M3 351
Material not maintained in plant
ME21N or another purchasing process stops with "Material ... not maintained in plant ...".
Likely root causes
- The material has not been extended to the plant used in the document.
- The wrong plant was entered or derived for the item.
- Required plant-specific material views were never created for this material.
What to inspect
- MM03 — check whether the material can be displayed for the exact plant.
- ME21N item data — confirm the plant on the failing item.
- MM01/MM02 — verify the required plant-specific views and organizational levels.
Resolution path
- Confirm that the plant on the document is the intended plant.
- If the plant is correct, extend the material to that plant with the required views using the approved master-data process.
- Complete any mandatory plant-level data before saving.
- Retest the original document after master data is available.
