ABAP WebDynpro - Read URL Parameter
We have a Custom 'Catalog' that needs to be called from SRM using OCI (Open Catalog Interface). We are developing this custom catalog using ABAP Web Dynpro. We have following issues because of which we are unable to communicate back to Shopping cart from the Custom Catalog:
1. Unable to read the value of 'HOOK_URL' in WebDynpro application. We need this value so that it can be used as Exit URL. How and where do we read this URL parameter in ABAP WebDynpro ?
2. How can we return the 'HTML Form' to SRM with the values from Custom Catalog to fill the shopping cart ?
I would appreciate your help...
