Restricting duplicate entries in for Batch Characteristics

Hi All,
How can we restrict duplicate values for Batch characteristics. The characteristics is a user input field but we want to keep a check that user doesn't input duplicate entries as in previous batches.

I think I misread your question.
When you say user doesn't input duplicate entries as in previous batches. do you mean the values in some other batch should not be entered in the current batch? For example, if in batch A, the characteristics Gold value reads as 1000 $, when the user creates the batch B, the user should not be allowed to enter value 1000$ for characteristic Gold?
If the assumption is correct, then I think standard configurations can't help. However take a look at the user exit EXIT_SAPLV01Z_014 in program SAPLV1ZN.I also recommend you posting this question in materials management forum after closing this thread, if you don't find suitable answer.
Regards,

Restrict Duplicate entry of record before saving the form

Hi!!
I need to validate duplicate entry of ITEM CODE before saving the FORM. Which means, if I have entered an ITEM CODE in a row, the same ITEM CODE should not be allowed to be entered in any other rows. It should throw an error message and should ask to enter another ITEM CODE instead. I did not get the correct logic from the threads.

hey i have a requirement that to restrict duplicate entry in both block(both multi record).the blocks are DEPT(MATER)
EMP(DETAIL)
the associated fieds in master block DEPT.DEPT_NO,in detail EMP.EMP_ID .
I have done' Kevin D Clarke’s calculated item ' both in master and detail block
its working fine for master block but in case of detail block its only respond to the current session(i.e. if the new value is inserted or save it will restrict another record to be inserted of that last record's value),it does not restrict duplicate value enter ,checking with other existing records(which are saved in earlier session,though after query it is shown on the form)
can anyone guide me why its not working

Restrict duplicate entry

how to restrict duplicate entries to be entered in a table control...
thanx,
naveen vishal

hi..
after ur PAI table control loop, write another module.
in tht u can declare one temporary int table and copy the original int table to the temp table.
then sort this new internal table and delete adjacent duplicates comparing your key fields.
if sy-subrc = 0.
give some error msg.
else.
do nothing..
endif.

Restricting duplicate entries

Hi
I have used an inner join to get data from two tables KNA1 and KNVP. In the result some entries are getting duplicated. How do i restrict it to get unique records???

Hi Mayur,
After selecting the datas you can delete the Duplicate Values from your internal Table.
For Internal tables use,
DELETE ADJACENT DUPLICATES FROM itab.
If u want to delete the duplicate entries depending on one or 2 columns then u can use
DELETE ADJACENT DUPLICATES FROM itab COMPARING f1 f2.
Thanks.

Change Documents for batch characteristics

Dear Guys,
Badly in need of your help !
In our project, we are required to report changes made on batches characteristics.
My program fetches records from CDPOS table that has change doc. object as 'CLASSIFY'.
The challenge is to find the new and old value. They are not directly stored in VALUE NEW and VALUE OLD. They are simply '1'.
I'm sure that they are stored somewhere in the database because the vlaue before and after change can be seen in the transaction mch3n via menu-> Display Change Documents.
I tried hard finding the table-field but looks like its not straight forward. This is really challenging.
Regards,
Ashok

Gert,
The change done in the project profile will only affect newly created projects.
Have you checked if change documents are created for new projects?
Hope this helps

FOR ALL ENTRIES IN - For Batch Split & multiple items

Hi,
My Report is to find Production Order from Sale Order.
Flow of tables -
(VBAK- VBAP- LIPS - SER01 - OBJK - SER05 - CAUFV)
Report is working accurate in normal scenario. But -
Here, In Batch split with multiple items -->
FOR ALL ENTRIES IN - is not taking values.
one case for Ex-->
sale order   so item        obdelivery           obd item           serial no
39782            10             1234              900001                 12
39782            10             1234              900002                 13
39782            20             3456              10                     14
Here,
only one OBD 1234 (sr no 12 & 13 ) is get entered in ITAB and not 3456.
(i.e. in gi_objkso all 3 entries are there, but in gi_objkpo only two entries are transferred)
Where, Production order is there for all three Sr. No.
My code is -->
IF NOT gi_ser01 IS INITIAL.
          SELECT obknr equnr sernr matnr
                 FROM objk
                 INTO TABLE gi_objkso
                 FOR ALL ENTRIES IN gi_ser01
                 WHERE obknr EQ gi_ser01-obknr
                   AND equnr IN so_equnr
                   AND sernr IN so_sernr
                   AND matnr IN so_matnr
                   AND taser EQ 'SER01'.
          IF NOT gi_objkso IS INITIAL.
                       SELECT obknr equnr sernr matnr
                   FROM objk
                   INTO TABLE gi_objkpo
                   FOR ALL ENTRIES IN gi_objkso
                   WHERE sernr EQ gi_objkso-sernr
                     AND equnr EQ gi_objkso-equnr
                     AND matnr EQ gi_objkso-matnr
                     AND taser EQ 'SER05'.

Hi,
Do you create more than one production order per sales order line? If not, you could change the match to look at table AFPO for fields KDAUF = sales order number) and KDPOS = salse item number.
If you are going down to serial number level, after this select (fields are indexed in index AFPO~3, by default I think), then you could use your additional serial number field match after getting the list of production order numbers for the sales order/item.

Restrict service entry sheet for reversal

Hi experts,
How can we put a check that service entry sheet should be reversed by the user who has accepted the same even from the same Plant, Purchasing organisation etc.
thanks in advance

hi Rajat,
Configure release strategy as below -
Two release codes for X (Say 19) & Y (say 20)
Give authorisation User X - Rel code 19 and User Y - Rel code 20
Configure SES release strategy wherein SES can be either released by 19 or 20 (See Pic 1)
Maintain classification
Now create SES & release with User X having authorisation for rel code 19 only (See Pic 2).
And then try to un-release with User Ywith release code 20, it will not allow & will give error "Not possible to cancel release with code 20" (See Pic 2)
User Y can not un-release with release code 19 as he dont have authorisation for rel code 19.
Try this out in TEST system, hope this will help you.
Reg, Rakesh

Validating Duplicate Entries In itab

Hi All
How to approach for restricting duplicate entries in the Database?
The scene is that I've to enter some data in a table control . and while saving, I've to check whether the same entry already exists in the database or not.
How to approach for this? Awaiting your valuable response.
Thanks in advance
Pradipta

Hai Mishra
DELETE ADJACENT DUPLICATES FROM itab.
Additions
1. ... COMPARING f1 f2 ...
2. ... COMPARING ALL FIELDS
Effect
Deletes neighboring, duplicate entries from the internal table itab . If there are n duplicate entries, the first entry is retained and the other n - 1 entries are deleted.
Two lines are considered to be duplicated if their default keys match.
The return code value is set as follows:
SY-SUBRC = 0 At least one duplicate exists, at least one entry deleted.
SY_SUBRC = 4 No duplicates exist, no entry deleted.
Addition 1
... COMPARING f1 f2 ...
Effect
Two lines of the internal table itab are considered to be duplicates if the specified fields f1 , f2 , .... match.
Addition 2
... COMPARING ALL FIELDS
Effect
Two lines are considered to be duplicates if all fields of the table entries match.
Notes
The DELETE ADJACENT DUPLICATES statement is especially useful if the internal table itab is sorted by fields (whether in ascending or descending order) which were compared during duplicate determination. In this case, the deletion of neighbouring duplicates is the same as the deletion of all duplicates.
If a comparison criterion is only known at runtime, it can be specified dynamically as the content of a field name by using COMPARING ... (name) ... . If name is blank at runtime, the comparison criterion is ignored. If name contains an invalid component name, a runtime error occurs.
Comparison criteria - statistically or dynamically specified - can be further restriced by specifying the offset and/or length.
Note
Performance
Deleting a line from an internal table incurs index maintenance costs which depend on the index of the line to be deleted. The runtime depends on the line width of the table.
For example, deleting a line in the middle of an internal table with 200 entries requires about 10 msn (standardized microseconds).
Deleting a range of entries with " DELETE itab FROM idx1 TO idx2. " deleting a set of entries with " DELETE itab WHERE ... " only incur index maintenance costs once. Compared with a LOOP , which deletes line-by-line, this is much faster.
To delete neighboring, duplicate entries from an internal table, use the variant " DELETE ADJACENT DUPLICATES FROM itab. " instead of LOOP constructions.
Thanks & regards

Updated Batch Characteristics on Order Release is not available in MSC3N

Hi All,
I have maintained the Class (023) and characteristics for Finished Material. When I am releasing the production order, I am assigning the values for batch characteristics (Custom defined characteristic) after that, If I go and see the corresponding batch in display mode (MSC3N) the value for the characteristic is not updated (entered value not available its blank).
u2022 Automatic batch creation for the production order during the order releasing is happening exactly as per the configuration but the entered value for the characteristic is not available for the corresponding batch in change as well as display mode (MSC2N/MSC3N)
Please guide to solve out this issue
Thanks in Advance

Hi Sanil,
Thanks for your speedy reply.
For me characteristics and all available as per the expectations but the updated value for the characteristcs on release is not sticking with the batch.
Please guide me to solve out this issue.

MySQL duplicate entry deletion in 5.5.9

Hey all,
I've noticed that in the newest MySQL, I can no longer do:
ALTER TABLE test ADD UNIQUE INDEX unique_index (id);
ALTER TABLE test DROP INDEX unique_index;
to remove duplicates. I get the following error:
ERROR 1062 (23000): Duplicate entry '3' for key 'unique_index']
This worked fine before the major SQL upgrade. It also works fine on version 5.1.52 on my web host. I searched through the 5.5.9 release notes and I didn't see anything that should have changed this, but I'm no MySQL guru! Is this a feature or a bug? Any alternate suggestions for deleting duplicates that will work on this version and older versions of MySQL?
Thanks!
Scott
Edit: Just for clarity, the table I'm working on has a single primary key column (UNIQUE_KEY) (with 80+ other data columns) and I'm only detecting the duplicate row based on the value of the primary key column.
Last edited by firecat53 (2011-02-25 03:33:30)

Alright, since I was apparently sucked in by this particular method the first time I googled the answer, care to enlighten me on the 'more practical' non-joke methods, as there appears to be more than one option.
Also, why is that a joke of a feature? Like I said, I'm no MySQL guru so I'm ready to learn!
Thanks,
Scott
edit: is this a 'more practical' method? It's hard when you're learning on your own to sort out the good from the bad sometimes
edit2: using the above method with this table:
+------+------+-------+
| id | data | data1 |
+------+------+-------+
| 1 | 10 | 100 |
| 2 | 100 | 1000 |
| 3 | 1000 | 500 |
| 3 | 1000 | 500 |
+------+------+-------+
and this query:
delete test from test left outer join (select min(id) as RowID, id from test group by id) as KeepRows on test.id=KeepRows.RowID where KeepRows.RowID is null;
I can't quite get it to work...it doesn't delete any rows. What am I missing there?
edit3: This method works -- is it a 'good' method or should I be looking at something different? Again, I'm just matching on duplicates in the primary key column (before the primary key is assigned):
create table test1 like test;
insert into test1 select * from test group by id;
drop table test;
rename table test1 to test;

To eliminate the duplicate entries while looping into final internal table

Hi friends,
IAam facing the follwoing problem.
Get Shipment for the Delivery number
      SELECT tknum
             vbeln
             INTO TABLE lt_vttp
             FROM vttp
             FOR ALL ENTRIES IN lt_vbfa
             WHERE vbeln = lt_vbfa-vbelv.
    IF sy-subrc EQ 0.
      SELECT vbeln kunnr
             FROM likp
             INTO TABLE lt_likp
             FOR ALL ENTRIES IN lt_vttp
             WHERE vbeln = lt_vttp-vbeln.
endif.
now iam my internal table lt_vttp i have following values
   shipment             delivery
      1000                  2000
      1000                 2001
in my internal table lt_likp i have the follwoing values
      delivery              shipto
       2000                  ABC
       2001                  ABC
now iam looping those values in a final internal table.
LOOP AT lt_likp INTO ls_likp.
    CHECK sy-subrc EQ 0.
     READ TABLE lt_vttp INTO ls_vttp WITH KEY vbeln = ls_likp-vbeln BINARY SEARCH.
    CHECK sy-subrc EQ 0.
         SELECT SINGLE * FROM vttk INTO ls_vttk
                WHERE tknum = ls_vttp-tknum.
              CHECK sy-subrc EQ 0.
            APPEND ls_vttk TO lt_vttk.
   endloop.
Now my problem is if the shipment is same and the shipto is same then need to eliminate the duplicate records.
        in internal table iam getting 2records with same shipment and shipto combination.
       but instead if both the shipment and shipto are same then i should elimate the duplicate entries.
and for the same shipment if i have differnt shipto then i neeed those 2 value.
can any body tell me how can i get that.
Regards
Priyanka.

Hi Priyanka,
In your code you are using seelct statement inside the loop which will affect the performance.
So, declare a another internal table which contains your both shipment and shipto elements with other required fields, say the name is lt_new.
sort lt_new by shipment shipto.
delete adjacent duplicates from lt_new comparing shipment shipto.
"then use for all entries to choose values from VTTK.
Hope this helps you.

Manoj Kumar P

BP Duplicate Entry Check - CRM UI

Hi Experts,
I am able to have duplicate entry check in CRM GUI but its not working in the Web UI. I want to do a similar check in CRM UI. I have to check whether its a corporate of individual BP. Then I have to display a warning message if a duplicate entry exists for the given fields.
In CRM GUI, I am using a function module to throw the message. Its called at an event.

Duplicate entries missing using for all entries in select query.

Hi Gurus,
Is there any way to avoid missing duplicate entries in an internal table if you use for all entries in select statement?
Note : i am selecting two tables using non key fields and i have to aggregate the data. I want only 2 data fields and one amount field in my final internal table. I can add all the primary key fields into my internal table and collect my required fields in another table, but I just want to know is there any other way to avoid missing duplicate entries without adding all the key fields?
Regards,
Raghavendra

Hi,
Just check what are the other possible fields in the table which may be having
duplicate entries and make use of them in the selection accordingly.
You may not miss any entries unless there is any restriction on them.
You can better judge that in debugging mode while selecting data from that table.
