Dear Niranjan
the WWI design of a cover letter is very "company" specific. In most cases data like:
- which material number was "delivered" is shown e.g. with material text
- some contact adress data from the company shipping the MSDS is shown
etc.
Most of the information printed are retrieved using a parameter symbol. Some data might come from information in CVD1; some data is retrieved by using the data from CVD1; e.g. Customer adress information etc. (here data is retrieved from business partner information)
The parameter symbols you are showing are "standard"; therefore you can use option of Ralph to try to identify the "source" of the data as retrieved.
There are not many threads related to cover letter topic in this FORUM; I believe not more than 10 threads are related to this topic. I participated in discussion of one of these threads; i was not able to find the thread; sorry
Only as a hint: don't only concentrate on WWI design; identify as well how you need to "link" the cover letter to a specific "process"; this is done via customizing; e.g. refer to the SDS distribution OSS in which the whole SDS process is described; the process is described well how to "link" the cover letter to a shipment process
Topic is explained on "very" high level here:
Cover Sheet Template (DBV) - Basic Data and Tools (EHS-BD) - SAP Library
So I believe the best option is to us the proposal of Ralph and trying to understand the standard symbols etc.
