要將增強(qiáng)字段一并append到如下四個(gè)表/結(jié)構(gòu)中：

如果增強(qiáng)字段在銷售訂單抬頭(vbak)上

• VBAKKOZ
• VBAKKOZX
• BAPE_VBAK
• BAPE_VBAKX

在行項(xiàng)目(vbap)上：

• VBAPKOZ
• VBAPKOZX
• BAPE_VBAP
• BAPE_VBAPX

在運(yùn)貨計(jì)劃行(VBEP)上：

• VBEPKOZ
• BEPKOZX
• BAPE_VBEP
• BAPE_VBEPX

11-08今天做了一個(gè)測(cè)試，實(shí)際操作了一下append進(jìn)去ABAP中，然后通過(guò)BAPI去修改字段

TABLE VBAP

vbap append構(gòu)造

STR BVPE_VBAP

BVPE_VBAP append構(gòu)造

STR BVPE_VBAPX

BVPE_VBAPX append構(gòu)造

STR VBAPKOZ

VBAPKOZ append構(gòu)造

STR VBAPKOZX

VBAPKOZX append構(gòu)造

代碼如下

這次還遇到了一個(gè)非常有意思的問(wèn)題。剛開始沒辦法修改成功（return的東message都是成功），最后通過(guò)查找資料發(fā)現(xiàn)，構(gòu)造VBAPKOZX的類型必須使用char1去定義，如果和其他一樣用char，長(zhǎng)度1，沒法識(shí)別。
