Different field type error

Question

plz solve this query:
SELECT ERDAT KUNNR NAME1 NAME2 LAND1 REGIO ORT01 PSTLZ SORTL STRAS TELF1 MCOD1 MCOD2 MCOD3 FROM KNA1
INTO CORRESPONDING FIELDS
OF TABLE IKNA1 .
SELECT CHANGENR CHANGE_IND FROM CDHDR INTO CORRESPONDING FIELDS
OF TABLE ICDHDR for all entries in ikna1  WHERE OBJECTCLAS = 'DEBI' AND
<b>OBJECTID = IKNA1-KUNNR</b> AND UDATE IN S_UDATE.
here the bolded field are showing error as one is of length 90 and other of 10.
please help how to check this.
<b>error</b> - when using "for all entries in itab" the fields OBJECTID and IKNA-KUNNR must have same type and length

Answer 1

then create one more table ikna1_temp, which will have KUNNR length as 90.
LOOP AT IKNA1.
MOVE-CORRESPONDING IKNA1 TO IKNA1_TEMP.
APPEND IKNA1_TEMP.
ENDLOOP.
and use the other table in second query.
Because the field type and length has to be same otherwise it will give an error
SELECT CHANGENR CHANGE_IND FROM CDHDR INTO CORRESPONDING FIELDS
OF TABLE ICDHDR for all entries in ikna1 WHERE OBJECTCLAS = 'DEBI' AND
OBJECTID = <b>IKNA1_TEMP-KUNNR</b> AND UDATE IN S_UDATE.
I had to take similar steps in order to get data from CDHDR table.
