add temp bill to bill in RDY status

Just started at this company , we have a bill which is in RDY status which has 2 lines from a bill in TMP status   We'd like to combine

have the same bill by id

same invoice form id

same bill to customer ....  et al

However , when I pull up the option on the Billing Worksheet Page,  BI_TMP_SRCH_HDR page. to search for 'Add To Bill' , the Invoice in RDY status is not found.

The dba is trying to get me search functionality.  I have used this before in an earlier version.  We are on 9.2

Any pointer appreciated,

Thank you ,
