Hi Archana,
Yes I have solved this, it is very simple, you have to go to spro --> IMG --> CRM --> pricing --> pricing catlog, add the standard field and corresponding element then save it will give a warning don't use the SAP name space..ignore that and continue to save it will ask the package you need go give the standard SAP package (for example for sales fields you need to give package name where all sales related configuration is saved)...
Hope this helps.
Regards,
Niranjan
