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 2011 SAP AG 3
ABAP Program Write the following ABAP program in SE38 DATA S_FILE TYPE STRING. To Get Path of csv file that need to loaded in BI CALL FUNCTION 'WS_FILENAME_GET' IMPORTING FILENAME = S_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 FILETYPE = S_FILE = '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. 2011 SAP AG 4
ENDWHILE. 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. INSERT INTO ZTEST VALUES WA_FINAL. ENDLOOP. "FM to Trigger Event that will trigger Process chain of Data load DATA EVENT TYPE STRING. EVENT = 'ZPATH_IP'. CALL FUNCTION 'BP_EVENT_RAISE' EXPORTING EVENTID = EVENT. 2011 SAP AG 5
Create Data source Create a DataSource in SAP BI (RSO2 T-code) You can also maintain generic delta also in this data source 2011 SAP AG 6
Replicate that Datasource Replicate the Datasource from RSDS and activate it Create Transformation 2011 SAP AG 7
Create Info Package Create DTP 2011 SAP AG 8
Create Process chain 2011 SAP AG 9
Create an Event Create an event from SM64 that will trigger Chain. Start Condition of Process Chain Schedule the process chain 2011 SAP AG 10
Create a T-Code Create a T-code from SE93. User will just need to run this t-code Enter descrition and select start object as Program and selection screen(report transaction) Enter the ABAP Program name (ZINS_PATH) 2011 SAP AG 11
Run that T-Code Select File After running the T-code, A dialog will pop-up to select the file that is going to be loaded 2011 SAP AG 12
Check the Chain log Data is successfully loaded to BW 2011 SAP AG 13
