I need to add a new button in the extended search functions tab in RMWB transaction. When you run tansaction RMWB the initial screen will come with Recipe,Substance, Packaging, Material & Favourites in the navigation area of the screen. And when you double click on any on the application are on the right side will change. And in the application area there are boxes for validity area, Restricting criteria for search and extended search funtions. My requirement is to add a new button in Extended search functions to search for specifications having a text in a defined field. So when you click on the button it will pop up a screen where you can enter the text to search. Can anyone provide any solutions for this.
