Hi San,
For seeing orders you can use CRMD_ORDER though, for seeing campaigns, I think crmd_order won't work since it's not under one order. There are three ways.
1) Transaction code CRM_MKTPL for seeing the details of the transaction.
2) In tables you can check in CGPL_PROJECT, CGPL_TEXT and other CGPL tables.
3) In code if you want to use cl_crm_mktpl_appl_base has a method called element_read which will read and give you all details of a campaign.
Thanks,
Faisal
