Hi Rama,
Thanks for the tip.
When I debugged I got to know that the class /SAPSRM/CL_PDO_BP_UPDATE_BUFF gets triggered which handles all the data the user enters on the screen if the attributes are part of standard structures.
I need the data from the custom context attributes in the buffer when that class triggers.
Please tell me how to get the data into buffer.
This is a standard process for registration of suppliers in SRM. Sorry for not mentioning these details earlier.
Thank you,
Anish
