 <note important>Since version **9.7.5** is recalculation of evicted attribute **not starts on save a attribute** (SysRoleSystemAttribute)! Attribute on the system is **marked as evicted only**. Recalculation will be processed during first using of controlled values. This is typically on first **update provisioning**. **Beware** if new account is created and create provisioning is executed, then recalculation is not executed, because in this situation are controlled values not needed!</note>
+<note important>The merge attribute value must be a **constant**. For performance reasons, all system merge values are cached and this cache is recalculated only if the corresponding **role attribute changes**! **If the value is dynamic, the cache will not contain the correct data!**</note>
