python - SAP L_TO_CANCEL 不取消转移单

Question

我正在通过 pyrfc 和 python 使用 SAP 功能模块 L_TO_CANCEL 来取消仓库管理补货转移订单 (TO)。这适用于某些 TO，但对于其他 TO（还有补货）会给出错误 X 不允许存储类型的负库存。虽然这是真的，但 TO 还没有工作。尚未从源存储类型中移除库存。因此，取消不应导致目标存储类型出现负库存，这在这种情况下会在错误消息中指示。这是怎么回事，或者为什么我认为有问题。如果我通过 SAP GUI 从 SE37 运行 L_TO_CANCEL，传递相同的参数 I_LGNUM、I_TANUM、I_CANCL，即使 TO 与 rfc 调用相同的 TO 无法取消并且收到不允许消息的负库存，它也会取消有问题的 TO。

result = s.delete_to(lgnum="220", tanum="9592250", cancl="X", commit_work="X")

    return_msg = None
    assert (lgnum is not None and tanum is not None), "Warehouse number as lgnum and Transfer Order as tanum are required for function delete_to"
    if cancl is None:
        cancl = "X"
