Always run the Integrity Analysis program immediately after a data conversion, or often when BOMs are entered, changed or deleted.  It is also strongly suggested to run the Integrity Analysis program before running the Simulate Rollup (P30820) or MRP/MPS Requirements Planning (P3482/P3483) programs.  If low level codes (LLX) are out of sequence, adding new items to BOM will not produce correct costs, and MRP will not properly plan all component items.
