"Recursive" or "Recursive allowed" issue when actually BOM not recursive !!

[jeffrey_pepito]

Dear Experts,

Greetings !!

Issue:

Our client has some BOMs for which "Recursive" or "Recursivness allowed" is checked for some components. But when we drilled down the BOM manually (including Alt BOMs) till last level, we didn't see any materials got repeated or used again.

But still when we tried to uncheck and save, it says "BOM is recursive". But when we delete (not deletion flag) the whole BOM and recreate again the check is gone. And now BOM explodes in CS11/CS12.

My queries:

1. Why it is not allowing to uncheck the check box directly, but then disappears after BOM deletion and recreation??

2. And in some worst cases, it is not getting unchecked even after complete BOM deletion, when actually it's not a recursive BOM at all.

We're really confused, request experts to kindly help on the same !!

Thanks in advance !!

Jeffrey

Hi,

You can TRACE the recursive BOM using the SAP OSS note and then determine the components accordingly

839879 - Trace 'BOM is recursive'

You can also check the details of a similar query in the below link

Thanks.

Hello Jeffrey,

Did you check at table(STPO) level whether that same component is available with change number ? If yes, there are some threads available on forum with 'Bom recursiveness and ECM' . Please check, that might help you.

This is one Such Example>>> Recursion happened, because, one of the BOM Component, which is Assembly ( This assembly contains, Header Material is sued as one of the Coponent)
Hope this example helps. Thanks & Regards : Raja

Hi Jeffrey

Thanks for the quick reply, Sorry for the delayed reply.
Based on the Inputs shared. it looks , below situation might be the case, causing as the Recursive BOM
BOM >>> Header Material >>>100000043166
One of the BOM Component >> 100000001495
This BOM Component is the Assembly>> This Assembly might be used the BOM Header as one of its one Component.
In this case also, System will rise the BOM is Recursive Error

Hi
Did anyone got the answer for this query or situation

[abhishek_sarkar10]

Is this material - 100000001495 assigned as Phantom assembly in the BOM...?

[jeffrey_pepito]

Hi abhishek, no its not a phantom assembly.

Hi Jeffrey
Based on the Info shared in the above

As you know well, in the BOM, we the situation of "Recursive", occurs only, When the BOM Header is used as one of the component. (This will not arise, by using the same component for more than one time). This is just for your Info. Hope you too ware of it.
>>>For further analysis of the reported issue, could you please share the Item List Screen shot along with Header, to understand the root cause of the reported case. Thanks for your kind co-operation. Thanks & Regards : Raja

Dear Reddy,

With regards to your reply, as shown below, 100000001495 material is not used anywhere in its Sub-assembly, neither in other sub assemblies of this BOM as well.

But still system throws error, when we tried to uncheck "Recursiveness allowed" check box,

Hope its clear now !!

Regards,

Jeffrey
