环境:SAP CRM WebClient UI
需求:在WebClient UI里不通过用户手动点击,而是使用JavaScript代码自动触发ABAP后台的代码。
解决方案:
1. 定义一个hidden button, 其onClick事件处理函数(event handler)设置成SAP ABAP后台的event Refresh:
2. 通过document.getElementByID拿到该button的实例,再调用其方法click()触发ABAP backend事件:
var button = document.getElementByID("<%= button_id %>"); button.click();
打开page,发现backend event成功被触发:
BAP 7.40推出了许多新的关键字 - keyword,您的Sublime Text可能无法针对这些新关键字实现期望的语法高亮显示(syntax highlight)或者自动完成(auto completion)。
实际上只需手动修改Sublime Text安装目录下的DataPackagesABAP里的两个文件就能保证对于SAP ABAP Netweaver新推出的关键字,也能支持语法高亮显示和自动完成:
1. ABAP.tmLanguage
例如增加对REDUCE关键字的支持:
2. ABAP.sublime-completions
将期望支持自动完成功能的关键字维护进这个文件的对应位置即可。
测试:REDUCE这个新关键字能够自动完成,输入完成之后呈自动高亮状态。
我在S/4HANA的事务码MM02里为Material维护图片文件作为附件:
通过如下简单的ABAP代码即可将图片文件的二进制内容读取出来:
REPORT zgos_api. DATA ls_appl_object TYPE gos_s_obj. DATA lo_gos_api TYPE REF TO cl_gos_api. DATA lt_attachment_list TYPE gos_t_atta. DATA lt_role_filter TYPE gos_t_rol. DATA: lv_id TYPE matnr VALUE '16', lt_att TYPE TABLE OF sibflporb. CALL FUNCTION 'CONVERSION_EXIT_MATN1_INPUT' EXPORTING input = lv_id IMPORTING output = lv_id. ls_appl_object-typeid = 'BUS1001006'. ls_appl_object-instid = lv_id. ls_appl_object-catid = 'BO'. START-OF-SELECTION. TRY. lo_gos_api = cl_gos_api=>create_instance( ls_appl_object ). APPEND cl_gos_api=>c_attachment TO lt_role_filter. lt_attachment_list = lo_gos_api->get_atta_list( lt_role_filter ). CATCH cx_gos_api INTO DATA(error). WRITE:/ error->get_text( ). RETURN. ENDTRY. DATA: ls_key TYPE gos_s_attkey, lv_base64 type string. LOOP AT lt_attachment_list ASSIGNING FIELD-SYMBOL(
然后我把这段代码封装到一个Function moduleZDIS_GET_MATERIAL_IMAGES里,在Java代码里消费这个function module,把S/4HANA返回的二进制内容存成本地图片文件。在ABAP系统里图片二进制文件内容的类型为RAWSTRING,如何在Java里使用它?
使用JCO在Java里消费ABAP function module的代码:
static private void getProductImageTest(){ JCoDestination destination = null; try { destination = JCoDestinationManager.getDestination(DESTINATION_NAME); JCoRepository repo = destination.getRepository(); JCoFunction stfcConnection = repo.getFunction("ZDIS_GET_MATERIAL_IMAGES"); JCoParameterList imports = stfcConnection.getImportParameterList(); String materialID = "16"; imports.setValue("IV_MATERIAL_ID", materialID); stfcConnection.execute(destination); JCoParameterList exports = stfcConnection.getExportParameterList(); int abapDuration = exports.getInt("EV_DURATION"); StringBuilder sb = new StringBuilder(); sb.append("{ \"" + ABAP_DURATION + "\": " + abapDuration + ","); sb.append("\"" + UPSELL_PRODUCT + "\":["); JCoTable codes = exports.getTable("ET_IMAGES"); int row = codes.getNumRows(); System.out.println("Total rows: " + row); System.out.println("ABAP duration: " + abapDuration); for( int i = 0; i < row; i++){ codes.setRow(i); sb.append("{\"" + FILE_ID + "\":" + codes.getString("FILEID") + "," + "\"" + FILE_OWNER + "\":\"" + codes.getString("OWNER") + "\"" + ","); sb.append("{\"" + FILE_CDATE + "\":" + codes.getString("CREATION_DATE") + "," + "\"" + FILE_NAME + "\":\"" + codes.getString("FILENAME") + "\""); storeLocalFile(codes); if( i < row - 1){ sb.append("},"); } else{ sb.append("}"); } } sb.append("]}"); System.out.println("Final json: " + sb.toString()); } catch (JCoException e) { // TODO Auto-generated catch block e.printStackTrace(); } }
其中把ABAP的类型为RAWSTRING的字段保存成本地文件的代码封装于方法storeLocalFile里:
static private void storeLocalFile(JCoTable codes){ InputStream is = codes.getBinaryStream("FILECONTENT"); try { File file = new File("c:\\temp\\" + codes.getString("FILENAME")); byte[] bytes = new byte[is.available()]; is.read(bytes); OutputStream output = new FileOutputStream(file); BufferedOutputStream bufferedOutput = new BufferedOutputStream(output); bufferedOutput.write(bytes); bufferedOutput.close(); is.close(); } catch (IOException e) { e.printStackTrace(); } }
执行Java代码后,在本地C盘temp目录下能够看到S/4HANA里Material ID为16的两个附件图片:
