Batch no. generation-possibility

Question

Dear All,
Is it possible to generate batch no(year basis-internal no. generation) with 105 movt type for one particular type of material i.e. specifically for one material group of ROH material type?
Please suggest the ways.
I this is possible, Another possibility i want as under.
     Year Base Internal no. Generation at the time of 105 movt for particular material group of ROH mat. Type                    
          No. generation should be as under               
           first two digits     Another 5 digits     Another 2 digits     
Toital digits-9     07     W0001                       01     
From two fields in GRN  i.e.    H124131                   C110 as examplas are given below.
Ex.
     Generated batch no                     (From Any two fields in GRN)     
                                                         1st field                  2nd field
                                  Vendor heat no     Vendor Coil ID
     07W000101            H124131                      C110
     07W000102            H124131                      C130
     07W000103            H124131                      C145
     07W000201            H1235                      C845
     07W000202            H1235                      C879
     07W000104            H124131                      C121
likewise
     My purpose is to generate Year Base Internal no. Generation at the time of 105 movt for particular material group of ROH mat. Type and that unique generation should be based on another two fields ( Vendor heat no & Vendor Coil ID) maintained at the time of 105 movt. This unique no. i am going to use in Prodn order and need tracebility of s/f batch from vendor heat no. and coil no. in final report.               
Any user exit or enhancement will do work.  I am very much need. So please suggest suitable ways.
Regards,
Vijay

Vijai,
Hi..Which steel plant were you working. I too was a steel prod man.
You can try the following exits for replacing the batch number proposed by the system with your own.
Try enhancement: SAPLV01Z
EXIT_SAPLV01Z_002 - using this you can change the batch number proposed by the system. Example: System proposes 000100123. You can change it to ABCD100123.
If you do not want sequencial counter for batch number, you can skip internal assignment in exit EXIT_SAPLV01Z_001 to specify your own batch number in EXIT_SAPLV01Z_002.
Hope this helps Please let me know if you have any problems.
