In addition to having the ability to create new TMP parts, the CIP Distributor Search also allows you to add distributor and manufacturer data to an existing TMP or formal part. You also have the option to update part data when adding to an existing part. Updating part data overwrites your changes as well. To add multiple distributor parts, you will need to open the component page.
The Add to Existing Part feature allows (specified) users to:
•Add New Manufacturer Parts, including Distributor Data (Dist. PN, Cost, Quantity), to Existing TMP or Formal Parts
•Update/Overwrite Distributor Data (Dist. PN, Cost, Quantity) of a Manufacturer Part that is associated with an Existing TMP or Formal Part
•Update/Overwrite Distributor Data (Dist. PN, Cost, Quantity) and Common Manufacturer Data (Datasheet, RoHS Compliant, Image) of a Manufacturer Part that is associated with an Existing TMP or Formal Part
•Update/Overwrite Part Data
