MM 获取抬头条件净价

SE24
IF_PURCHASE_ORDER_MM

IM_HEADER是个接口，由系统负责实例化。
其中GET_CONDITIONS是获取抬头条件TAB页数据，可是直接通过IM_HEADER调用方法，返回的是空值。

查看方法GET_CONDITIONS，根据行号获取指定的条件定价值。全部的条目在变量po_tkomv_hash_table或tkomv中，可以尝试指针指向这两个变量。

观察行上获取条件净价的方法，标准方法通过宏命令mmpur_dynamic_cast强转my_parent，直接通过l_header调用get_tkomv获取。查看l_header方法GET_TKOMV是继承自接口IF_PURCHASING_DOCUMENT。可以用如下代码获取抬头条件净价

    DATA: lo_po_doc TYPE REF TO if_purchasing_document .
    DATA: lt_tkomv TYPE mmpur_tkomv .
    lo_po_doc ?= ir_header.
    lo_po_doc->get_tkomv( IMPORTING  ex_tkomv = lt_tkomv ) .
