Operation

Template BOMP - Production Bill of Materials must be active.

Data import

Bills of materials (BOMs) consist of a header and links.
The main table to set up is the BOM (BOM header) table. The BOM table is linked to the BOD object.
To import BOMs you must set up two identifiers, one for the header table (table BOM) and one for the link table (table BOMD).
The main object is automatically detected with the main key which is the product/route coupling.

The existence of links is acknowledged according to the following criteria:

• Search with the sequence number and the component product reference. If the line exists it is modified, otherwise it is created.
• The BOM import processes the link deletion. A link is deleted if the value for the sequence number (BOMSEQ) is negative whatever the link quantity.
  
  Examples:
• Import of a sequence 3 text line (the link quantity automatically equals 0), from the BOM:
  - To delete this line, the sequence number must be specified as a negative value (...;-3;...).
  - To create/modify this line, the sequence number must be specified as a positive value (...;3;...).
• Import of a sequence 5 line from the BOM for the component (with a null link or not):
  - To delete this line, the sequence number must be specified as a negative value (...;-5;...).
  - To create/modify this line, the sequence number must be specified as a positive value (...;5;...).
  

To import a new non-versioned Production Bill of Materials (BOM) at status 'Available to use' define a default BOM code in the BOM table field *3 (Default BOM code). The import process initially creates a non-versioned BOM as a new versioned-managed BOM at status 'In development'. When it has validated the structure of the bill is correct it then sets the new versioned BOM to status 'Available to use'.

 The default BOM code is mandatory the first time you import a versioned BOM. Subsequent imports of the same production BOM will use the default BOM code unless you select a different BOM code.

Versioned BOMs must be imported in the correct sequence.

To import versioned BOMs that are older than today's date, type 'D' in the BOM table field *4 (Option).

Data export

All BOM codes are exported.

All versions (major, major/minor) of a BOM are exported, not just the current version.

Mandatory fields in the template

Table BOM - Header BOMs

• Parent product code (ITMREF)
• BOM alternative (BOMALT)

Table BOMD - Detail BOMs (links)

• Link sequence number (BOMSEQ)
• Additional sequence number (case of options/variables).
• Component product code (CPNITMREF)
• Link quantity (LIKQTY)

Error messages

In addition to the generic error messages, the following messages can appear during the entry :

Code type incompatible

The BOM code (product + code) is already in use. You must use a different BOM code.
