Compare multiple variable selections between two internal tables

I am trying to work out the syntax for the following, however i am stumped on the 2nd part of the requirement....
I have two internal tables. and i need to compare the records.
1st, line by line, which i can do, however the 2nd requirement, i need to check a range of data against the same table...
here is an example of the tables:
Internal Table1 has the following records.
TL1
TL2
TL3
TL4
TL5
TL6
Internal table 2 has the following records...
LDOC1 TL1
LDOC1 TL2
LDOC1 TL3
LDOC1 TL7
LDOC2 TL1
LDOC2 TL5
LDOC3 TL6
LDOC3 TL7
but for the 2nd requirement, i have to group the LDOC1 (2, 3) and search for all TL* and report if they all exist, some exist or none exist within the 1st internal table.
so for requirement 1, the answer would be yes (as i can do a read table using the TL*), however i am not sure how i can check "for all entries" for TL1, Tl2, TL3, TL7 and return that only some entries exist.... LDOC1 should return "some", LDOC2 should return "all" and LDOC3 should return "none".
Hopefully that makes sense???
Can someone give me a keyword to investigate as i am not sure the At new would work.... Unless i do an at new and then loop and maybe add the record to a "range" to then compare and log the result as it runs through each result...
so if Itab1 = itab2 then variable = yes. else None.
if variable = yes, and itab1 = itab2 then variable = yes.
if variable = yes and itab1 <> itab2 then variable = some.
would that work?? i am worried about performance too as there could be 1000's of records....
and can i have an "at end" so at end, if variable = yes, then variable = all?
i have written all the rest of the report to get all the data into these tables... i am just a little baffled as to how i can validate and compare the multiple selection.... :o(

Hi,
It is really confusing :-).. But i have tried to figure out.. may be this could be useful for you.
Internal Table1 has the following records.
TL1
TL2
TL3
TL4
TL5
Internal table 2 has the following records...
LDOC1 TL1
LDOC1 TL2
LDOC1 TL3
LDOC1 TL7
LDOC2 TL1
LDOC2 TL5
LDOC3 TL6
LDOC3 TL7
itab3[] = itab2[]
sort itab3 by field1.
delete adjacent duplicates from itab3 comparing field1.
itab3
LDCO1
LDCO2
LDCO3
loop at itab3.
clear: lv_flag, index, ind.
loop at itab2 where field1 = itab3-field1.
index = index + 1.
read table itab1 with key field1 = itab2-field2.
if sy-subrc NE 0.
lv_flag = 'X'.
ind = ind + 1.
endif.
endloop.
if lv_flag = 'X'.
if ind = index.
lv_val = 'NONE'.
elseif ind NE index.
lv_val = 'SOME'.
endif.
else.
lv_val = 'ALL'.
endif.
"here you can modify itab3 with lv_val in one field, so that you can figure out which is SOME, NONE, ALL
endloop.

Find the difference between two internal table

how can i see the difference between two interal tables?
The requirement is as follows
1. We have a transparent table, which stores the employee data with EMP ID as key.
2. We load the transp table data into a interal table (B).
3. We get data from legecy system as file and it gets loaded into another internal table (A) (this also has the same EMP ID key and this will have latest addition/update to those emplyees).
Now we need to seperate out these data into three interal table Inserted (I), Deleted (D) and Updated (U).
We want to do followign things
I = A - B
D = B - A
Both A and B will have around 40k records. Hence we are trying to avoid the looping.
Please suggest the best option for us.
Thank you in advance.

Hi Raghavendra,
Currently as of my knowledge, these operations are only possible through LOOPs. But LOOPign can be really fast here if you properly utilize the SORTING, READ with BINARY SEARCH and FIELD-SYMBOLS usage. I would say:-
Steps for Insert:-
SORT: A, B.
LOOP AT A ASSIGNING <WA_A>.
READ TABLE B WITH TABLE KEY key = <WA_A>-key BINARY SEARCH.
IF SY-SUBRC NE 0.
APPEND <WA_A> TO I.
ENDIF.
ENDLOOP.
Steps for Delete:-
SORT: A, B.
LOOP AT B ASSIGNING <WA_B>.
READ TABLE A WITH TABLE KEY key = <WA_B>-key BINARY SEARCH.
IF SY-SUBRC NE 0.
APPEND <WA_B> TO D.
ENDIF.
ENDLOOP.

Data Transfer between two internal tables

Hi SDN,
If I have two internal tables itab_a and Itab_b and I want to copy a subset of itab_a to itab_b using a conditional statement, is it possible and how?
Second, what if I want to append the smaller internal table itab_b to itab_a, how would you do that.
My task is to take some of the rows from a into b, change one field and append back to a. So if a had 100 rows, now it would have 110.
Please help.
Thanks.
Saf.

Cann't move data between two internal table in Unicode program

Hello expert,
I import a program from old sap system to new system, but syntax error occurred --- ' L_T_S776[] = T_DATA_RECORDS[]. ',
it is said ' internal table L_T_S776 and T_DATA_RECORDS are not mutually convertible, in unicode program, two internal tables must have the same structure layout'.
The coding is:
DATA: L_T_S776 LIKE S776 OCCURS 0 WITH HEADER LINE.
DATA: L_T_S777 LIKE S777 OCCURS 0 WITH HEADER LINE.
FIELD-SYMBOLS: <F_S776> TYPE S776.
FIELD-SYMBOLS: <F_S777> TYPE S777.
IF NOT ZCL_USEREXIT=>IS_ACTIVE( PROJN = 11 EXITN = 34 ) IS INITIAL.
CASE I_RMCP2-SCTYP.
 WHEN 'Z776'.
 L_T_S776[] = T_DATA_RECORDS[].
 LOOP AT L_T_S776 ASSIGNING <F_S776>.
 <F_S776>-ZZCUSER = SY-UNAME.

 <F_S776>-ZZCTIME = SY-TIMLO.
 ENDLOOP.
 T_DATA_RECORDS[] = L_T_S776[].
 WHEN OTHERS.
ENDCASE.
internal table T_DATA_RECORDS is defined to like INDX.
this program is in function module EXIT_SAPMMCP6_011, it is a user_exit.
I also confuse the meaning of this part of coding, could anybody help me?
reward if got useful reply, thank you.
H.B

Hi,
The structure are different thats why you getting this error. But there must be some fields common to which you want to move data. So you change in that way.
And there will be no impact whatsoever because of such change.

Can we apply join between two internal tables?

Itab has fields A,B,C.
Data: begin of itab occurs 1,
         A type I,
         B type I,
         C type I,
         End of itab.
Jtab has fields A, I, J.
Data: begin of itab occurs 1,
         A type I,
         I type I,
         J type I,
         End of itab
The common field between itab and jtab is u201CAu201D.
Now I need to collect A,B,C,I, J in another internal table ktab.
How should I be doing this.
If I use a SELECT query with inner join between itab and jtab it says u201Citab is not a database tableu201D.
How should I get the result ktab with A B C I J fields?
Please help, nay help will be highly appreciated?

Do you have the above code in ?
Here A is common field between both tables, first we are appending itab_1 & itab_2 into table itab_all then deleting the adjacent duplicates from itab_all. then we are reading itab_1 & itab_2 for possible matches and update the same values in itab_all
so there will NOT be a chance of duplicates in itab_all

How to append records between two internal tables

hi all,
im trying to append from an internal table to another internal table with same structure. i tried the following but it overwrites previous contents of i_dest:
move i_src to i_dest
thanks,
sid

hey u try to move it record by record
itab2 = itab.
append itab2.
This should work I guess
just check the code below, if u want to move the whole itab into itab2 then use itab2[] = itab.
loop at it_pgm.
read table itab with key obj_name = it_pgm-pgm_name.
if sy-subrc = 0.
 itab_final-obj_name = itab-obj_name.
 itab_final-func_spec = itab-func_spec.
 itab_final-func_area = itab-func_area.
 itab_final-dev_class = itab-dev_class.
 append itab_final.
else.
 itab_alt-pgm_name = it_pgm-pgm_name.
 append itab_alt.
endif.

Using for all entries of two internal tables in where clause of the select

Hi experts,
My requirement is, need to select Marc-minbe and wrpl-sobst, for all the entries of the two internal tables it_mara , and it_t001w.
here is the select queries i have used,
select matnr normt from mara into it_mara for all entries in it_data where normt = it_data-normt.
select konnr werks from t001w into it_t001w for all entries in it_data where konnr = it_data-konnr.
now i need to select minbe of marc table and sobse of wrpl table for all the entries of above internal tables, it_mara and it_t001w, using both matnr of it_mara and werks of it_t001w in where condition.
Pls advise how i can do it.

Compare two internal tables

hi everybody
i have two internal tables ITAB1 AND ITAB2
I WANT TO COMPARE THE CONTENTS OF THESE INTERNAL TABLES HOW TO DO THIS
REGARDS
HRIDHANJILI

Hello Hridhayanjili
The most detailed comparison is to use the same logic as change documents are prepared. Assuming both of your itabs are of structure struc_a. Then define the following type:
TYPES: BEGIN OF ty_s_itab_di.
INCLUDE TYPE struc_a.
TYPES: CHIND TYPE bu_chind.
TYPES: END OF ty_s_itab_di.
TYPES: ty_t_itab_di TYPE STANDARD TABLE OF ty_s_itab_di
WITH DEFAULT KEY.
DATA:
gt_itab_old TYPE ty_t_itab_di,
gt_itab_new TYPE ty_t_itab_di.
Fill itabs gt_Itab_old with the corresponding data of itab1 and gt_itab_new with the corresponding data of itab2.
Very important: sort you itabs either by all key fields or by all fields.
Call function CHANGEDOCUMENT_PREPARE_TABLES with the following parameters
- CHECK_INDICATOR = ' '
- TABLE_NEW = gt_Itab_new
- TABLE_OLD = gt_itab_old
The function module will remove identical lines from both itabs. New entries in gt_itab_New will have CHIND = 'I' and deleted entries in gt_itab_old will have CHIND = 'D'.
Read the documentation of the function module and play around with it. You will see that this a quite easy yet powerful approach for comparing itabs.

Uwe

Comparing two internal tables

HI all!
I have two internal tables with single field values as below :
1st Internal Table : A,B,C,D
2nd Internal Table : A,B,C,D,E,F,G,
Now I want to compare these two Int. tables and delete the second int. table with values which are not there in the first int. table.Any simple logic to get this.
Regards
Pavan

Sort internal table 1 by A B C D.
Now ..
copy contents of 2nd table to a temp table.
loop at 2nd internal table.
read 1st internal table with key a = 2internal table a
b = 2internal table b
c = 2internal table c
d = 2internal table d.
if sy-subrc ne 0.
delete entry from temp table.
now refresh table 2.
copy contents of temp to table 2.
Guys,
I guess DELETING THE SAME TABLE WITHIN A LOOP .. ENDLOOP is not advisable.Please correct me if i m wrong.

To compare two internal tables and delete records

Hi friends,
 I have to compare two internal tables and should delete the records which is not present in both the tables. Reply me as soon as possible.
Thanks.

Hi Nagarajan,
1. I don't think there is any direct (one-shot statement)
 way to achieve this.
 one has to do by writing some logic.
2. Loop at ITAB1.
 Read table ITAB2 with key Field1 = ITAB1-Field1.
 If sy-subrc <> 0.
 delete ITAB1.
 endif.
 Endloop.
Do the same again with ITAB2.
 Loop at ITAB2.
 Read table ITAB1 with key Field1 = ITAB2-Field1.
 If sy-subrc <> 0.
 delete ITAB2.
 endif.
 Endloop.
3. If any better way is found, i will let u know.
Hope it helps.

Reg comparison of two internal tables

hi friends,
please help me solving this.
there are two internal tables t_zvs38 and t_value
1.t_value like seahlpres
2.t_zvs38 like zvs38.

Appending two internal tables

hello friends,
I have two internal tables of different structure.
i have filled those two internal tables using join statements.
But one field is common in both the tables, when i try to append both tables into another new internal table.
i cant get the value for the 2nd tables field.
EX.
vbeln is common in vbuk, vbup, vbap, vbak, likp, lips.
but its sale order number in vbak, vbap.
delivery document in likp,lips.
vbup has both sales order and delivery in the vbeln field.
so, i made a join to between vbak, vbup and lips to see the goods movement status in vbup.
for that the vbeln should be delievery number.
and in other table, i have added vbup and vbak and vbep to get the delievery status.
for that the vbeln should be sale order no.
when i append both the tables into the third internal table that has the structure of both internal tables.
i could not get the vbeln of the second table(sale order no) in the third table.
