are posted)

All these backflushes are performed using MFBF/MF42N.

Check and revert back.
