MD01 - in what order does the MRP run pick its materials to plan


I would like to know how the MRP global run (MD01or inthe background) picks the sequence of its materials?

Is it by order of material number? first number first run? or is there anyother logic?

Thanks for any reply




The planning is done on the basis of low level code. The low-level code controls the sequence in which the material is planned in an MRP run,First the materials with low-level code 0 are planned, then the materials with low-level code 1, and so on. The lower the low-level code, the higher the number that is assigned to the material.

The level that is set in the material master record represents the level at which the material will be planned. This means that the material will only be planned once all assemblies in which it occurs have been planned and exploded.

The low-level code is set internally in the material master record when the BOM is maintained.

You can find from F1 help also.
