Hello,
When trying to change material type from HAWA to WERT i got the message.
The material type cannot be changed.
The reasons for this are:
The old and new material types have different material type IDs.
ID of new material type:
No material type ID
ID of old material type:
Value-only material
Could you please if it can be change and how?
Regards
M

You can change it in tcode MMAM. However, you can only change it it hasn't been used previously anywhere.

Hi,
Material Type can be changed using t.code: MMAM but the check following prerequisites:
Configuration of both material types must be similar {quantity & value updates in t.code:OMS2 - Material Type configuration with screen views}
There should be no open purchase order or production order against material
There should be no valuated stock against material
There should be no open line items against vendors for material (Just cross check with t.code:FBL1N - Vendor Line Item display}
More check link:

you can only change material types which have the same material type ID
see table T0134 field WMAKG
Your HAWA material type has a blank in that field while WERT has a 1 in there.
It is a hard coded error.
you have to create a new material and set a deletion indicator to the old one.
