如何在SAP中將值添加到另一個用於甘特圖的XML類別中？

Question

我正在編寫一個甘特圖，跟在this post之後，我即將準備就緒，但我遇到以下問題。

下面的代碼顯示了我用ChartDesigner設計的甘特圖，但它僅顯示了第1類中的所有框！我怎樣才能使Category2下的框（在下面的代碼中）出現在Category 2中？

APPEND '<?xml version="1.0" encoding="utf-8"?>' TO lt_data_text. 
APPEND '<ChartData> ' TO lt_data_text. 

APPEND '<Categories><Category >Category1</Category></Categories>' TO lt_data_text. 
APPEND '<Series customizing="Series1">' TO lt_data_text. 
APPEND '<Point>' TO lt_data_text. 
APPEND '<Value type="time">20000301</Value>' TO lt_data_text. 
APPEND '<Value type="time">20000305</Value>' TO lt_data_text. 
APPEND '<Value type="time">20000310</Value>' TO lt_data_text. 
APPEND '<Value type="time">20000319</Value>' TO lt_data_text. 
APPEND '</Point>' TO lt_data_text. 
APPEND '</Series>' TO lt_data_text. 


APPEND '<Categories><Category >Category2</Category></Categories>' TO lt_data_text. 
APPEND '<Series customizing="Series2" >' TO lt_data_text. 
APPEND '<Point>' TO lt_data_text. 
APPEND '<Value type="time">20000310</Value>' TO lt_data_text. 
APPEND '<Value type="time">20000315</Value>' TO lt_data_text. 
APPEND '<Value type="time">20000320</Value>' TO lt_data_text. 
APPEND '<Value type="time">20000329</Value>' TO lt_data_text. 
APPEND '</Point>' TO lt_data_text. 
APPEND '</Series>' TO lt_data_text. 

APPEND '</ChartData>' TO lt_data_text. 

Answer 1

刪除線：

APPEND '<Categories><Category >Category2</Category></Categories>' TO lt_data_text. 

變線：

APPEND '<Categories><Category>Category1</Category></Categories>' TO lt_data_text. 

到以下

APPEND '<Categories><Category>Category1</Category><Category>Category2</Category></Categories>' TO lt_data_text. 

應該工作我猜
