SAP MIRO 基础信息抬头文本传输到行项目文本增强text transfer to accounting document

现象：

1.SAP MIRO在进行发票过账的时候，行项目是通过采购订单带过来的数据，在维护好相关的信息点击保存之后过账发现，抬头-》基本信息-》文本中的数据并没有带到生成的2张凭证行项目文本中，只有原始凭证有文本数据，后继凭证没有文本数据。

2.如果是在MIRO行项目中的某个采购订单行里面写入文本后进行过账，发现原始凭证和后继凭证就又都有相同的文本了，但是用户一般只维护抬头文本，所以有这个增强需求。

处理过程：

1.通过查阅官方note 837859发现需要CMOD中对LMR1M004进行增强，写入E_SGTXT = TAB_DRSEG-SGTXT，但是debug的时候发现，实际上即使是有抬头文本，但是实际上TAB_DRSEG-SGTXT的字段是空值，这个exit  EXIT_SAPLMRMP_004的传参只有        E_SGTXT、TAB_DRSEG，没有抬头的参数，所以没办法直接处理。

2.通过查阅官方note 366412 发现，实际上这个是标准的一个“bug”，需要打补丁进行修复，但是因为是生产环境有这个问题，打note的话需要停机停服务，这显然是不现实的。

3.在LMR1M004中新增加的_SGTXT = TAB_DRSEG-SGTXT打上断点，选择全局，查看程序执行的步骤，然后查看标准代码看看是否有预留增强点。

4.发现MRM_INVOICE_POST实际上就是保存的处理函数，在其中的es_saplmrmp中的pointmrm_invoice_post_11中有对参数进行处理，所以在这个位置创建一个新的增强实施，插入以下代码块

然后点击激活进行测试，发现成功了。

以上就是整个处理过程，如果官方note无效的话可以考虑采用以上方式。

837859 - MIRO: Text transfer to accounting document

Symptom

It is not clear how texts are transferred from MM invoice documents to the FI follow-on document.

Other Terms

MIRO, FI document, SGTXT, transfer

Reason and Prerequisites

You post invoice documents in Materials Management using transaction "Enter Invoice" (MIRO).

Solution

The header text on the "Details" tab is copied to the document header text of the FI follow-on document (INVFO-BKTXT -> BKPF-BKTXT). If the FI Business Add-In (BAdI) AC_DOCUMENT is active, see Note 1025810.

The item text on the "Basic Data" tab is transferred to the item text for the vendor line item of the FI document (INVFO-SGTXT -> BSEG-SGTXT).

The texts entered in the item list are transferred to the other lines of the FI follow-on document.

• On the "Purchase Order" tab: DRSEG-SGTXT -> BSEG-SGTXT

• On the "G/L account" tab: ACGL_ITEM-SGTXT -> BSEG-SGTXT

• For posting lines from the "Material" MIRO tab, you cannot enter an item text in the same way as transaction MR22.

The text transfer to the invoice items (BSEG-SGTXT, except for the vendor line item) may differ in the enhancement LMR1M004 (EXIT_SAPLMRMP_004).
If this enhancement is active, only the contents are transferred from E_SGTXT to the other item texts in the FI document. To transfer the item text created in MIRO, the following line must appear at the start of customer-specific code:
   E_SGTXT = TAB_DRSEG-SGTXT
  Exceptions and special cases can be dealt with afterwards.

366412 - MIRO: Enhancement LMR1M004 item text

Symptom

Customer enhancement LMR1M004 makes it possible to automatically fill the item texts in the follow-on documents which are created when posting in logistics invoice verification (for example, with the purchase order text).
However, this function is not possible for multiple account assignment.

Other Terms

Multiple account assignment

Reason and Prerequisites

This is caused by the program design.

Solution

This is changed for Release 4.6B and 4.6C via Support Package.
This program change now causes the customer enhancement also to be run through for the multiple account assignment for every account assignment item; the item text determined in the customer enhancement is contained in the follow-on documents.
