Function

  

In JIT whenever the master data is changed[ JIT customer data , JIT Material data , JIT component group data ] the changes are updated in the database and not in the shared buffer. Hence the reorganization of the buffers needs to be triggered manually through the transaction  JITR ( report :- RJITMREO01)

   Options in JITR  

1)Recreate basic data in shared buffer

 

The first option refreshes the shared buffers.

JIT customer data – Data in Table JITCU is present in the buffer table JITSB  (CU)

JIT material data –  Data in Table JITMA is present in the buffer table JITSB (MA)

JIT part group – Data in Table JITPG is present in the buffer table JITSB(PG)

   

2)Reorganize JIT material master data  

This option is mainly use to remove the unwanted data in the table JITMA. It can also use to to find the scheduling agreements with a reason for rejection and then delete  them from JTIMA.  But inorder   to list out for deletion these   scheduling agreements has to fulfill   two criteria                                                                      

      

                                                                                 

                                                                                 

1) Scheduling Agreements will have  “reason for Rejection” set( which is set in this case)                                                                      

2) No entry corresponding to the scheduling agreement exist in  JITCO    table                                                                       

         

                                                                                 

                                                                                 

If there exist JIT calls corresponding to the agreement , the system   would not allow us to  delete those from JITMA , using JITR. In order for that we need to  create a  New scheduling agreement and map the    existing JIT calls to the new one   .This can be done by using the  third option of JITR       

           

      

                                                        

               

                                                                                 

Option 3: Transfer from new scheduling agreements into existing JIT calls               

                                                                     

 1.Create a scheduling agreement.                                      

  2.Create a JIT call with reference to this Scheduling agreement       

  3.Change the scheduling agreement and set a #reason for rejection#.   

  4.Execute JITR with option 3.                                         

  5.Create a new scheduling agreement with the same customer,customer   

       material and unloading point.                                     

  6.Now execute JITR with option 3.                                     

  7.Execute #Start Transfer#                                            

                                                                         

After this the JIT call is mapped to the new scheduling agreement.       

                                                                         

At code level these two criteria checking are happening in the           

function module   JIT03_GET_MATERIAL_FOR_REORG                           

                                                                         

                                                                         

   Line 48 (1)* only material where ABGRU isn’t initial                  

               ABGRU:- Reason for rejection                              

              DELETE jitma_sb_lt WHERE abgru IS initial. <<<<<<<<        

                                                                         

   Line 74(2)                                                             

                                                                                                                                                  

      SELECT DISTINCT matid FROM jitco INTO TABLE matid_lt              

     LOOP AT jitma_sb_lt INTO jitma_sb_ls.                              

      READ TABLE matid_lt INTO matid_ls                                 

           WITH TABLE KEY mat_l = jitma_sb_ls-matid.                    

      IF sy-subrc EQ 0.                                                  

           DELETE TABLE jitma_sb_lt FROM jitma_sb_ls.<<<<<<<<           

      ENDIF.  ” IF sy-subrc NE i1_gc.                                   

     ENDLOOP.                                                                  

                                                                      

                                                                     

  Release Dependencies

In the release DI 46C2, the option of refreshing the buffers is permitted on a single application server However, from the release DIMP 471 onwards, refreshing on multiple/all application servers is allowed.
