Substitution fails...in RBA

Hello,

I am running into a problem in Rule Based ATP.

In our Check instructions for Rule based ATP Check, I have selected 'Create Remaining Requirement for Source Location product'. My assumption was this:

1. Material A Req Qty 200

2. Material A Stock 100

3. Material B Stock 50(We can substitute this for Material A)

4. With the above setting I thought I would be able to create a planned order for Material A(we have CTP running) for 50. Unfortunately the system ignores Material B completely and creates a Planned order for Material A for 100. Flabbergasted.

If this is how it is going to work, then there will never be a substitution. Am I missing something?

Thanks in advance,

Subash Nanjangud

    Hi Subash,

    It seems like CPT functionality is getting triggered before RBA rules.

    Please check the following configuration in the Check instructions.

    Production time setting should be - After executing all check methods

    Hi Mohit,

    Apologies for Monitor(thanks to ipad auto correct). This is the setting I already have but not working.

    What else can we try?

    Thx,

    Subash

      Hi,

      You can try the setting in Check instruction to enable Immediate RBA rule. That will make sure RBA rule is triggered immediately before CPT.

    Thanks Mohit...I will try that. What release are you on? My screenshot above looks different from yours but the same functionality.
