Document Search
If you do not remember the document number of the document that you want to open now, you must perform a document search. You can use either the normal matchcode or a special search transaction to do this.
Now let's have a look at the search transaction.
HANA Search
The HANA search function inside SAP Fiori launchpad enables you to search for documents. You can use the document search to search for an existing document across different business objects configured in your system.
The benefits of document search include:
Easy access of search fields from every page
Support for "wild" characters
Ability to filter search results

Limitations
A few things to consider before you search for any DIR:
Object link search for documents is not supported on the following objects:
Documents associated to a material BOM
Documents associated to a product structure node
Documents associated to a product structure variant
- On display of the search results, you can narrow down the search results by filtering. From the search results, you can go to different applications depending on the search you used.
Product Structure Browser
You have now created several master data for your forklift prototype in SAP.
Most of the master data is related to the material. The material has object-linked documents, is classified, or is the header material of BOMs and routings. This master data can now be displayed together at a glance.
To do this, you use the product structure browser.
You are able to display attached files of a document inside the browser or standalone.
You are able to add another object and compare them.
You are able to change the layout and add additional document or object information inside your screen.
If you work in a multi-SAP S/4/HANA environment, you are able to use this browser as a cross-system browser. Doing so, you have to define a filter which contains ALE or RFC destinations.
