MMBE output problem

[Former Member]

Hi ,

When we are reserving materials through maintenance order (IW31),

we can see the reserved quantity through MMBE.

but the unrestricted quantity remains the same and does not reduce.

This is not correct. If we are reserving a material in the maintenance

order, then its unrestricted quantity should reduce and the reserved

quantity should increase.

This is not happening in our current scenario.

For e.g

if there is a material A and it has unrestricted quantity as 2.

If i reserve 1 quantity through maintenance order.

Then its unrestricted quantity should reduce to 1 and reserved quantity should increase to 1.

but when we view the MMBE transaction, it shows quantity 2 in unrestricted and 1 in reserved.

Shouldn't the unrestricted quantity reduce to 1??

Please advise.

Is this a duplicate post? There is an exactly same question by another user

Anyways I have copied the the answer posted to that question.

SAP behaves properly.

Reservation is a kind of requirement and has no impact on stock level at all. It just resrves stock as its name indicates.

E.g.

stock level: 10 pcs

reservation qty: 8 pcs

available stock = stock level - reservation qty = 10 pcs - 8 pcs = 2 pcs

You can check the available stock level in MD04, you can also check avalabilty in CO09.

So, please understand that "unrestricted stock" is the stock level and it represents the stock that you have physically. Available stock is the virtual stock level when you consider requirements and reduces the physical stock level by them to know how much goods you have that will not be consumed by requirements..

So,stock level and available stock level are different categories. Check MD04, examine the report and you will understand how it works.

++++++++++++

Reservation will not be reduce the unresticted stock.

see the SAP help

What are the Results of a Reservation?

When a reservation is entered, the following events occur in the system:

The system creates a reservation document, which serves as proof of the request.

In the material master record, total stock and unrestricted-use stock of the material remain unchanged. Reserved stock is increased by the reserved quantity. In MRP, available stock is reduced by the reserved quantity. This is visible in the current stock/requirements list. The reservation causes an entry to be made in the requirements planning file.

hi,

No it'll be under the unrestricted use only...because you are making the maintainence order not reservations....
