Material master data base unit

There are two types of statements on the Internet, one is to use 561 + 561 (this is also true in SAP help ), the other is to transfer to another item number 202 + 201 (it seems that this is more practical, but it may have some impact on the write-off. If it involves import and export, the Customs Department and the Customs must explain it, after all, the amount of item A disappears out of thin air, and item B is generated out of thin air)

Solution 1:

1 mm02: change material master data a and directly change the basic unit of measurement. Of course, you won't succeed at this time, but the system will remind you
For related errors, click "display errors" to list and resolve the errors one by one:
1) if there are associated requirements (dependant requirements), Plan those requirements or orders (sales orders, production
Orders, etc.) all deleted;
2) If there is a purchase order, delete the item with;
3) if a serves the BOM of a finished product, create a temporary item B with the same content and use CS20
Technical means for bulk BOM modification to complete the "B replaces a" operation;
2. If material A is an item that has been used for at least one month, mm03 displays the view "plant stock" and
Previous preriod stock in plant/storage stock is definitely worth it. If there is inventory (mmbe
). In this case, mb1c 562 is used to remove all the values of the previous month and the current month from the balance to zero, but the posting date must be
Put it on one day of last month. Remember!
3. After the above operations are completed, change the basic unit of measurement (mm02) again and save the disk after the changes are completed.
4. mb1c 561 reclaim the inventory of the previous month and the current month. At this time, it must be a new measurement unit.
5. CS20 replaces the updated a with B, and then deletes the B logic.

The problem is:
1. After the Material Unit is updated, the deleted procurement order item cannot be deleted;
2. The finance department may not allow you to "keep the current operation on the account of the previous month ".

 

Solution 2: (from Jack Wu http://blog.csdn.net/CompassButton/archive/2007/04/07/1555440.aspx)

According to the SAP prompt information, the change measurement unit must meet the following requirements: 1. This item does not have current and preliminary inventory; 2. There is no procurement application, purchase order, plan agreement for this item. However, it is far from that simple.

Based on SAP Note: 138767, the system performs the following checks when you change the unit of measure:

The base unit must not be defined as an alternative unit of measure for the material
No international article number must be assigned to the base unit
No proportion/product units must be defined for the material
No retriable material must be assigned
The material must not be used as a retriable Material
Stock must neither exist for the previous period nor for the current period
No physical inventory must be active
No reservations or dependent requirements must exist for which the deletion indicator is not set
No planned orders must exist
No purchase requisitions, purchase orders or scheduling agreements must exist for which the deletion indicator is not set
No WM transfer requirements, no WM quants or no WM posting change notices must exist
The material must not be a Bill of Material
The material must not be contained in a Bill of Material
The material must not be used as a production resource/tool
The material must not be used in task lists
No standard cost estimate must exist for the current or future period
No production orders must exist
No planned independent requirements must exist
No run schedule headers must exist
If the base unit has dimensions, no serial number profile must be assigned
No sales and distribution events ents must exist which have status not processed or partially processed.

If there is a pre-inventory, follow the sap Note: 30656 prompt, You need:

1. Post the same amount to current period stock (for example, using movement type 561) so that previous period stock and current period stock are identical.
2. Make a withdrawal posting in the previous period for the stock together with posting date (for example, using movement type 562 ).

This is a detailed step provided by sapfans (with batch management ):

1. Wait until last day of the period
2. Post GI using 201 (but I not sure why sap says used 561)
3. Period close and open new period
4. Uncheck the batch management indicator in Material
5. Reverse the GI with 202
6. Delete and archive
