In this setup, a part with one or more AVLs with an AVL Material Type (AMT) of Lead-PB will not assign Lead-PB to the Inventory Material Type (IMT). However, in this case, if a part has any combination of the LF or RoHS in the AVLs, it can be assigned UNK at the IMT level. A part could also assume the RoHS or LF if they were set up the same way.

Logic Terminology

"ALL" means that every AVL for a part has the same material type. There can only be one "ALL" AMT selected for an Inventory Material Type. The rest of the AVL material type conditions are not relevant. 

"INC" means that any AVL Material Type in this category may be included in the Inventory Material Type. 

"NOT" means that none of the AVLs can contain the AVL Material Type to qualify for the Inventory Material Type.

Let’s take the first IMT, LF,  as an example, and say that any of the LF* AMTs can also be called "LF." Additionally, the RoHS* AMTs can be included, because they are also lead-free. But there cannot be "UNK" or "LEAD."

Now consider the IMT RoHS. This designation may not include the LF, as the RoHS involves a tighter control on the materials. So only the RoHS AMTs can be included.

Considering the UNK IMT, this condition basically says that if any AMTs include UNK, then the IMT is also "UNK." 

And finally, of the Pb category for IMT, the assumption is that if all AVLs have the AMT designation of "LEAD," then the IMT should be called "Pb."

If the user wishes to go further in the definitions, perhaps the IMT called "MIXED" would be a preference to distinguish that both LF* and RoHS* are in the AVLs. 

Both the LF and MIXED IMT would have the same conditions. In that case, one or the other would be unnecessary, or would need to be modified, for instance by making LF inclusive of only LF*.

In this situation, parts with the LF AMT could be considered as either MIXED or LF, since the setup does not specifically exclude RoHS.

To address this situation, the user is allowed to establish the order in which the logic is checked. This means that the IMT setup can be sorted in order of priority.

The logic would check for the LF condition first. It would then be the first logic choice for both the conditions E and F above.

To differentiate better between E and F, the priority order may be modified to place MIXED as the higher priority. It would then assign "MIXED" as the first logic choice for both the conditions above.
