Hi ​@ronhu You found how this works, tried the help but it still not automatically replacing the substitute part.

Thanks,

Chamath

​@Chamath Kuruppuarachchi Thank you for reaching out.

We are still not sure how to use this option. Thank you.

Hi ​@ronhu,

I do not think this functionality is working. 

In General, substituted part cannot be automatically selected due to below reasons.

· There can be lot of substituted parts for a one part and there’s no way to prioritize one from others

· The required qty of the Substitute part can be different from the original part required qty.

There was a discussion to find a technical solution for this, but it is not working in 24R2 as well. 

​@ronhu I have this working in my Apps10 UPD15 environment. As an example, I want P2 to automatically substitute for P1 when P1 is not available, so the result of an Availability Check is used.

Setup required:

• Set the flag for Allow Automatic Substitution of Parts on the Site and the Customer.
• On the Part page, set P2 as an alternate for P1.
• For Inventory Parts P1 and P2, set Availability Check = YES.
• In the Alternate Sales Parts Base Data, set P2 as the Substitute Sales Part No for Sales Part No P1. If multiple substitute parts were required you could establish a substitution Priority here.

Test:

• Set Expected LT of P1 and P2 = 5. Recall the Availability Check uses the Expected LT in its calculation.
• Remove all on-hand inventory of P1.
• Adjust available inventory of P2 = 20.
• Enter a customer order line for (5) of P1 with a Wanted Delivery Date = TOMORROW and save.
• If a Complementary Parts dialog appears, ignore it.
• Sales Part automatically changes from P1 to P2.
