Introduction

Most of the companies are maintaining some of the transactions in Flat file (Excel Sheet) and they want to load that flat file to SAP BI, there are multiple ways to load Flat file into BW.

BI consultant will maintain the Data flow for that flat file and whenever file will come via an email or any other way, BI person will load it manually on daily basis but this is not the right way to load flat file.

BI consultant uses any tool to transfer the file from client to Application server and load from there via process chain. But this is also not a best practice in all the types of operating system specially Windows. Because while transferring the file virus will also move and that will create problem in server so the best way is to transfer it via ABAP Code.

This document will discuss how can load data from file to ABAP table and then we will load the same to BI object.

User just needs to run a Transaction code and select the corresponding file, he want to load.

Create table

Create a table in BW that will store the records structure of that table will same as flat file

“ZTEST is ABAP TABLE in SAP BI System that will store the records coming from Flat file

TABLES ZTEST.

DATA: BEGIN OF WA1,

MAT(18) TYPE C,

PLANT(5) TYPE C,

END OF WA1,

ITAB LIKE TABLE OF WA1,

WA_FINAL LIKE ZTEST,

ITAB_FINAL LIKE TABLE OF WA_FINAL.

DATA STR TYPE STRING.

DELETE FROM ZTEST.

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

FILENAME = S_FILE

FILETYPE = 'ASC'

HAS_FIELD_SEPARATOR = 'X'

TABLES

DATA_TAB = ITAB .

DATA J TYPE I.

DATA L TYPE I.

CLEAR STR.

"The Following code will convert the data from internal table to Database Table

LOOP AT ITAB INTO WA1.

L = STRLEN( WA1-MAT ).

“Since data is Comma separated that's why a record will be a string

“e.g. M01, 1000 will be a single string that needs to be separated depending upon

"Commas in between the string

WHILE WA1-MAT+J(1) <> ',' .

CONCATENATE STR WA1-MAT+J(1) INTO STR.

J = J + 1.

WA_FINAL-MAT = STR.

CLEAR STR.

J = J + 1.

WHILE J < L .

CONCATENATE STR WA1-MAT+J(1) INTO STR.

J = J + 1.

ENDWHILE.

WA_FINAL-PLANT = STR.

CLEAR STR.

APPEND WA_FINAL TO ITAB_FINAL.

J = 0.
