On this tab the following fields can be viewed:
This tab is applied to define a Routing set and to "activate" a set as and when desired.
Initially a set cannot be added as 'active' since its specific production operations and sequence must 1st be specified. Once a set is active, it can only become inactive by activating another set.
This tab inserts and maintains the routing set "header" information to the table "PART_OPERATION_ROUTING_SET".
When the active routing set is selected, the function displays the words "ACTIVE SET" in uppercase for visibility. This is also important information since any additions or deletions of operations to/from the active set will directly impact on the status of the part operations as described in more detail below. When a routing set is activated, the planner of the part for which this has been done will be notified via an internal mail message.
This tab is applied to define the production operations applicable to a selected routing set and the data reside in the table PART_OPERATION_ROUTING_SET_LINK
The tab displays all production operations from the table Part_Operation for the selected part number (whether the operations are active or inactive) as available ops to be linked (if not yet linked to the selected routing set).
It also suggests operations that have been referenced in the Product structure as a "manufacturing deliver to operation" by auto-checking the "select" box for the user.
The user can however decide to un-check the box if the operation is not applicable at all to the new set being created.
Once the operations are copied to the set, the operations will be displayed as "Linked production operation(s)".
A routing set can only be set to "active" if the set already has linked operations.
Remember that a set only carries the linked operations and sequence. All other attributes of the operation, being setup- and run times, work centre, costed, and scheduled and others, are still defined on and derived from Part Operations.
If set A is currently active and set B is then made active, set A will automatically be set to inactive and all active operations of set B will become active in the Part_Operation table for the selected part number.
When an operation is deleted (or set to inactive) on the active set it will also auto-set the operation status to inactive on Part Operation.
In order to keep the status of part operations in line with that of the active routing set, many checks and validations were added to the Part operation triggers.
If a part has an active routing set, new production operations cannot be added as active. It must be added as inactive. Once linked to the active routing set, it will automatically become active on Part Operation.
If a part has an active routing set, the status of a production operation cannot be set to inactive if it is still active on the active routing set.
If a production operation exists on any routing set, it cannot be deleted.
Deletion of an operation from a set ONLY deletes the operation from the selected set. If the operation was on the active routing set when it was deleted from the set, it will also result in the status of the operation changing to inactive on Part Operations.
The Part Operations functionality can still be operated as always and the application of sets is an optional feature in the System.
The concept of sets can be applied to selected parts only whilst other can continue with the standard part operations. Sets can thus be applied on an "as-needed" basis.
The routing sets and links applies both the Project and Part number as part of the key. If a set for a project becomes active, it only becomes active in relation to the Project and will not influence the standard part operations.
Security for routing sets:
Users with corresponding add, change and delete-rights for Part Operations can add, update and delete the routing sets and operation links for the sets.
However, to activate a routing set, a profile with the function "part operation routing set activate" is required.
This tab contains 2 sub tabs that are applied to specify alternate production routings with linked operations and to activate a set as and when desired to become the active set of standard operations.
The routing sets have descriptive data to identify the set (e.g. 'Primary routing', 'Alternate routing #1', 'External routing') and also allows a set to be activated.
The option is thus provided where a number of routing sets can be defined for a part's production operations. The reason may be that even though a primary routing exists for a part, alternate routings that maps operations to other work centres or to external resources may also exist.
Depending on circumstances, one of these sets may be activated BUT do take note that setting a selected set to "Active", will result in an update of part operations as well. All production operations that are active for the "active" routing set will become active on Part Operation, whilst all other production operations that are not in the active set will become inactive. Other functions and procedures such as "Cost generation", "Create order operations" etc will only apply the active part operations.
A set is defined via the tab "Production routing set" and the valid operations for set is linked via the tab "Production routing set operations".
It is important to take note that if a part has an alternate routing set and the intension exists to activate it at some point, a "primary" routing set must also be created. The reason is that a set that has been activated, can only undo the activation by setting another set to active. You thus require a second set that can be re-activated when the alternate routing no longer applies.
