back flush means automatic goods movement if set back flush indicator in mrp-2 view what will happen in real time, in how many places we can see back flush

Back flushing is nothing but automatic goods issue. System will automatically posts the goods issue when you confirm the operations.You have no need to make manual issue. It will reduce the effort.

Backflushing is automatic accounting (Goods issues - 261 mvt) of material consumed for production, at the time of confirmation. Eg. When a 4 wheeler automobile is rolled out from assy line, 4 wheels & Tyres are deemed to be consumed and issued to production order automatically by way of backflushing by the system.

Assembly line picks the material from stores/ Assy line and use.

No Physical issue & Manual posting ( Goods Issue) by Stores.

Backflush is used for material which are a must and having fixed relationship.

This can be configured in MRP2 Screen,Work centre, Routing and production order.

Each has some special function.

If you configure this in routing or production order you have no need to activate this in MRP2 or Work center screen.

MRP2 Screen defines whether material components are backflushed are to be made at the work center.

Hi Venkatesh,

Backflush indicator, as you rightly said, is used to facilitate automatic goods movement of materials.

In SAP, backflushing can be carried out in 4 ways:

i. Material Master-MRP 2 View

ii. Work Centre- Basic data

iii. Routing-component assignment

iv. Production Order- Component overview

Out of the above 4 options, material master takes the highest priority if the backflush indicator is set at multiple places.

An example would be as follows:

You have defined in MRP view-"Workcentre decides whether to backflush" and have also checked the backflush indicator in Workcentre basic data tab.

Also, in routing, the backflush indicator is not ticked. But still while carrying out the confirmation of the operation to which the material is assigned in routing, automatic GI (backflushing) will take place since the system gives priority to the setting in material master and not the routing.

Hi,

Using backflushing, you can automatically post goods issue based on confirmation. The backflushing indicators are available in master data such as material master, work centre, routing and in configuration of order confirmation parameters.

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

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

- Also, in the material master record, the backflush indicator has the characteristic "Work center decides", and hence the indicator being set in the work center.

Hope this will help.

In master data level you can   maintain the bakflush, In Material master MRP 2 view( backflush is applicable for the material), Work center ( backflush is applicable if you use this workcenter irrespective of material) , Routing ( for the particular production line only)

while creating a production order system will set the backflush in  production order based on the above setting

Otherwise in config level

you can set the indicator goods movement all components in OPK4 ( confirmation parameter)

this setting will bring the components in confirmation screen * this setting will applicable for all materials in plant for the order type)

Hi V,

   BF Means-Automatic goods issue posting.

    you may select BF in sap in 4 places.

01- MRP2 View in Material master

02- Work Center

03- Routing

04- Production Order

If you select in MRP 2 view-then automatic goods issue for that particular material(if you assign this material to 03 nos bill of material then for all the BOM it will be auto GI.

Thanks
