  1. A) If you do not have any stocks or purchasing document or reservations as such, you can change the material type of a material even if the material types have different account category reference respectively. But once you have some stocks, the system will not allow you to change the material type if their account category reference are not the same for the material types.

  2. B, C) Without Stocks and Purchasing Documents, changing material type has more freedom as there are less check by the system. Example, the system will allow you to proceed even the material type have different account category reference.

    For example, you can still change material type if a material has stocks provided both the material type have the same account category reference, data views, procurement choice, and similar qty and value update controls.

  3. D) Material type Qty and Value Definition will be checked once you have stocks and/or purchasing documents for the material concerned. And the condition is in this case the definitions in both material types must be the same. However, as said in previous node, if no stocks and/or purchasing document do not exist for the material. Still, the system may be issuing a warning message.

    For example, a material was created with material type UNBW, no stocks currently, you have decided to change it to ROH; the change is possible but you may find a message asking you to check the material because in UNBW the purchasing group is optional but ROH the purchasing group is mandatory.

  4. E) Again without stocks less check by system and with stocks more check by the system. But if the material types have the same data view definition, the material type change is easier. It becomes a problem when you have a material type with external procurement possible plus purchasing view and the target material type was set with external procurement not allowed and no purchasing view selection. In general, it tends to complicate the checking and result in erroneous scenarios.

  5. This question seems easy but it presents with many complicated combinations of system check depending on the current condition of the material concerned. Sometimes, system respond is not as direct and the documentation from SAP may not be 'that clear' that describes all possible combination scenarios for the changes to occur. So, read carefully the question and answer and deal with it accordingly and hopefully the language presentation in the exam is clear as well.
