Enhancement to 0CRM_SALES_CONTR_I to add custom fields

Hi Experts,

We have added two fields Bill Type and the Invoice number in the data source 0CRM_SALES_CONTR_I. It also gets loaded when I check it from RSA3.  For this we have implemented user-exit EXIT_SAPLRSAP_001.

The problem we are facing is when we have multiple invoices, we can not get the link between C_T_DATA and the line item from table /1bea/crmb_bdi and /1bea/crmb_bdh. We need to display all the Invoices against each row in C_T_DATA.

Any guidance will be a great help.

Thanks & regards,

Harsha
