A BOM is not exploded in the following situations:

- No BOM is effective:
-- On the explosion date and in the given area of validity
For the given effectivity parameters

- The BOM has a deletion indicator.

- The BOM is a multiple BOM, and has no alternative that matches the lot size for your required quantity.

- No BOM matches the selection criteria of the BOM application you selected.

- This is possible in the following situations, for example:

-- The application does not take all BOM usages into account.
For example, the application only takes BOMs that are relevant to production into account, so a BOM that is relevant to sales and distribution is not exploded.

-- The application selects a specific alternative on the explosion date you require. The material master record supports alternative determination by Explosion date.
If the specified alternative is not valid on the explosion date, the BOM is not exploded.

-- The application takes production versions in the material master record into account, but no production version has a BOM that is valid on the explosion date you require. The material master record supports alternative determination by Production version.Advertisement

The system only explodes the BOM defined for the production version that matches the alternative and/or usage entered on the explosion date required.

-- The application only takes BOMs with certain status indicators into account.
For example, the application for MRP only explodes BOMs that have at least the status Explosion for MRP.

Further checks:
- Do the proper Scheduling in Routing (Backward/forward). In md61 give the requirement in next month.check your in-house production, planned delivery time in md02 give MRP Control parameter Rexplode BOM and Routing.

- Check BOM explosion data in MRP4 view of material master view ( Individual/Coll data).
