Hi

The backflush can be simply done by setting field 'Backflush' in the material master (MRP View 2), you can decide if the backflush can be always happen on the component or it idecides by the work center. (Work center also have the same field.).

Best Regards.

Dear Geetika,

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 .

This can also be set at routing level or individual production order level for the components or else for an order type at

confirmation parameter's level in OPK4 check the setting for all components.

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.All this depends on the REM profile settings in OSP2.

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.

Dear

Backflash can done based on the following set up :

1.In material master MRP2 view of the item , Backflash field should be kept -1-Alaways back Flash

2.In work Center where the routing operations are done , -Goto-Basic Data View -Back Flash Indicator -to be marked .

3.In routing Componenet Alocation -Item Line -Back Flash Indicator to be ticked once assinged to a particualr operation .

Priority will be always Work centre even you keep the Material master MRP2 view kept always back flash .

Dear

Backflush is nothing but Automatic Goods issue to a production order. It can be configured in such a way that once the Operation is confirmed (eg. lets say by CO11N) the materials that are assigned to that particular operations are automatically issued to the production order.

Below are the settings you need to maintain.

a) Material Master MRP 2 View ( either 1 or 2 based on your business process)

b) Work Center Basic Data View tick the backflush indicator

c) Routing against the operation bakflush indicator has to be ticked

Hope the above helps.
