Buiding SRM custom application.

Hello SRM Gurus,

I have a very complex requirement to building a custom transaction in SRM.

This transaction has to control an invoice workflow in R/3 from SRM. Whenever there is a price or a quantity mismatch then through this custom transaction user will manage the discrepancy and update the R/3 invoice workflow from SRM.

I am not aware as to how to build an SRM screen and publish it to web. It will be good is you can send me a documentation for the same.

Any inputs will be appreciated.

Regards,

Shrikant.
