Closing PCRs and PCOs
Use PCR/PCO Close (1.9.14) to close or reopen any PCO that has not been assigned an effective date in Incorporation Selection (1.9.7.4). You can close PCOs that have been released and distributed but not incorporated. Close undistributed PCOs in the trailer of PCO Maintenance. You can also use this program to close PCRs that are not closed by becoming part of a PCO.
See here for details on PCO/PCR trailer fields.
Closed
If Yes, the PCR or PCO is closed. This field is reference-only, and does not establish a link to another PCO in the same way as Close PCO to PCO function in PCO Maintenance.
PCO Ref
Optionally, enter a value as a cross-reference.
Closing a PCR or PCO in this way makes a PCO available for export to another system database.
