MMAM is just technically.

Think about your number range, and execute MMAM only if the number range of both material types are equal, other wise you screw up your number range logic.

Hi,

Use t.code: MMAM - for changing the material type but you change the material type in MMAM transaction automatically also the valuation class will be changed in material master. The system will take the changed material type valuation class which was created for that material type.

If valuation class changed, U have to take care of..

1) Valuated stocks in the current period or in the previous period.

2) Open purchase orders may be there.

3) Production orders which a goods movement has already taken place.

For this first you have to do the following:

If valuated stocks already exist, you can change the valuation class only:

1) Post the stocks of the material to an interim account.

2) Change the valuation class in the material master record.

3) Post the stocks of the material back to their original account.

If open purchase orders already exist, you can only change the valuation class if you first flag the corresponding purchase order items for deletion.

If production orders exist for which a goods movement has already taken place, you can only change the valuation class if you first set the status of the production orders to deleted
