| Procedure for linking reference designators in the BOM |  |
| In ERP LN, reference designators are linked to material on the BOM lines. You must carry out the following steps: Step 1. Define reference designators Define reference designators in the Reference Designators (tcmcs0190m000) session. The reference designators can have, for example, names or codes that indicate the locations where a component must be inserted on an item. Step 2. Link reference designators to an item. If desired, you can link reference designators to an item in the Reference Designators by Item (tcibd0120m000) session. Linking reference designators to an item manually is not mandatory, but can be useful when one or more reference designators are only applicable to a specific item. If you do not manually link reference designators to an item in this step, reference designators are linked automatically to the item in the Reference Designators by Item (tcibd0120m000) session after you carry out Step 3. Step 3. Link reference designators to material on an BOM line In the Bill of Material (tibom1110m000) session, you can link reference designators to a specific BOM line. Therefore, select the BOM line, and click Reference Designators by BOM on the menu. The Reference Designators by BOM (tibom0120m000) session now starts. Step 4. Select reference designators You must click New in the Reference Designators by BOM (tibom0120m000) session, to link reference designators. You can zoom in the Reference Designator field to the following sessions to select reference designators: If you defined reference designators by item (Step 2), you can zoom to the Reference Designators by Item (tcibd0120m000) session to select reference designators. If you did not define reference designators by item, you can zoom to the Reference Designators (tcmcs0190m000) session to select reference designators. A reference designator can apply to one or more items on the BOM line. You must use the Quantity field in the Reference Designators by BOM (tibom0120m000) session to indicate the number of items on the BOM line to which the reference designator applies. Example Suppose, the item quantity on an BOM line is six: If you enter 1 in the Quantity field in the Reference Designators by BOM (tibom0120m000) session, the reference designator applies to only one item of the quantity on the BOM line. If you enter 5, the reference designator applies to five out of six items of the BOM line quantity. You can also enter a quantity of, for example, 2 for one reference designator, and 3 for another reference designator. You can enter a quantity of 6 for a reference designator, which can mean that all items on the BOM line must be mounted on the same location. If the item quantity on a BOM line is six, you can even enter 4 as the quantity for one reference designator, and 3 as the quantity for another reference designator. This signifies that one of the items on the BOM line is related to two reference designators. Related topics Overview of reference designators Procedure for linking reference designators in the EBOM |
