当前父级为部门或岗位，无法变更为子公司!

Error message

当前父级为部门或岗位，无法变更为子公司!

What it means

verifyOrgCategory rule: a node cannot become a SUB_COMPANY (子公司) if its parent's orgCategory is DEPART or POST, because a subsidiary must sit beneath a company-level node. The parent is looked up by id and its category checked against {POST, DEPART}.

Solutions

Re-parent the node to a company-level ancestor (COMPANY or another SUB_COMPANY) first.
Alternatively, keep the node as DEPART if the parent must remain a department.
Validate the (parent category, new category) pair before saving.

Example fix

// before
sysDepart.setOrgCategory(DepartCategoryEnum.DEPART_CATEGORY_SUB_COMPANY.getValue());
sysDepartService.updateById(sysDepart); // parent is DEPART -> throws
// after
SysDepart parent = sysDepartService.getById(sysDepart.getParentId());
if (isDepartOrPost(parent)) {
    return Result.error("上级为部门/岗位, 无法变更为子公司, 请先调整上级");
}
sysDepart.setOrgCategory(DepartCategoryEnum.DEPART_CATEGORY_SUB_COMPANY.getValue());
sysDepartService.updateById(sysDepart);

Defensive patterns

Strategy: validation

Validate before calling

// Validate the (parent category, new category) pair before saving.
SysDepart parent = sysDepartService.getById(sysDepart.getParentId());
if (DepartCategoryEnum.DEPART_CATEGORY_SUB_COMPANY.getValue().equals(sysDepart.getOrgCategory())
        && parent != null
        && (DepartCategoryEnum.DEPART_CATEGORY_POST.getValue().equals(parent.getOrgCategory())
            || DepartCategoryEnum.DEPART_CATEGORY_DEPART.getValue().equals(parent.getOrgCategory()))) {
    return Result.error("上级为部门/岗位, 无法变更为子公司");
}

Type guard

public boolean parentAllowsSubCompany(SysDepart node) {
    if (!DepartCategoryEnum.DEPART_CATEGORY_SUB_COMPANY.getValue().equals(node.getOrgCategory())) return true;
    SysDepart parent = this.getById(node.getParentId());
    if (parent == null) return true;
    String pc = parent.getOrgCategory();
    return !DepartCategoryEnum.DEPART_CATEGORY_POST.getValue().equals(pc)
        && !DepartCategoryEnum.DEPART_CATEGORY_DEPART.getValue().equals(pc);
}

Try / catch

try {
    sysDepartService.updateById(sysDepart);
} catch (JeecgBootBizTipException e) {
    if (e.getMessage() != null && e.getMessage().contains("无法变更为子公司")) {
        return Result.error("请先将上级调整为公司级节点");
    }
    throw e;
}

Prevention

Validate the parent's category before allowing a SUB_COMPANY change.
Restrict drag-drop reparenting so subsidiaries cannot land under departments.
Surface hierarchy rules in the admin UI before save.

When it happens

Trigger: Setting orgCategory=SUB_COMPANY on a node whose parent (sys_depart.parent_id) is a DEPART or POST.

Common situations: Re-parenting a node incorrectly; moving a sub-company under a department via drag-drop; data import assigning wrong parent categories.
