732027是一个由数字组成的代码，但没有提供上下文来解释为什么申购不了。因此，本文将根据关键词为基础进行一些猜测和探讨。

首先，我们需要确定732027所代表的是什么。如果它是某种产品或服务的代码，那么无法申购可能有几个原因。可能是该产品或服务已下线或暂停销售，也可能是申购时间已截止，或者您没有符合条件的资格申请。

如果732027代表某种证券代码，比如股票或债券，那么无法申购可能是因为该证券目前不可交易。这可能是因为市场关闭、证券停牌或其他市场限制。

另外，如果732027是一个错误的代码或输入错误，也会导致无法申购。在这种情况下，您可以尝试纠正代码或重新输入正确的信息。

最后，如果732027是一个虚构的代码或代表一个不存在的事物，那么无法申购是理所当然的结果。在这种情况下，您需要确保提供准确的信息和正确的代码。

总之，无法申购732027可能是由于产品或服务已下线、申购时间已截止、市场限制或输入错误等原因。如果您确定代码和相关信息的准确性，并且仍然无法申购，建议与相关机构或客户服务部门联系以获取进一步帮助。
