Hi All,
I have a requirement to create a function module (input will be Opportunity ID and ERP Quotation ID) to create linkage between CRM Opportunity and ERP Quotation and vice versa.
I have already created the linkage from CRM Opportunity to ERP Quotation and now it is showing in Transaction history of Opportunity.
I have done this using CRM_ORDER_MAINTAIN.
Now I am struggling to create a linkage from ERP Quotation to CRM Opportunity in CRM system. I want to show the Opportunity in ERP Quotation page under transaction history in CRM. Whenever user execute that FM with both Object ID it should create the linkage in both direction.
I have searched a lot on SCN but could not find.
Can someone please help ASAP 
.
Many Thanks,
V Singh
