A simple tool to calculate the total size of a BSP application

[JerryWang]

Today one of my colleague asks me whether there is some tool which can allow us to get a draft estimation on the size of a BSP application. As far as I know there is no such tool, so I write one by myself. This tool simply fetches source code of all artifacts belonging to a specified BSP application ( js, html, css etc ), accumulate the total number of characters returned by strlen().

You can simply create a report and paste the source code from this blog, execute it by specifying the BSP application name:

And the total number of characters in this BSP application is displayed:

According to ABAP help, in Unicode system 1 char occupies 2 bytes:

So in the example below the BSP application CRM_OPPRTNTY occupies at least 2011344 * 2 = 4022688 bytes.

Source code of report:
