Hi,

I’m running the CUPS (CUMA) command in CATIA, and I’m trying to avoid creating manufacturing assemblies for fake items in the BOM tree.

I’m working within the DELMA_AssignableProductValidation Business Logic (BL), which runs before DEMLIA_GetMfgItemReferenceToUse. I can successfully detect fake items by checking the instance attribute V_InEBOMUser.

if (ThisInstance <> NULL and ThisInstance->HasAttribute("V_InEBOMUser"))
    if(ThisInstance->GetAttributeBoolean("V_InEBOMUser") == false)
        isFake = true // return validation false

However, the problem is that child items under these fake items have regular instance relations and do not carry the V_InEBOMUser attribute. As a result, they are not detected as fake, and their MBOM entries are still created—which I want to avoid.

EBOM

prd1
 |-prdsub2
    |-prdsubsub1
 |-prdFAKE1     ---> Should not be created 
    |prdFAKESUB1--->  Should not be created

MBOM

mass1
 |-masssub2
    |-masssubsub1
 |-massFAKESUB1 --> this should not be created yet created.

Is there a recommended way to identify and block MBOM creation for these children of fake items? Should I handle this logic in a different BL or is there a better approach to propagate the fake status down the tree?

Thanks in advance!
