Interchangeability

If the part is changed to a non-interchangeable P/N, the P/N E/C Effectivity will not transfer to the new part. A warning message prompt appears stating: 'Part Numbers are not interchangeable.You must reconcile the P/N control and E/C for P/N S/N manually.'

If the P/N is changed to a non-interchangeable part, the following soft warning message appears to inform the user that the effectivity will not be transfered to the non-interchangeable part.

Follow GRB and PNSNCHG/EFFECTIVITY Configurations

When performing P/N Change transactions, it is important to take into account the following configurations that will affect P/N E/C Effectivity. See table and flow chart below.

FOLLOWGRB switch (works with Follow GRB checkbox)

When set to Yes, the Follow GRB checkbox will be available for selection via the E/C Category Transaction Code. Once selected via the Transaction Code, the Follow GRB checkbox will be available and selected by default on the Engineering Control P/N window. The system will continue to track the E/C for that GRB regardless of any changes made to any P/N S/N that is effective to the E/C including any Override schedules. This works for One Way Forward and Both Way Interchangeable P/Ns.

When set to No, the Follow GRB checkbox and the Load At Receiving checkbox will not be available on the Engineering Control P/N window. The system will not track the E/C for that GRB regardless of any changes made to any P/N S/N effective to that E/C.

Follow GRB checkbox (via P/N E/C window)(works with FOLLOWGRB switch)

When the Follow GRB checkbox is selected the system will continue to track the E/C for that GRB (Goods Received Batch) regardless of any changes made to any P/N S/N that is effective to the E/C including any Override schedules.

This checkbox functions accordingly for the following transactions:

• P/N S/N Change (Inventory Transaction)
• P/N S/N Change (Inventory Supervisor)
• P/N Receiving (Repair Orders only)
• Receiving Inspection
• P/N Modify To (via Engineering Control P/N window)
• P/N N/L/A Creation

When Engineering switch FOLLOWGRB is set to Yes, this checkbox is available in the E/C Category transaction code. This means that all P/N E/Cs for a particular E/C Category can have the Follow GRB checkbox selected (or deselected) by default.

PNSNCHG/EFFECTIVITY switch

When set to Yes, an Inventory P/N S/N Change transaction will remove the effectivity and compliance history from the old P/N S/N and apply it to the new P/N S/N.

The following table and flow chart illustrate how the two switches and checkbox work in unison.

PN_SN_CHANGE_CONTROL_AUDIT Table

There is an audit table in Trax Quick Print called 'pn_sn_change_control_audit' that shows the before and after of the data that is updated via a P/N Change transactions. This information pertains to serialized parts. The data captured includes:
   - Previous E/Cs linked to P/N S/N & Actuals
   - Previous P/N Controls and Actuals
    - New E/Cs being linked
   - New P/N Controls being linked
    - Transfer of Actuals
