在SAP ABAP中，当创建或修改订单时，需要将特定信息写入抬头和工序的长文本。为了解决抬头和工序长文本无法写入或显示的问题，必须在抬头表中设置LTEXT字段为1（中文），同时在工序表中设置TXTSP = SY-LANGU。在保存操作后调用COMMIT_TEXT函数以确保文本保存。本文通过示例代码详细阐述了这一解决方案。

需求：在创建/修改订单点击保存的时候，将某些信息写入长文本中。

遇到的问题：抬头长文本无法写入/显示，工序、组件长文本无法写入/显示

解决方法：必须要在抬头表中将LTEXT字段置1（中文）

工序则需要将工序表中TXTSP = SY-LANGU

SAVE_TEXT后要COMMIT_TEXT

举例：在CO02中点击保存时将信息写入抬头长文本和第一条工序长文本
