我遇到了SAP ALV问题。 我想更改列的文本和颜色。 如果我直接调用列（'BONUS'）但是当我调用列时，它可以工作 在DO子句中使用它并连接它不起作用的列的名称 由于某些原因。 虽然找到了列并且属性已更改，但至少这是我在调试时看到的内容。
我希望有人可以帮助我。
以下是我的编码的一部分，应该更改属性。

我发布了这两种方法的代码。第一个是构建一个fieldcatalog并创建一个全局表，因此fieldcatalog可以在第二个方法中使用。这个应填写fieldcatalog，配置ALV（如列文本和颜色）并显示结果。

答案 0 :(得分：3)
嗯......你没有指定变量new的类型，但我认为它是STRING。如果它正在进行这样的分配
new = count.
不会删除count变量末尾的空格。
这个简单的程序显示了它。
REPORT ZZZ.
DATA: gv_row_count TYPE i VALUE 30.
DATA: fieldname TYPE char30.
DATA: new TYPE string.
START-OF-SELECTION.
new = gv_row_count.
CONCATENATE 'JAHR' new 'P' INTO fieldname.
WRITE fieldname.
输出为JAHR30 P而不是JAHR30P。
要解决此问题，您可以在CONCATENATE之后添加以下语句。
CONDENSE h_fieldname NO-GAPS.
甚至更整洁的只是使用字符串模板而不是连接，那么你就不需要变量new。
h_fieldname = |JAHR{ count }P|.

如果它适用于一个列，则没有理由不与另一个列一起使用。
照常排查代码。确保列名写得很好，并且是ALV表中现有列的名称。
