After research the BSP Application of Sales Order, Financing Quotaion & contract, I found that all of them use same Application CRMD_ORDER. But the layouts of them are different. The toolbar groups of Financing are LAM_O1_I & LAM_ODC1, and the toolbar groups of Sales Order are SLO_OICDEF & SLO_O1_IT.
But I check the toolbar groups LAM* in CRMC_BLUEPRINT_C I can not find any event in those toolbar group. So I am wondering that how the buttons show in Financing Quotation.
For the toolbar groups SLO*, there are lots of event.
