BW--ABAP code using BAPI's to load data into Cube from SpreadSheets

1 Requirement Description

We had a requirement to load data from a Spread sheet directly onto a Cube through an ABAP Program using the BAPI s in SAP BW.
We required a dialog screen to give location of file and to mention whether the load is Plan or Actual. Plan data load would delete the previous loads and Actual would add upon the data. This is done by the settings at the info package level.
Once the code is executed it loads file on the application server, and executes the following BAPI s to load data onto the cube.

2 Relation Function List

BAPI_IPAK_GETLIST - We pass the name of the Info source and Source system to get the list of related info packages.
BAPI_IPAK_GETDETAIL - It is used to get details of the listed info packages 
BAPI_IPAK_START - We pass the required info package name to start the load.
BAPI_ISREQUEST_GETSTATUS - To check the status of the request after an elapsed time and show a message regarding the same.
I am not an experienced ABAPer so the code has a lot of room for improvements, but as a BW guy I wanted to share the code because it was rather difficult in finding help on how to use the BAPI's
