I check the unclear documents as follows:

1. Check your settings for program SAPF124 in transaction OB74

2. When executing program SAPF124, tick the "GR/IR account special process" flag and select "Detailed list with error
    log"when running SAPF124. Review the log to see why the GRIRs are not clearing

3. Run transaction MR11 in "Prepare list" mode to see why the GR IR's are not clearing.
