RCM-DZ v1 — unbalanced

Publication blocked — simulation produced unbalanced entries (CFG-05 acceptance) Draft VAT code RCM-DZ v1 “Reverse charge — designated zone” failed golden example GC-VAT-014: simulated journal Dr AED 105,000.00 / Cr AED 104,750.00 — out of balance by AED 250.00. Failing account mapping: tax group RCM-DZ has no credit mapping to 23115 — VAT Output · Reverse charge. The version returned to Draft; fix the mapping in the posting profile and re-validate. Evidence retained on the version record.
