Backflush automatically sends the necessary component parts to supplier so that user can receive the main part without doing that. If this is not selected user needs to manually do that.

(in Supplier Material flow it is necessary send the component parts to supplier in advance in order to receive the final part from supplier)

Hi @Sandamini Wijeratne ,

 

When you use ‘ Backflush’ below is the way application works:

Example:

  1. Create a PO

 

 

  1. Backflush has activated and the location entered is a location where the component part exists (component part has a qty of 91 )

Qty per assembly = 2, PO qty (purchase part) is 3 and therefore the total qty needed from component is 6 

  1. What happens when the backflush check box is selected is that these components do not require any reservation or picking to be done in the supplier material window; they will be automatically issued at purchase order receipt of the purchase part or top part.
  2. Release the PO
  3. Register Arrivals window → Receive 
  4. PO will be received

If you check the Inventory qty again: On Hand Qty is reduces to 85 (means qty 6 has been allocated to the PO while receiving) - The flow goes in this way because the backflush is activated

 

In other words, the component is assigned / allocated to the purchase part at the point of receipt when the backflush is activated. In a scenario where you do not want to ship the component to the supplier, but you use the component part (may to pack the receiving part) at the receiving point to your warehouse, this is used.

 

If you have not activated the backflush option:

example:

 

  1. Create a PO - > Supplier Material
  1. Release PO - > try to receive the PO  → You will see below error. (means we have to manually reserve, pick and ship the qty of the component part to supplier prior receiving / purchasing the end part)

 

  1. Reserve - > Pick - > Ship supplier material
  1. Upon completion of all these steps, now the PO can be received

This is the difference when you activate / deactivate backflush.

Hope this helps

 

Thanks!

@Lakmini Weerakoon 

Hello, we’re using the backflush functionality for Supplier Material, and are manually ticking the flag below when creating the Product Structure. We would like to know if there’s a way the ‘Backflush of Purchased Components’ flag can be defaulted to ticked on the Product Structure lines when a component part is added to the Product Structure? Have checked all part settings and cannot find a flag that would affect this tick box to default to true. 

Thanks, 

Rob
