Unable to locate sequential file handlers for files TRANREPT in CBTRN03C program context

This error is related to the transaction report generation in the AWS Blu Age L3 Workshop. The issue "Unable to locate sequential file handlers for files TRANREPT in CBTRN03C program context" typically occurs when there's a problem with the file configuration or the Groovy script execution.

Based on similar issues in the L3 Workshop, here are some potential solutions:

1. Check your TRANREPT Groovy script for missing property definitions. A common issue is the "MissingPropertyException" for variables like "programResults" or "fcmap". You may need to add:

Map programResults = [:]

to your script before it's used.

2. Verify the file configurations in your TRANREPT script, particularly for the TRANREPT file in the STEP10R section. Make sure the file paths, dispositions, and record sizes are correctly defined.

3. If you're using the INCLUDE COND in your script for date filtering, there might be issues with how dates are being compared. Some workshop participants have found that changing from ZD (zoned decimal) to CH (character) format and modifying or removing the INCLUDE COND can help resolve issues.

4. Check if all required files (TRANSACT.BKUP, TRANSACT.DALY, and TRANREPT) are being properly created in your working directory. If not, the sequential file handler error might be occurring because the prerequisite files don't exist.

5. If you're working in the AWS Mainframe Modernization environment with BluAge 4.2.0, there might be environment-specific issues that differ from the AppStream environment. In particular, check for missing programs like CEEDAYS that might be required for date processing.

By addressing these potential issues, you should be able to resolve the sequential file handler error and successfully generate the transaction report.
