Change the base unit of measure (change the measurement unit)

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
