RESB table item sequence not similar to BOM Items sequence

[Former Member]

Hi all

If we see the item sequence in MB23 display reservation or in RESB table, the sequence not matching with BOM items sequence if we compare with CS03. This problem is persisting for only the process orders created from planned orders. If I create new process order with out planned order then the sequence of the reservation items in RESB table are similar to BOM items. could you please suggest me to resolve this issue.

thanks in advance.

Is there any specific reason for this requirement?

In RESB even if the sequence is not same, you still have Item node and counter for BOM components and if you are building any ABAP logic you can use these two fields. They are from STPO table.

In my opinion, Caetano, this forum acts as a knowledge base and many people, not only the author, reach an old posting looking for some solution. That was my case, I found some update and though, wrongly perhaps, that it could be useful for somebody.

I agree many times we come across a post which sounds close to our own issue and when its doesn't shows a logical end to post or solution it disappoint the user.

@ admindsap

If answer to aged posts are not allowed, its should be auto close after certain time or if admins have option available they can close it for their respective forum.

Thanks

Even if you dont change or add components, RESB sequence number dont follow the BoM when phantom assembly are exploded.

0010 Component A

0020 PH Assembly 1 (Composed of Comp R and Comp S)

0030 Component B

The sequence in RESB table reads:

Component A

Component B

PH Assembly 1
Component R
Component S

Hi Dario

This question was open back in 2010, that means, almost 10 years ago and I bet this user does not even remember this subject anymore 🙂

I have the same problem, but I only want to know how does the system assigns the "Item Number of Reservation"?

This is an example of a Production Order and the Reservation, if you see there's is not a clear logic (all the materials have the same requeriment date).

• BOM Item Number  0010 Material A --> Item N. Reservation 001
• BOM Item Number  0020 Material A --> Item N. Reservation 004
• BOM Item Number  0030 Material A --> Item N. Reservation 002
• BOM Item Number  0040 Material B --> Item N. Reservation 003

Thanks in advance.

It cannot be random, there must be some field which is causing this, I suggest you to compare all the fields of reservation 001, 004 and 002 in RESB table in SE16N.

Hi Ray,

     I have analyzed the issue you have mentioned, the reservation field in RESB table will be updated based upon the sequence of addition of components and assigns them the sequential number. In your case may be you have inserted the second component in the change mode of production order and changed the component numbers manually. So the system has given the next reservation number. Please check and revert back.

Hi,

The item sequence in RESB follows from the order & not from the BOM. In normal cases, both will be the same if there is no manual intervention in the order or changes done.

In the case which you highlight i suspect some manual modifications were done in planned order or in the process order.

If you notice this with all planned orders, then can you just create a manual planned order (don't save) via MD11 & check in the component tabs whether you find all components in the list as per BOM

Sapproduction,

?? I don't understand why this is an issue. Perhaps I don't understand what you are saying.

Can you describe the business reasons why this is a problem?

Hi DB

Obsolutely this is an issue. The reason is while printing process order system will print based on the sequence of the items in RESB table. so the suence is very imporant to client.

SP,

I have never seen SAP state that the sequence of the BOM items will always be exactly matched by the sequence of the component items on the order.. As stated by one of the other experts, the sequence will usually follow the BOM sequence. However, if you were to open a message with OSS about this issue, I doubt you will get SAP to provide a correction (well, they won't provide one for free, anyway).

This is the first time I have ever heard of a client specifying the sequence of the items in the RESB table. I can't think of a business requirement for this, but I guess your client must have one if he is willing to pay you to make it so..... If your client has a specific sorting requirement for the items in the RESB, then I believe you will have to write some custom code to achieve this sequence. If you client only wants the printout of the items to be sorted in a way that always matches the BOM sequence, then, again, you may have to resort to custom code.
