Answer 1

thanks all for the answer , but i will try explain better my problem :
i have a it_data interntal table with document bill record i do a loop to that table and used the vbeln field in the FM for get the docment flow of that document billing number now the output of the FM is a table and i need take each record of that table am make it part of the current record of it_Data.
Example:
it_Data without the it_docflow data
*Sales ORg*   *Distri.Channel*      *Billing Type*    *Payer*         *Sold-to-party*        vbeln*
TP01         C1                     ZT17           1000524     1000524                 85003435 ..........
it_docflow table ( FM Output ):
*DOCNUM     ITEMNU    DOCNUV    ITEMNU            Description*
53107842   000000                          000000         Standard Order
65004606   000000       53107842   000000        Outbound Delivery
75179356   000000      65004606   000000         Invoice
57000118   000000      75179356   000000        Returns
85003435   000000      57000118   000000        Credit for Returns
5200003681 000000     85003435   000000       Accounting Doc.
now the it_docflow data add in the it_data record:
53107842  Standard Order  65004606 Outbound Delivery 75179356  Invoice  57000118 Returns  85003435 Credit for Returns 5200003681 Accounting Doc   TP01         C1                     ZT17           1000524     1000524                 85003435 .........
i hope this explain better my problem here , thanks again
