Interchangeability group - Supersession chain -Many to One , one to Many functionality in SAP APO

[former_member619700]

Hi Experts,

We have implemented product interchangeability in APO with super session chain ICG type and we are using SNP heuristics to calculate substitution order.

Our business is requesting us for below logic in Super session chain. But when adding below logic we are receiving the error"Interchangeability group is not continuous". We have also tried implementing this logic after changing the replacement type as well.

1. Many predecessor products mapped to Single successors

2.Many successors products mapped to Single predecessor.

Please advice on how to implement this logic.

Thanks,

Dharma.

Hello,

As I have explained earlier You cannot put relationships as below it will give this error.

A --> B

A --> C

The scenarios which you are looking for

1. Many predecessor products mapped to Single successors

2.Many successors products mapped to Single predecessor

works only in GATP and SPP, it do not work with SNP and PPDS.

Refer following link which explains how to maintain 1:n, n:1 and n:m relationships.

https://help.sap.com/saphelp_SCM700_ehp02/helpdata/en/12/2ec95360267614e10000000a174cb4/frameset.htm

SPRO--> APO--> Masterdata--> Product and Location Interchangeability--> Application Settings--> Maintain Interchangeability Group Types and Assign Replacement Types

You need to have 1:n, n:1 or n:m assigned to the group type something like this

then in the Super Session chain select suitable replacement type here 1:n AND (to understand whats AND and OR read the earlier link) press enter you will see an arrow appear in additional members which was X earlier. Click it and it will allow you to enter multiple successors for one predecessor

Press shift + F8 to check the applications this SSC is relevant and you would see its relevant for GATP only, not for planning.

To understand why

Read the below link which talks about restrictions of interchangeability with different applications (GATP, PPDS, SNP, CTM, DP, SSP etc)

Hi Abhishek,

Thanks for the reply. All required set is present in our system.

Still the issue persists when configuring:

1. Many predecessor products mapped to Single successors

2.Many successors products mapped to Single predecessor.

Thanks,

Hello,

In the Super session chains you need to define the relationships such that its continuous

Like

A--> B, B-->C, C-->D

you will get this message if the chain is broken

like A-->B , C-->D or A-->B, A-->C

Refer KBA

2559330 - Error " Interchangeability group is not continuous" While creating Interchangeability Group

Also if you want to use relationship like

A --> B

A --> C

This is allowed only if a rule profile exists for that relationship. The rule profile will be available only when you implement the BAdI Rule Resolution (/INCMD/RULE).
