| DUPLIC! | Components in staging and baseline libraries are identical. | 
| SYNCH0! | Package Master contains no record of this component. | 
| SYNCH1! | Non-load component has no ISPF statistics. | 
| SYNCH2! | Like-source component was compiled without using the designated compile procedure and options. | 
| SYNCH3! | IDRDATA in a load component cannot be read. | 
| SYNCH4! | Like-copy component in a staging library was changed more recently than the calling likesource component in a staging library in the same package. | 
| SYNCH5! | Like-copy component in a staging library was altered more recently than the calling like-source component in the baseline library. | 
| SYNCH6! | Component in a staging library has no corresponding Component Activity File member in the package. | 
| SYNCH7! | Statically linked called load in a staging library was changed more recently than the calling load component in a staging library in the same package. | 
| SYNCH8! | Statically linked called load in a staging library was changed more recently than the calling load component in the baseline library. | 
| SYNCH9! | Load component in a staging library does not match the corresponding like-source component in the package. | 
| SYNCH10! | Component in the baseline library has changed since the component was checked out to a package staging library. | 
| SYNCH11! | Component in a staging library was changed without using ChangeMan ZMF. | 
| SYNCH12! | Component was copied into a staging library without using ChangeMan ZMF, or it is left over from a stage job that abended. | 
| SYNCH13! | Component in the baseline library was changed more recently than the component in a staging library. | 
| SYNCH14! | Package component is not in Active status. | 
| SYNCH15! | More recent version of like-copy or LCT component resides in a staging, promotion, or baseline library than was used to stage a likesource component in a package. | 
| SYNCH16! | Like-copy component in the package, which doesn’t contain the calling like-source, was changed after the baseline version of the likecopy but before the calling like-source in baseline. | 
| SYNCH17! | Like-copy component in a staging library was deleted after it was used to stage or recompile a like-source in the package. | 
| SYNCH18! | Called load in a staging library was deleted after it was statically linked into a composite load in the package. | 
| SYNCH19! | A package master record points to a package component that is not in the staging library. | 
| SYNCH20! | Statically linked called load in staging library has timestamp (SETSSI) that does not match the timestamp expected by audit. | 
| SYNCH21! | Remove either the scratch/rename request or the component it refers to from the relevant package. | 
| SYNCH22! | The sub-component to be scratched is in use by the indicated top-level component. Remove the reference to the sub-component or remove the scratch request. | 
| SYNCH23! | The sub-component to be renamed is in use by the indicated top-level component. It may not be possible to resolve this until after the rename has been processed in baseline. Change the reference to the sub-component or remove the rename request. |
