Support for JMHZ in ABRA Flexi was developed based on information available from the ČSSZ (Czech Social Security Administration) and the MPSV (Ministry of Labour and Social Affairs).
Since the JMHZ specifications and methodology were provided gradually, often with delays, and in some cases not entirely unambiguously, it was not possible for us to cover all scenarios with 100% accuracy already in the first version.
We have been working on the implementation continuously and will keep iteratively refining and expanding it based on newly available information and feedback from real-world use.
🔧 Ongoing fixes and updates
Released versions gradually include fixes and behavior refinements based on:
clarifications of the methodology by the ČSSZ / MPSV
real data and situations reported by customers
identified inconsistencies in report submission
Individual fixes will always be described in more detail in the changelog.
