SAP里常常要画各种smartform，并且用户还希望保存至本地PDF文件，下面就详细说明smartform转成PDF的四种方法，如果还有其他方法欢迎留言补充。
一、代码开发
1）先调用smartform函数获取OTF格式数据
2）后调用函数CONVERT_OTF转换成PDF格式数据
3）再调用GUI_DOWNLOAD函数下载
示例代码如下（本示例中需下载四个smartform对应的四个PDF文件）
METHOD DOWNLOAD_PDF.
DATA: LT_FORMNAME TYPE STANDARD TABLE OF /PICM/ADOBEFORM_STR,
LT_OTF TYPE STANDARD TABLE OF ITCOO,
LT_LINES TYPE STANDARD TABLE OF TLINE,
LT_DATA TYPE STANDARD TABLE OF ZSSD042,
LS_DATA TYPE ZSSD042,
LS_CONTROL_PARAMETERS TYPE SSFCTRLOP,
LS_OUTPUT_OPTIONS TYPE SSFCOMPOP,
LS_JOB_OUTPUT_INFO TYPE SSFCRESCL,
LV_FILENAME TYPE STRING,
LV_PATH TYPE STRING.
DATA(LV_TIME) = SY-DATUM && SY-UZEIT.
DATA(LT_VBELN) = T_ALV[].
DELETE LT_VBELN WHERE CHOOSE IS INITIAL.
SORT LT_VBELN BY VBELN.
DELETE ADJACENT DUPLICATES FROM LT_VBELN COMPARING VBELN.
IF LT_VBELN[] IS INITIAL.

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
IF LV_PATH IS INITIAL.
RETURN.
ENDIF.

ENDMETHOD.二、?通过打印池假脱机请求转成PDF文件
1）打印smartform输出假脱机请求
2）SP01查看假脱机请求，选择菜单中 假脱机请求->转发->导出为PDF 进行下载，或者执行SAP标准程序RSTXPDFT4输入假脱机请求号进行下载
?执行程序RSTXPDFT4
三、在打印预览界面输入Tcode PDF!预览PDF，点击保存按钮进行下载
四、使用PDF虚拟打印机，本电脑使用的是微软自带的Microsoft?Print?to PDF虚拟打印机
SPAD配置输出设备
1）如果?主机假脱机访问方法?选择了 G：使用控制技术的前台打印，则先设置smartform打印选项后选择打印机
?打印smartform
?选择打印机
?2）如果?主机假脱机访问方法?选择了 F：计算机前台打印，则设置smartform打印选项时可同时选择打印机
?设置smartform打印选项并选择打印机
