Background documentation Displaying the Entire Drawing for an Assembly  Locate the document in its SAP Library structure

The system displays the entire assembly in the viewer when you activate the check - box for an assembly in the object browser.

A complete drawing for an assembly is best case scenario for performance issues. You can especially improve performance with assemblies that have many components when you assign a complete drawing (assembly file) to the header of the assembly.

The following explains why:

When you display an assembly the system checks whether a complete drawing (assembly file) exists for the whole assembly. The complete drawing must be assigned either to the header of the assembly or to the appropriate BOM items.

When however no complete assembly exists the system loads all documents that have items of the assembly assigned to them (part files) and builds the drawing using the assigned transformation matrices.

Example

The BOM for Turbine T-20000 has items T-20100 (turbine casing) and P-100 (pump). The pump P-100 is an assembly that has items 100-100 (coil housing) and 100-200 (impeller).

Turbine T-20000

This graphic is explained in the accompanying text

When you display Turbine T-20000 the system checks whether the BOM item for the pump P-100 (blue in the graphic) is assigned to a complete drawing.

If this is not the case the system checks whether the BOM header for the pump P-100 (red in the graphic) is assigned to a complete drawing for the pump.

If this also is not the case the system loads drawings for all items of the pump; 100-100 and 100-200, and displays them in the viewer.
