System-level programs are the connecting tissue with application programs using object types. These object types are used by CMiC API's to exchange data between system-level objects like attachments or user-defined extensions, setup within the application level object. For example, the project object type PMPROJ is used to upload files to the the attachments object document folder assigned to a project. Below are supported Object Types. | Application | Object Type | Description | | --- | --- | --- | | Project Management | CMOWNCO | Owner Change Order | | Project Management | DMISSUE | Issue | | Project Management | PMADDEND | Addendum | | Project Management | PMCHK:TYPE1 | Weekly Check List | | Project Management | PMCHK:TYPE2 | Monthly Check List | | Project Management | PMCHKLST | Check List | | Project Management | PMCMN | Communication | | Project Management | PMDAYJR | Daily Journals | | Project Management | PMNOTICE | Notice | | Project Management | PMPL | Punch List | | Project Management | PMPROJ | Project | | Project Management | PMRFI | RFI | | Project Management | PMSBM | Submittal | | Project Management | PMTRNSMT | Transmittal | | Project Management | PREQUALUDF | Prequalification UDF Tab | | Project Controls | DMWO | Work Order | | Project Controls | DMWI | Work Item | | Project Controls | FCASTUDF | Forecast UDF Tab | | Project Controls | SCCO | Subcontract Change Order | | Project Controls | SCMAST | Subcontract | | Human Capital Management | HRJOBCLASS | HR Job Classification | | Human Capital Management | HRPOSITION | HR Positions | | Human Capital Management | PYEMPLOYEE | Employee Profile | | Opportunity Management | OMOPPO | Opportunity | | Opportunity Management | OMOPPOUDF | Opportunity UDF Tab | | Opportunity Management | OMORG | Organization | | Opportunity Management | OMSALESBDG | OM Sales Budget | | Core System | SYSAI | Action Item | | Core System | SYSCONTACT | System Contact |
