How can I obtain the first 10 charcter from field and the last 4 characters

Question

Hi
   I need to obtaind the first 10 characters from field AWKEY from BSEG table, and the last 4 characters, how can I obtain certains position from field??
    Example:
  AWKEY field from BSEG can be for example :
51000573112002
   This mean that you can obtain separately:
5100057311 - BELNR (field)
2002- GJAHR (field)
    As you can see, the first 10 positions are BELNR and the last 4 positions are GJAHR.
     But sometimes you find in old rows:
5100057312US502001
     This mean that you can get from this field:
10 positions for BELNR : 5100057312
4 positions for BUKRS or WERKS : US50  - in this case, I don´t know if its is BURKS or WERKS...for this reason only I want to take only the first 10 positions and the last 4 position to compare.
4 posiition for GJAHR: 2001
   I rewards all the answers.
   Thank you.

Answer 1

Hi, thank you for yours answers
Let me try to explain more what I need to do:
I have a Internal Table that I create with EKBE table:
  SELECT  MANDT EBELN EBELP GJAHR BELNR BEWTP BUDAT
          MENGE WRBTR WAERS WERKS SHKZG DMBTR
          ZEKKN VGABE BUZEI
    INTO CORRESPONDING FIELDS OF TABLE LIST_EKBE
    FROM EKBE
      WHERE EBELN IN R_EBELN
        AND BEWTP IN ('E','Q','R').
The result is all the rows that have this conditions..then with this internal table I need to looking for each BELNR in BKPF table, but sometimes you can find the row compare EKBE-BELNR with BKPF-BELNR...but in many cases, you don´t find the row in this way, you need to add EKBE-BELNR and EKBE-GJAHR and looking for in BKPF with field AWKEY..
For this reason I CONCATENATE in this way:
LOOP AT LIST_EKBE.
    V_BELNR = LIST_EKBE-BELNR.
    V_GJAHR = LIST_EKBE-GJAHR.
    CONCATENATE V_BELNR V_GJAHR  INTO V_AWKEY.
    SELECT SINGLE MANDT BUKRS BELNR GJAHR AWKEY
    INTO (BKPF-MANDT, BKPF-BUKRS, BKPF-BELNR,
         BKPF-GJAHR, BKPF-AWKEY)
    FROM BKPF
    WHERE AWKEY = V_AWKEY.
ENDLOOP.
  But I saw that sometimes you don´t find the record in BKPF because the AWKEY is formed with BELNRBUKRSGJAHR....or may be with BELNRWERKSGJAHR ...I don´t know if is BUKRS or WERKS the second field...for this reason I try only read in the select..if its posible the first 10 postions and the last 4 positions...but Im not sure if its possible..
  The reason for that I looking for the BELNR field in BKPF field for AWKEY its because sometimes de BELNR in BKPF its different..example:
In EKBE you have:
BELNR: 5105618260
GJAHR: 2006
If you looking for in BKPF you don´t find sometimes exactly the field BELNR : 5105618260.. then you need try looking for the AWKEY field then you need to add BELNR+GJAHR..example:
BKPF:
BELNR: 5105611111
GJAHR: 2006
AWKEY: 51056182602006
But in other cases... I found that in AWKEY exist for example:
BELNR: 5105611111
GJAHR: 2006
AWKEY: 5105618260US502006
In the last case I supouse that I can divide in:
AWKEY: 5105618260-US50-2006 ... but I don´t know what its the field that have the information US50..may be is BUKRS or may be its WERKS
May be some people know what its exactly this field and can help me..
With the solution that some of yours give me..I don´t know the how I can make the select? and if its posible make in this way
Thank you a lot
