How to run a webdynpro multiple times by passing different parameters each time and save webpages with parameter name?

Hi Experts,

I am a BW consultant and new to webdynpro. Not sure how to run RSO_METADATA_REPOSITORY multiple times and by passing different parameter values each time(either taken from an a standard BW table or user provided - anything is fine) and build web pages with parameter name. Need help with direction on where to start.

Let me step back and explain my requirement:

In BW we have an object called transformation.

One way of generating documentation for transformation is highlight transformation and press F1. Then its documentation will be opened as a local web page.

I need these web pages for all transformations. This is my requirment.

I came to know that RSO_METADATA_REPOSITORY is beeing used to generate this web page.

The web link is something like below:

http://ubw05.xxx.com:8005/SAP/BW/DOC/METADATA/?page=BW_O_D&SystemID=BWPCLNT100&ClassID=TRFN&ID=0KHR6J65AIIUTCJZEC093K6XDFV909PB&objectVersion=A&sap-language=EN&sap-client=100

When i run this link seperately(not by selecting transformation and pressing F1) i need to enter login credentials to BW system.

My challenges is how do i pass login credentials and multiple transformation IDs to generate multipe web pages with each page named by transformation ID?

WHere to start? First of all is RSO_METADATA_REPOSITORY Webdynpro JAVA or webdynpro ABAP or can i use anything?

Since it is beeing opened as local webpages i assume it is webdynpro JAVa is that correct?

Thanks,

Raghu
