hi,

You cannot use the read statement you have to use

LOOP AT <itab> WHERE <field> EQ  <field>.
*  Do the processing
ENDLOOP.

You meant to say, looping the itab with those conditions and exit the loop explicitely if my condition satisfied...

Does it consume time of program execution...

but it is the only way to take multiple values.....read statement works for single value always

Hi,

If you want to check for record exits in the internal table or not with particular condition then READ statement oK or you can loop explicitely if condition satisfied exit there will be difference in time consumption...

but if want to do the processing on all the records which satisfies the condition then you need to use the LOOP AT WHERE...ENDLOOP statement.

Hi,

Can you please be more Clear..

If you want to read a single record from the internal table then we use READ Statement.If you want to retrieve more than One record the use LOOP.ENDLOOP..

(I) LOOP AT IT_HISTORY INTO WA_HISTORY WHERE EQUNR = WA_ESN-EQUNR

AND BWART EQ '351'

AND SHKZG = 'H'.

ENDloop.

(II) LOOP AT IT_HISTORY INTO WA_HISTORY WHERE EQUNR = WA_ESN-EQUNR

AND ( BWART EQ '351' OR BWART EQ 'Z13' )

AND SHKZG = 'H'.

endloop.

My IT_HISTORY contain data only with so many BWART = '351' and bwart ='Z13' records..i want to catch the very first record which satisfies the condition BWART EQ '351' OR BWART EQ 'Z13' .

which statement take longer time of execution...

Hi,

You can not use READ statement. You have to use LOOP and ENDLOOP.

You want to do for all records satifies the condition then you use LOOP AT ITAB where (your condition) ENDLOOP.

If you want to check for already existing records in the ITAB with parcticular condition then use READ statement.
