Maintain Precursor Schemes for a Scheme

Use this activity to maintain precursor schemes for a scheme.

When configuring precursor schemes:

  • A scheme with a Scheme Type of Sample Preparation can only have a precursor scheme that has a Scheme Type of Sample Preparation.

  • A scheme with a Scheme Type of Analytical Preparation can only have a precursor scheme that has a Scheme Type of either Sample Preparation or Analytical Preparation.

  • A scheme with a Scheme Type of Analytical can only have a precursor scheme that has a Scheme Type of either Sample Preparation or Analytical Preparation.

  • A scheme with precursor schemes can only be a linked scheme with another scheme that has the same set of precursor schemes.

Note: This is only applicable for org-scope and lab-scope schemes; it does not apply to lab-enabled org-scope schemes. Although precursor scheme relationships can be updated (added, deleted) for enabled-scope schemes, when sample scheme records are created, the precursor scheme relationships are taken from the org-scope scheme.

Activity Steps

  1. Access the CCSCHM—Scheme application from the main menu or quick launch to display the CCSCHM—Search Scheme screen.
  2. Enter the relevant search criteria and click Search.

    Schemes that match the criteria display in the grid.

  3. Open the required scheme to display the CCSCHM—Scheme Detail screen.
  4. Select the Precursor Schemes tab.

To add a precursor scheme to the scheme:

  1. Click Lookup CCSCHM to display the CCSCHM—Search Scheme screen.
  2. Enter the relevant search criteria and click Search.

    Schemes that match the criteria display in the grid.

  3. Select the required schemes.
  4. Click Select and Return.

    The schemes are added as precursor schemes.

  5. Click Submit.

To remove a precursor scheme from the scheme:

  1. Select the schemes in the grid to be deleted.
  2. Click Submit.

    The precursor relationship is removed. This does not update existing precursor relationships between sample schemes, but effects sample schemes created after this point.
