First of all, Sorry if I have posted the question in wrong group.
I have one requirement in which first of all I create a sales order and then invoice through the report program after the invoice is created successfully I have to update the field XREF1 of BSEG for those line items for which the sales order and invoices are created. My issue is that I could not find the correct BAPI or FM to update the field.
There are number of FM's , I found on Google but all of them are NOT RELEASED.
Please help me if any of you have worked in such scenario,
Thank you in advance.
