Business Context
An automated migration script is set up to build a specific format library for a legacy system interface. The script requests a standard list of formats to be merged from the 'LegacySource' library. However, due to data quality issues, some requested formats (e.g., '$OldGeo') may no longer exist in the source. The business requirement is that the process must NOT fail; it should migrate whatever is available so the interface can start partially.
About the Set : sessionProp
Configuration of session properties.
Discover all actions of sessionProp Data Preparation
Create a source library that deliberately misses one of the formats that will be requested.
Copied!
| 1 | PROC FORMAT casfmtlib='LegacySource'; |
| 2 | value $ExistingFmt '1'='One' '2'='Two'; |
| 3 | /* Note: $OldGeo is deliberately NOT created here */ |
| 4 | RUN; |
Étapes de réalisation
1
Attempt to merge requesting a non-existent format with ignoreNameNotFound=TRUE.
Copied!
| 1 | PROC CAS; |
| 2 | sessionProp.combineFmtLibs / |
| 3 | fmtLibsIn={"LegacySource"}, |
| 4 | fmtLibOut="InterfaceLib", |
| 5 | formatNames={"$ExistingFmt", "$OldGeo"}, |
| 6 | ignoreNameNotFound=TRUE; |
| 7 | RUN; |
2
Verify that the process did not fail despite '$OldGeo' being missing.
Copied!
| 1 | PROC CAS; |
| 2 | /* Check existence of the output library */ |
| 3 | sessionProp.listFmtLibs fmtLibName="InterfaceLib"; |
| 4 | RUN; |
Expected Result
The action returns a success status (or warning, but not a fatal error). The 'InterfaceLib' is created containing '$ExistingFmt'. The missing '$OldGeo' is ignored as requested, allowing the pipeline to continue.
