The material tree is a structure tree, which you can display on the left-hand side of the MRP list and the stock/requirements list. The system includes certain materials in the material tree automatically:

• all the materials that you have selected in the material list during collective access to the MRP list or the stock/requirements list
• all the materials, for which you call up an MRP list or a stock/requirements list during a working session.

When you leave the transaction, the selection of materials is lost.

You can switch the tree between:

• worklist tree (all materials that you have processed in the respective transaction calls, or all materials that you selected in the material list)
• order tree (all assemblies or components for a selected MRP element according to the order report)
• product group tree (all materials and sub-product groups of a product group, only for access to the lists via product group)

Double-click a material in the material tree to branch directly to the corresponding MRP or stock/requirements list.
